20 Best Battery For Solar Off Grid (2022 Updated)

Side of battery says [12V 100Ah/10Hr] to 10. 5V! Which is a full discharge and will not be good if you want to junk them too soon. They recommend 50% discharge for longevity, ~Im guessing 50. 2V for 48Vsys or 12.

56V for 12Vsys. If you paid for this battery, and you actually need capacity, $230/50Ah for 500-800 cycles of 60Wh x 650 cycles. Lastly! There is a C# Rating. Which essentially a reference spec that says the faster you discharge over benchmark of 100Ah/10H, it will dynamically use more than rated capacity and need to charge more often or sooner.

Constantly worrying about over-specified bench-line performance is not fun, for you or the battery, and in my case a battery Bank.

Thus far its working as expected. The capacity appears to be there, self-discharge rate is very low as expected, and it’s 100 AH rated, which I’m not about to draw down 100% to find out — but it appears to be an honest rating.

Pricing is fair, especially when one considers that a battery of this size is quite heavy and thus shipping is not cheap. It came well-packed which was appreciated and prevented damage in transit. Time will tell whether durability is also as expected; you can probably do better on the durability side with LiFePO4, but at material additional cost, never mind the charger required is different (and more expensive) as well.

For me, at least with my needs, SLA is plenty good enough. This is the primary 12V storage for a modest cargo-to-RV trailer conversion and is working well.

I use this battery in a 5th Wheel that is parked on my mountain property. It runs the microwave and all 120v circuits through a Renogy 2000w inverter. Charging is done by 400 watts of solar. I charge various constructuon 18v tool batteries and even other RVs through the inverter.

This AGM 12v 200ah batteey has power and depth. I thought I needed 2 of them, but one has done the job. I hope it will last several years.

Got the product on time, no damage. Tested the battery at 0. 2C rate and got full 50Ah out of it. So far put 15 cycles and it is performing well. I had few questions with the product and Renogy customer care team resolved them very quickly.

It will be good if their website has optimum battery characteristics in various charge discharge settings. For example a simple chart showing battery voltage and sate of charge relationship.

Renogy was kind enough to horror the sale price at the time I purchased since I had missed it by a week. Great job to the renogy group. Two 50ah lithium in my conversion van and their 1000 watt inverter, and off we go to the state parks.

Thank you renogy J. Saraceno.

It’s my first LiFePo big battery. I have a few small ones for remotcontrol battery and I’ll be working on solar cel soon to charge the bigger batteries I’ll be putting together soon. Thanks for keeping quality affordable -.

I am using one 100ah Amphere Time battery to power a 55 lb. thrust Motorguiide trolling motor. I have been out twice and am impressed with the performance. After a half day of using the trolling motor to troll at speeds ranging from 1.

8 to 2. 2 mph, I still have 60% battery capacity remaining. This was confirmed on a multimeter and by recharge time. It took 4 hours on a 10amp Lifepo4 charger to recharge each time. The motor is powering a boat that weights approximately 1200 lbs loaded.

The amp draw ranges between 16 and 22 amps at the speeds I am trolling. I am very happy with the product so far and would recommend these batteries. I will update the review at the end of the fishing season.

Purchased two lithium 200Ah Plus batteries several months ago for my 5th wheel RV. They are competitively priced and seem to be made of sturdy material. So far they have performed as advertised. Went 24 hours on battery only with fridge and water heater on gas.

We used the RV as we normally do with the TV, Dish satellite and lights as usual and had 35% left at the end of 24hours. They helped with the getting the correct settings on my charger/inverter and always answered my emails within 24hours.

So far I am very happy with the batteries and their customer support.

I have purchased them since it was a good value for the price and all reviews i have seen the units are just the same as the units that are priced much higher. I have not had time to install the units but in the spring when I get home I will be installing them and be using them full time since I am now living in my RV full time.

RV is equiped with washer, dryer, micro, hot water heater and all the rest of the appliances. At present time I am using 12 – 6 Volt lead acid batteries which run all my equipment so I will be giving them a good test and can give you a better report later.

battery go dead or has 1/4 of life in just 3 month ecommerce is a company that takes advatage from disable persons now i wasted my little income i get from suplimentalincome and now im stuck home in bed with no freedome cause this company wont lift a finger too help.

i have a powerchair that is now collecting dirt sitting at the foot of my bed! cause the batteries are no good! i will notify ada forums of this company and these junky batteries from MIGHTY MAX! YES MIGHTY MAX PRODUCT ARE NO GOOD!!!!!!!!!!!!! A WASTE OF AMERICAN WORKERS SELLING AND DISTRUBITING BAD PRODUCT!!!!!!!!!!!! DONT BUY PLEASE LOOK ELSE WERE.

LIKE APEX BATTERIES ARE BETTER!!!!!! MIGHTY MAX IS JUNK FROM CHINA!!!!!!!.

Excellent batteries. I waited to review, but I have them for close to 2 years now, so it’s time. I have 2 of them in parallel, because the 100AH was too heavy for me to lift. They are charged by a 100 watt solar panel through an EPEVER controller, and they have behaved very well so far, they hold the charge and the voltage is 12.

6 at rest, 13. 7 or thereabouts while charging. I would buy them again, and I recommend them.

Replaced my old batteries in chair with these and they hold less of a charge than my old batteries. Ive bought these before but this is the first bad experience Ive had with them. In my estimation they are not a good value for the money.

This is a great battery for off the grid camping. It easily held a charge for two weeks with our fifth wheel camper. Previous batteries would last maybe three days with luck. A constant battle switching batteries to keep things running.

With this battery there were no issues. It worked so well that when we got home we ordered a second battery just for peace of mind. You can’t go wrong with this.

I bought two of these for my Ham Radio set up. They arrived in perfect shape. packing on battery survived shipping easily. They are a well built battery very clean. easy carry handle. I also called Windy Nation prior to purchase and they satisfactory answered all of my questions.

I wish they were cheaper so I could buy a few more. but for right now I am perfectly satisfied.

Why does solar prices keep going up. I thought we were all told to go green.

The 822PS pump sentry system along with the Interstate 12v deep cycle battery make a great combination for my sump pump backup. Easy to follow instructions and it was up and running within an hour. A little pricey but now I have peace of mind.

Installed this battery with a backup system and a Zoeller M95 pump. The battery powers the pump perfectly. Should bide me enough time to get the generator going should I experience another power outage.

After plugging it to the inverter, it charged up. Tested it on the pump and it worked. Hope that the first power outage in a rain storm it works as it says.

I wish they were built better. Both batteries leak from the top caps which should be completetly sealed,

Very happy with my purchase. Will be used in my travel trailer. Good Value.

The batteries arrived in good condition, in spite of the fact that the pallet was pretty much destroyed. Kudos on how well the batteries themselves are packaged. I checked voltage on each battery and all were fully charged.

These batteries will be installed as soon as we get some good weather (Montana winters can get cool at times) and will replace the battery bank that has been in use for 14 years. Looking forward to having fresh batteries.

For cross country shipment it might be a good idea to split the 8 batteries between two pallets. Putting 1400 lbs on one pallet is probably a little much. Good job otherwise.

These Batteries are a great value. Powered 800 watts average 1000 amps intermittent, for 5 hrs still had 12.3 volts.I’m running a 1000 amp hour back. They are big and heavy. Highly recommend.

I have found this battery to be of good value. It has made my solar system capable of to meet my needs.

IšverstiShow in original languageBattery was delayed quite a bit by global supply chain and shipping events way beyond the control of ShopSolarKits or SOK. Excellent communication and response to queries during the delay.

Well worth the wait. The 206 ah battery will probably be more than I need for the next 10 or more years. It has been great so far. Couple of K-cups each morning, frozen meat and cold beer in the fridge, fans and lights and charging all my misc.

stuff in the woods and never even challenge the batteries capacity.

IšverstiShow in original languageSo far so good, but I haven’t subjected my two batteries to long term hard and deep actual use, only moderate to high loads for short maybe 30 minutes term, but they performed excellent under those conditions.

I was most impressed by the heavy well padded and protected shipping boxes and both batteries tested the same full charge upon arrival despite long shipping times. John Electrical Engineer.

IšverstiShow in original languageI really appreciated the communication and follow ups from Max and his team when I ordered my batteries. I will shop there again. Do not listen to the negative reviews due to spoiled entitled kids who think all shopping is like next day amazon.

Understanding over cancel. I will shop here again for all my solar needs.

I ran a 2000 watt rms fosgate amp no problem on 1 with a 270 amp alt. Have to get another one upgraded to the orion hcca 5000.1d so need a second one. They work with great success lol very nice!

The local Battery store where I normally purchase all my batteries from didn’t lower their price when the vendor ceased packaging these particular batteries in the 4 pack. So, now I found a new supplier for my batteries.

I use these batteries in our solar pathway lights.

Several solar lights in my yard refused to light, the batteries were old and no longer able to be recharged. I ordered the Ultralast from Max Warehouse. They were received quickly even though the pandemic had been delaying orders from other sources.

I am very happy with the batteries. my lights are now bright in my back yard.

I worked remote and have over the last year began to travel the country while doing so in our camper. My first camper had a 200ah AGM battery and 200w of solar, and while it worked on that smaller trailer, as I moved into something a bit more livable, the AGM battery just wasn’t covering it.

So I picked up two of these batteries, and so far so great! I’ve now traveled across and all around the country, and they’ve been without issue and provide tons of capacity. I do intend to get just one more though battery so as I can go really long periods of time off grid and possibly without solar (who wants to park in the sun in the summer?!?!?).

I just spent 5 days in Big Sur parked in the shade and thank god I purchased this battery. I probably only had 2 hours of sunlight each day to charge the battery with a 100w portable panel, and even then only one hour of that was I getting 100% out of my panels, this battery held up like a champ.

I was able to watch TV at night, charge our phones, run lighting, and play music in my square drop and after five days of abuse the battery only dropped to 56%. We would have been powerless with our old AGM after the first night.

Very happy that we purchased this battery.

So far I really like this battery in my sprinter van. Lots of power for the size/weight. Note that if you drain your battery all the way down to the point the BMS locks it out, you’ll need a special charger to “unlock” it.

I was doing this to calibrate my Renogy battery monitor, but the Renogy tech support failed to mention it would lock me out when recommending I do this for calibration. A second call back to tech support recommended I buy the NOCO Genius G1100 ($40 on Amazon) to unlock it which did the trick.

They also said 11. 2V is about drained for voltage. Other than bad advice costing me an extra $40, I do really like the set up.

These Batteries were purchased to replace an Identical make and model purchased 3 years ago. These were for the most part Identical to the last ones. Unfourtinatlly, the last ones failed in 3 years of very light use.

I can only hope these last longer, I could not find another brand in the time alloted that would replace them.

UPDATE: Below is our original review. We were very happy with these batteries at first, but less than four months later, they are not holding a charge at all. We’re forced to run our generator at night to keep the batteries from dying completely.

Original Review: We ordered 6 for our RV solar system – and they are great! Better than our old ones. (VMAX SLR125 AGM Sealed Deep Cycle 12V 125Ah batteries) These charge up fast and hold a charge. We actually just have 5 connected right now, and they give us more energy than our old batteries, and last through the night no problem.

(We were always checking the charge and sometimes having to start our generator in order to charge the old ones up while it was dark out. ) We’ve just had them three weeks, but so far, so good.

So I bought one of these late fall, at the end of camping season so I could get used to using it on my parked RV over the winter, to see how it worked. I ran a direct sonic mouse away thing on it with a 200w solar panel to keep it charged.

It wasn’t (the RV) parked to a place that was easy to get to so the panel often got covered up by snow and sure enough after about two months of not paying attention to it I went down and checked and the panel read like it wasn’t connected to anything.

I was disappointed and worried I’d have to figure out how to send it back and such, procrastinated for another month and on a warmer day went down and took a good good look at it. On a whim I plugged the ethernet cord/power switch to it and pressed it, sure enough the BMS had turned the battery to shelf mode.

Charged up to full on two sunny days and all was well. I’m expecting to be able to camp with a decent amount of sunlight and run my larger dorm fridge without too much of a problem with two batteries for at least a few days, but that’ll take a bit more testing and another battery.

As other reviews have mentioned, one of the biggest selling points of this battery is the “I don’t have to worry about it” and although it was disappointing that the mouse thing drained the battery (I’m not entirely sure it works all that properly), the battery wasn’t damaged like a lead acid battery would be.

> Before this happened I did go down to the RV one day when it was really cold and monitored it for a few hours. It barely got any charge from the solar panel but slowly warmed up and once it got up well over 40F suddenly the majority of power was going into recharging the battery.

That isn’t surprising as that’s exactly what its supposed to do.

I use 6 of these on a boat. Overall, I have a love and hate relationship with them. On one hand, there is some very serious engineering here, I think these batteries are very well built, they are impressive and they are an amazing value.

So I love them as batteries. On the other hand, whatever Renogy shows in electrical/mechanical engineering prowess, they completely lack in software engineering and product sense. App is quite terrible, there are no two ways about it.

It completely lacks a modern perspective on product concept, UX design, engineering design, implementation and quality control. Some examples: Clearly Renogy wants to be in the social business, why would a battery monitoring app requires social media features like a community? Who knows.

Can you skip it? No. You monitor multiple batteries, can you see which battery you are looking at when you go to battery details (serial number)? No. Do your batteries show up the same every time? No.

How many times do you need to reload the app and scan all batteries to see all 6 of them? Anywhere between 3 to 10 but never in one go. Can you see the total current in and out of all batteries in aggregate? Not since the last app update (some QA engineer failed to notice 6 serial numbers next to each other do not wrap on a single line).

This list goes on and on. I think there is a lesson for Renogy here. Unless they fundamentally rethink their software and apps, they may be an OK and maybe a good company, but never a great company. These are good batteries.

They could have been GREAT batteries with an app that simply offered what an average Victron bluetooth app offers. Without that they linger around 3 out of 5 stars.

We purchased two 200AH Bluetooth Lithium batteries. The batteries are hooked up to our system and work fine. they are batteries. Two things that could see improvement: 1) The app (Renogy BT) that connects to the battery via bluetooth is borderline unusable.

Sometimes only one battery shows up in the app to connect to, other times both show up. After selecting the battery to connect (assuming it shows up on the app), the information displayed is all zeros.

So if you’re fortunate enough to get a bluetooth connection to the battery, no info is actually being transferred from the battery to the app. 2) We are using a Victron Solar Charger and there are several parameters that are user adjustable in order to make solar charging as efficient as possible for a particular brand/make of battery.

i. e. Absorption Voltage, Float Voltage, Equalization Voltage, Re-Bulk Voltage offset. none of which I knew about before purchasing these batteries. Had I known, I would have purchased from a supplier that publishes such information.

After scowering their website and manuals with no luck, I eventually did get some of this info from Renogy after many attempts via email. At any rate, we are happy with the batteries, with the exceptions listed above.
