  • Best bang for the buck battery I could find.
Size: 12.8V 200Ah Number of Items: 1
We purchased this battery to replace the lead acid battery our camper came with. It is a big battery, but I was able to fit it under the bench in our camper where the rest of the wiring was. I was able to go two days of boon docking while not trying to conserve battery life before charging and never got below 40% battery life. We were running our fridge and hot water tank on propane (both still use a little electricity to light), two vent fans, lights, at night, the radio, charge or phones, my dad's hearing aids, apple watches, air pods, and the water pump. I watched some YouTube reviews on other size battery's this company offers, and they all seem to be built really well. This brand has ender temp and over temp protection that actually works. I bought this to use, not review so I will not be tearing mine apart to confirm this, but I watched multiple videos from multiple sources. I do wish I had the extra money to buy the 300-ah battery. It is smaller and has a larger capacity, but for $268.00 I couldn't pass up this deal. If I decied to upgrade again, I will probably buy two of the 300-ah battery and move this one to my popup. ... show more

Good power. Rate of charge good IF you buy the right charger. Functionality good. Weight as expected with very nice handles. Terminals very easy to connect to. Using it daily for 30+ days without an issue.

  • Not a 300 amp battery I believe there's a 280 am battery components
Size: 12.8V 300Ah Number of Items: 1
This is a awesome battery that's performed spectacularly. However I don't believe it's a 300 amp hour battery I believe it's old components that make up a 280 amp battery. It's okay for my years but I would be suspect of it actually being a 300 amp hour battery

  • Excellent value for the price
Size: 12.8V 100Ah mini(2 Pack) Number of Items: 2
I bought 4 of these batteries for a total of 100ah @ 51.2v. I just ordered their, single, 51.2v battery as well. So far I've had no issues whatsoever. I've used an electric kettle(1500w for 10min) to boil water, an air fryer(1500w for 30min) to fry some wings, and the batteries delivered without a hitch. The batteries are so lightweight that moving them around from delivery to installation was really easy. They don't have Bluetooth, however, but I use victron components to monitor as much as I can. At this price, you'd be making a mistake not to buy. ... show more

  • Cheap for a reason
Size: 12.8V 100Ah mini(2 Pack) Number of Items: 2
I've had two sets and both have worked for a week or three and then started operating poorly - not taking a full charge, or taking a full charge and then immediately being down like 10% - feels like a dead cell AGAIN Amazon/ manufacturer denied my claim on getting replacement. So I'm out money and time on this garbage. Run away. Amazon told me to dispose of item and now manufacturer wants me to return it. Talk about a mismatch in policy. Yall need to figure this out. I want my money back for this garbage product. ... show more

  • These seem like first class batteries at a great price.

My expanded storage now means my off grid solar runs for days and weeks without interruption. Just added an 10K BTU AC load for the summer. I feel smug.

  • A good choice.
Size: 12.8V 100Ah mini(2 Pack) Number of Items: 2
Packaging was excellent, manual and instructions were simple to understand, called for them to be charged to 100%, but they were already fully charged. The mini size fit well in my Lance trailer try. They physically look great. I had to upgrade my controller so I decided to have a professional do that along with converting my DC from 6v to 12v. Finally, the price was right and so were most of the reviews. I'm 100% pleased! ... show more
