Style: 12.8V 100Ah Mini(2 Pack)
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!

There was a mix up with the delivery (not the seller's fault), which took a couple of days to get resolved after contacting FEDEX and the seller. I got a response back from the seller (thru Amazon) within 6 hours. I ordered 8 of these 12V/100ah batteries and they all arrived very well packed with no damage. The initial voltage level of them averaged 13.53V. They will be part of a solar battery bank. I haven't topped them off, or put them thru a test yet, but they seem well made of quality materials, and the hard copy manual that came with them is written pretty well.

Style: 12.8V 7Ah
Ordered two 12v7ah batteries to replace spent SLA batteries in a Cyberpower 1500PFCLCD UPS. Installation was not smooth because the UPS stacks the batteries vertically, and the LFP batteries are about .05” taller than the original SLAs. The battery housing does not have .1” of wiggle room. Resolved the issue by sanding down the plastic housing between the batteries that has the battery cables. Remove the cables and connectors before doing this to avoid damaging them. Sand liberally. I didn’t take off as much and needed to wedge the batteries in the housing with some persuasion of the brute force type. Replacing them next time should be fun. I will come back to update my review in case there are any issues. Otherwise assume they are working well.

Great ah for the money! My rv will have plenty now. They complimented the solar nicely. They were at 40% full when I received them, and it took approx 9 hrs to charge to 100% at 17 amps. Really happy with them! They will run my small appliances easily!

Works well so far after one camping trip. With a 3000 watt inverter I powered my AC for an hour and had plenty to spare.

I installed two Dumfume LiFePO4 12 volt, 100ah Batteries (great specs for the dollar) with an all in one inverter, 800 watts solar panels, in my off grid shed. All is working well. I have high expectations for these batteries as they were vetted by Will Prowse on his YouTube channel recently. It is very important they have low temperature charging cutoff, verified operational on his YouTube. Time and performance will tell us more about this product.

With a few cycles from new to 14.6 v then to 11.6 v , the battery produced 105 amp hrs ( 5 amp hrs beyond advertised) with a constant 9.5 amp draw verified by a Powerwerx type digital meter. Impressive. Its very important not to leave the battery fully charge, rather draw 30-40 amp hrs out , then it can be stored. It came packaged well with a very rigid box and foam. No high amperage draws were performed . The two side carry handles showed no sign of fragility . Overall at least new it seems like a good buy.
