Real world test! I put four of the 12V 100Ah mini batteries on my boat to make a 12Volt 400 Amp hour bank. The bank is now at -411 Amp hours and still holding 12.6 volts!!! It's also supposed to have Bluetooth monitoring, but I can't figure out how to make it work. However,,, Absolutely NO WAY to contact the manufacturer for help!!! Website doesn't work and I can't see any way to contact them from the listing. ... show more

  • 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

  • Fits in Cyberpower 1500PFCLCD UPS with some slight modifications.
Size: 12.8V 7Ah Number of Items: 1
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. ... show more

  • So far so good with an amazing price
Size: 12.8V 300Ah Number of Items: 1
I used to pay $1k for 100ah lithium. Its hard to believe I got 300ah for less then half that. I bought 2. They fit perfectly in my RV. I've only used them for 2 weeks with 800 watts of solar. So far they haven't dropped below 80% running starlink, laptops, fridge and misc RV stuff. So far so good.

  • Quality materials & seem well built
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. ... show more

  • Meets all specs and has excellent output and capacity, but the battery may be difficult to charge.
The capacity of the battery indeed meets the rated 100Ah, and it can supply the power reliably under all conditions listed in the booklet. However, the battery I received started having charging issues only a few weeks in. So far, my personal experience suggests the battery doesn't like "smart" chargers even when they claim to be compatible with the chemistry. The end result is that when the battery is nearly full but the charger doesn't yet know it to be so, the end result is spikes in voltage that eventually lead to a complete shutdown with over-voltage errors. This has so far happened with every intelligent charger I have. If you can directly tune your charger to put out a constant measured voltage right at or just under the recommended 14.6v and ensure it doesn't produce voltage spikes above this, you might be all right. However, that's only an educated guess. ... show more
