Style: 2 Pack 12.8V 100Ah
I’ve now built two solar PV setups using these GRNOE 12V 100Ah LiFePO₄ batteries, and both have been a great success. The batteries feel solid, lightweight compared to lead-acid, and they really do hold the energy longer, which makes a big difference when running loads off-grid. The 100A BMS with low-temp protection gives peace of mind, and so far they’ve handled charging and discharging cycles smoothly without any issues. Packaging was also excellent—secure and protective on arrival. If you’re working on a solar system and want reliable storage, these are a great choice. I’m happy to recommend them.

Style: 2 Pack 12.8V 100Ah
I’ve been building my own solar setups for a while, and this 2 pack has been an excellent choice. Right out of the box, I was impressed with how well packaged they were and how lightweight they felt compared to my old lead acid batteries. They’re solid, well built, and easy to handle. I’m using them both in my home backup solar system, and they’ve been performing flawlessly. They hold their charge for a long time, the 100A BMS with low temperature protection gives me peace of mind, and so far the charge and discharge cycles have been smooth and consistent. Performance has been excellent, no voltage drops, no overheating, and very stable output. If you’re putting together a solar setup or need dependable power storage, these batteries are a great investment. I’m really satisfied with them and would definitely buy again.

Style: 3 Pack 12.8V 100Ah
These batteries are great. Work great with trolling motor. About same size as lead acid car battery but lighter. I own 5 of these. Using 4 of them as a 48v solar battery bank and the other for my boat. Just make sure to to maintain them when not in use.

Style: 4 Pack 12.8V 100Ah
All 4 of my 100Ah batteries showed up at about 90% SOC. I topped them each off then did a capacity test before installing them in my golf cart. They all tested between 99.8Ah and 101.2Ah. Rite on the button of claimed capacity. Drove the golf cart around with the kids for a half hour or so and my shunt meter got up to 135A while accelerating and the batteries handled the load just fine without issue. After the half hour my meter still showed the batteries at 79% So full charge should get me about 2.5hours of easy casual driving.
