A 12V 100Ah lithium iron phosphate battery rated at 1280Wh, built as a drop-in replacement for Group 24 lead-acid, AGM and SLA batteries. It stands out for Bluetooth 5.0 monitoring of voltage, current, capacity and cell status, plus low-temperature charge cut-off and a 100A BMS. At about 21 lbs it is far lighter than the lead-acid it replaces, and buyers report it holds up under continuous load with little voltage sag. It suits RV, camper and off-grid users who want to watch their battery from a phone and expand later; long-term durability is still unproven for most owners.

Owners rate it well overall, with Bluetooth monitoring and steady output under load as the recurring highlights. Low-temperature protection and easy installation come up often. Most criticism is about plain build feel and the fact that few buyers have run it long enough to judge lifespan.
This 12V 100Ah lithium iron phosphate (LiFePO4) battery uses automotive-grade cells. It stores 1280Wh and is maintenance free. The cells are UL and IEC tested, and the battery is CE and RoHS certified.
It is BCI Group 24 size and replaces Group 24 lead-acid, AGM and SLA batteries without changes to existing wiring. A built-in 100A BMS protects against overcharge, over temperature, over discharge, over current, low temperature and short circuit. Low-temperature protection stops charging in cold conditions to protect the cells.
Bluetooth 5.0 lets you check voltage, current and capacity from your phone. Batteries can be connected in a 4S4P configuration to expand capacity from 1.28kWh up to 20.48kWh.
