This is a 12V 100Ah LiFePO4 deep-cycle battery built to the standard Group 24 footprint, so it drops into trays and boxes that already held lead-acid or AGM batteries. Its 150A smart BMS gives enough current headroom for RV inverters, fridges and pumps, or a trolling motor over a long day, and Bluetooth lets you watch state of charge and cell data from a phone. It charges from a LiFePO4 AC charger, solar with an MPPT controller, or a generator through a DC-to-DC charger, and the BMS blocks charging below freezing. Against generic Group 24 lithium packs it stands out on BMS current rating and app monitoring; against premium brands it trades brand track record for a lower-cost direct fit.

Owners of the Vatrer Group 24 lithium battery generally report it drops into existing Group 24 trays and runs RV and trolling motor loads well, with the Bluetooth app useful for checking charge. Complaints center on the app and on charging behavior in cold weather.
This is a pack of four Vatrer 12V 100Ah LiFePO4 lithium batteries in the standard Group 24 size. They are made to replace lead-acid and AGM batteries in RVs, travel trailers, boats, trolling motor setups and other deep-cycle systems that already have a Group 24 tray or box.
Each battery has a 150A Smart BMS to supply current for loads such as an inverter, refrigerator, lights, pumps or a trolling motor. The BMS stops charging below 32°F to protect the cells from low-temperature charging damage. The ABS housing is rated IP65 for dust and water protection, and the design is moisture-resistant and salt-spray-resistant.
Bluetooth connects each battery to the Vatrer App, which shows state of charge, voltage, current, temperature and other operating data. The batteries can be charged with a LiFePO4 AC charger, solar panels with an MPPT controller, or a generator with a DC-to-DC charger. They can be wired in series and parallel, up to a 4P4S configuration.
