This is a two-pack of Vatrer's 12V 100Ah LiFePO4 deep-cycle batteries with built-in self-heating. When a charger is connected at 32°F, incoming power heats the cells first; charging starts once the battery passes 41°F, so you skip a separate heating pad. Each battery holds 1280Wh and recharges in about 5 hours on a 20A LiFePO4 charger, with solar plus MPPT or a DC-to-DC charger as alternatives. It suits RV, marine and off-grid users who camp or fish in the cold; against unheated budget LiFePO4 packs it adds cold-weather charging, but it is heavier and bulkier than heated rivals built on smaller prismatic cells.

Owners of Vatrer's heated LiFePO4 line generally report the heating works as described and charging resumes on its own in freezing weather. Complaints center on bulk, weight and slower cold-weather charging.
This is a 12V 100Ah LiFePO4 deep-cycle battery with built-in heating for cold-weather charging. The listing is for a 2-pack. It stores 1280Wh of energy and is meant for RV electrical loads, marine equipment, trolling motors, and off-grid systems. It can replace a traditional lead-acid battery.
When a charger is connected at 32°F, the battery enters heating mode automatically. Incoming charging power goes to heating instead of normal charging. Once the temperature rises above 41°F, heating stops and charging begins automatically.
A 100A BMS manages the battery during charging and discharge. It protects against electrical faults and abnormal temperatures. The battery uses Grade A LiFePO4 cells with passive cell balancing. An IP65-rated enclosure protects against dust and damp, and a built-in handle makes it easier to move. The Vatrer app shows real-time battery information on your phone.
