The Vatrer 12V 300Ah is a dual-purpose LiFePO4 marine battery that claims 1500 CCA for engine cranking plus 300Ah (3840Wh) of deep-cycle capacity for house loads. A built-in 200A BMS handles overcharge, over-discharge, over-current, short circuit and temperature protection, and blocks charging below 32°F. Bluetooth lets you watch state of charge and cell data from a phone. It suits boaters and RVers who want one battery for starting and house power and who accept the cold-charging cutoff; against lead-acid it is far lighter and lasts more cycles, but LiFePO4 needs a compatible charger and costs more upfront.

Owner feedback on Vatrer's large LiFePO4 marine batteries is limited but generally positive, with buyers citing strong cranking and steady house power. Complaints center on cold-weather charging limits and the need for the right charger.
This is a pack of four Vatrer 12V 300Ah LiFePO4 dual-purpose marine batteries. Each battery combines 1500 CCA starting power with 300Ah of deep-cycle capacity, or 3840Wh. One battery can start the engine and also run onboard loads such as fish finders, pumps, lighting, navigation, refrigeration and inverter-powered equipment.
Each battery has a built-in 200A BMS that manages overcharge, over-discharge, over-current, short-circuit and temperature conditions. Charging stops below 32°F and resumes automatically when the battery reaches a safe charging temperature. The Vatrer app connects over Bluetooth and shows state of charge, voltage, current, temperature, operating status and cell information. The Grade A LiFePO4 cells support more than 5,000 cycles.
Each battery can be charged with a LiFePO4 charger at the dock, through solar with an MPPT controller, or from a generator with a DC-to-DC charger. Batteries can be combined in series and parallel, up to a full configuration of 61.44kWh. Each battery weighs 55.23 lbs and measures 15.16 × 7.56 × 9.76 inches.
