The Epoch 12V 334Ah MC Essential Series LiFePO4 Battery is a high-output 4.28kWh deep-cycle battery with a 300A continuous BMS (600A peak for 10 seconds) – enough to run properly designed 3,000W+ inverter systems, air conditioning and galley loads from a single 12V battery.
Built-in Victron communications let the bank report to compatible Victron systems such as the Cerbo GX, while Bluetooth monitoring, internal heating for cold-weather charging and 2A active cell balancing keep the battery healthy over its 4,500+ cycle life. Its metal IP21 case is intended for dry, protected interior spaces – not exposed or wet battery compartments.
