The Epoch 12V 334Ah Essential delivers 334Ah and 4.28 kWh of reliable LiFePO4 storage. A practical choice for RVs, boats, and off-grid installations if you want plenty of usable energy without the weight and maintenance of a traditional lead-acid battery.

• 4.28 kWh usable LiFePO4 storage: a maintenance-free energy source with a nominal voltage of 12.8V, designed for RVs, boats, and off-grid installations.
• Power when needed: up to 300A continuous and 600A for 10 seconds for short peak loads.
• Expandable within clear limits: Series connection is not permitted. For additional capacity, up to 16 identical batteries can be connected in parallel.
• Smart BMS: protects against overcharging, deep discharge, overcurrent, short circuit, and excessively high or low temperatures.
• Monitoring and communication: Bluetooth via the Epoch app for charge status, voltage, current, and temperature, CAN bus communication with suitable Victron GX systems.
• Ready for practical use: The metal IP21 casing belongs in a dry, protected indoor setup; this model is not intended for a wet battery compartment. The internal heating enables safe charging at low ambient temperatures.
• Active cell balancing: the built-in 2A active balancer helps correct voltage differences between cells during use.
• 4,500+ charge cycles and 11-year manufacturer's warranty: made for years of cyclic use, without water top-ups, acid, or regular battery maintenance.

Please note: this is a deep-cycle battery for household and auxiliary power supply. Do not use it as a starter battery unless Epoch has explicitly approved the specific application.
