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 a lot of usable energy without the weight and maintenance of a traditional lead-acid battery.

• 4.28 kWh usable LiFePO4 storage: a maintenance-free power source with a nominal voltage of 12.8V, tailored for RVs, boats, and off-grid installations.
• Power when needed: maximum 200A continuous and 400A for 3 seconds for short peak loads.
• Expandable within clear limits: Maximum 4 identical batteries in series or 16 in parallel, with identical cabling, appropriate fuses, and batteries of the same model and charge status.
• Smart BMS: protects against overcharging, deep discharge, overcurrent, short circuits, and excessively high or low temperatures.
• Monitoring and communication: Bluetooth via the Epoch app for charge status, voltage, current, and temperature.
• Ready for practical use: The IP54 housing is protected against dust and splashing water and should be placed in a dry, sheltered battery compartment. The internal heating allows safe charging at low outside temperatures.
• 4,000+ charge cycles and 6 years manufacturer's warranty: made for years of cyclic use, without water refilling, 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.
