LiFePO4 12V 314Ah energy bank for campers, energy storage, UPS

Universal 12V 4S LiFePO4 314Ah battery with cell compression.

A powerful power source for campers, trailers, yachts.

Made in Poland.

Battery design highlighted at ENEX 2025

• Ready-to-use battery built on the basis of a housing that is Onvolt’s own design. This is the most compact device of this capacity available on the market.
• The battery is perfect as a power source for campers, trailers, yachts, as a battery for UPS systems as well as for the needs of households and summer houses.
• The battery was manufactured using the highest quality LiFePO4 EVE 314Ah cells (tested capacity> 330Ah, service life above 8000 cycles, Grade A+), a 200A BMS system from JK with an active balancer and a BT module.
• The clear and legible LCD display allows you to constantly monitor operating parameters (voltage, current) and battery charge status.
• Control of all battery operating parameters (including the voltage of individual cells) is easily accessible via a mobile application (Bluetooth connection).
• The built-in BMS system protects the cells against exceeding all critical parameters (charge and discharge voltage, temperature range, charge and discharge current, cell voltage difference) and enables the equalization of cell parameters thanks to the built-in active balancer.
• The high-quality 300A rotary switch provides additional protection when the battery is not in use.
• Dual 2x200A M8 current connectors enable convenient connection of receivers.
• The housing design uses a unique cell compression system that provides the right parameters for proper cell compression and their efficient operation for many years. This is probably the only battery of this size on the market with a cell compression system.
• The battery can be easily carried thanks to the convenient handles mounted on both sides. The use of appropriate feet and optional mounting brackets allows the battery to be freely positioned anywhere, and in the case of applications in all types of vehicles, to be attached to the ground.
• The aluminum housing presents high aesthetic values ​​and is covered with a durable and resistant powder paint providing excellent anti-corrosion protection.

IMPORTANT:

All LIFePO4 batteries should be charged using a dedicated device (charger, inverter). Charging from an alternator is possible using a lithium battery separator.
