Volthium's 12V400AH LiFePO4 ABS battery in 8D format is manufactured specifically for boats, sailboats, motorized vehicles and industrial applications.

The battery is designed for energy storage banks ranging from 5kWh to 20 kWh.


This lithium battery has an integrated cooling system that allows the heat to escape from the battery via its conductive aluminum plate. Once again, the heat sink further increases the usable temperature range,
while promoting better performance of the integrated BMS. In addition, an additional cooling system can be attached.
Another Volthium exclusivity.

This new generation of batteries is also equipped with a stainless steel 304 UL button, which allows to deactivate the discharge, while leaving the recharge authorized. Extremely, practical when the customer wants to leave the batteries connected to the solar system during storage, while eliminating the fear that they will be flattened by parasitic discharges.

This brand new battery, whose casing is exclusive to Volthium has 2x RJ45 ports, whose pins are gold plated, allowing communication on the RS485 protocol. This connector is also used to transmit the internal information of the batteries to the Victron Venus OS environment (on their VE.CAN protocol).

Exclusive Double Self-Heating Technology

The battery is equipped with two internal heating systems. The traditional intelligent system is activated when you apply a recharge to the battery when it is below zero. The second system, called manual, is activated when you apply a voltage to the positive H+ connector (M6) of the battery. This heating system, called manual, is not automated. If you connect the positive terminal of the battery (M8) to the H+ connector (M6) of the battery with a small piece of cable, it will be triggered using the energy of the battery.
* Attention, it is necessary to use a timer to avoid forgetting the heating in function
* The manual heating system is reserved for professionals and works down to -30 only.

10 years warranty, useful life around 15 years and more.

Average operation beyond 6000 cycles.
