Volthium's 48V 100AH ABS battery in 8D format

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

Self-heating version (Dual Technology)

These batteries have the particularity to have an accessible and reserved chamber for the BMS. This makes them repairable in case of need, and allows to prolong the life of the cells by limiting the transmission of heat to them. In addition, a private chamber increases the usable temperature range of these batteries.

In addition, this lithium battery has an integrated cooling system that allows the heat to escape from the battery via its conductive aluminum plate. 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 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 environment (on their VE.CAN protocol). To do this, get the Volthium HUB accessory, another exclusive development of ours.

In addition, the RJ45 connector allows you to add the Volthium bluetooth transmitter, which can handle up to 4 batteries when paired with the HUB.

Not only is this LiFePO4 battery resistant to vibrations, but it has a discharge range superior to the competition. In fact, this battery can be discharged down to -30 degrees, instead of -20 degrees for the competition. And if you choose the self-heating option, it can be recharged down to -40 degrees. This innovation is possible because the cells in Volthium batteries come from the automotive industry.

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

Average operation beyond 6000 cycles.
