VOLTHIUM LITHIUM 24V 100Ah Lithium Battery with Dual Self Heating and Advanced BMS. Deep Cycle Lithium Battery for Off Grid Solar Systems or 24V Trolling Motors


Volthium’s 24V100AH LiFePO4 ABS battery in 4D format is manufactured specifically for off grid house, cottage and cabins.

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

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 extend 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.

This new generation of batteries is also equipped with a stainless steel 304 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 picked up 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 -25 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.

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.
* Caution, 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 -25 only.

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

Average operation beyond 6000 cycles.
