Self-sufficient ESS lithium battery 51.2V - 125Ah - 6400Wh

With the self-sufficient ESS lithium battery 51.2V - 125Ah, we are completing our range of 48V storage systems.
This battery communicates directly with a Victron system (GX device) and has a high capacity per unit.

It does not require any further BMS wiring on a Victron system with a GX device.

A MultiPlus 48/5000 can be operated from one battery without any problems. In combination with a MultiPlus, a storage solution can be realized with only 2 main components. With solar panels and an Easysolar, a solar energy storage system can be realized with 3 main components.

In tiny houses, a reliable solar storage system can be realized with just a few components that fits into a small space.
Including feed-back into the public grid.


The battery is also suitable for use with electric boat drives. In parallel operation, a large storage system is created plug and play. Up to 24 units can be connected in parallel, up to 4 units can be stacked on top of each other.

The integrated 220W heater also allows operation / charging at low temperatures. Ideal for self-sufficient applications in the mountains or on vehicles.

Two potential-free contacts allow the switching of external charging units such as alternator regulators.

In order to ensure simple installation, we have opted for M8 connection terminals and not the BPC connectors as shown in the pictures.


The battery is housed in a steel casing and can therefore withstand harsh conditions. It can be securely mounted with the supplied frame and tension straps.

Scope of delivery:

- Lithium storage 51.2V - 125Ah
- 2m CAN BMS cable to Victron GX
- parallel cable 0.3m
- bottom / top frame with 2 tensioning straps per battery
- center frame for 2+ batteries

Example system with Easysolar:
