Thanks to its modular design, the Battery-Box HV does not just increase in voltage, but also in capacity. If more power or higher capacity are required, the Battery Box HV Tower can be expanded at any time. The B-Plus HV modules have a capacity of 1.28 kWh and a voltage of 51.2 volts. One Battery Box HV Tower can include between 5 and 9 modules in series. Resulting in a voltage level between 200 Volt and 500 Volt.

The Battery-Box LV is a 48V battery with a flexible and modular cable-less design. A Battey-Box LV contains up to 4 battery modules B-PlusL3.5 in parallel and achieves capacities between 3.5 and 14.0 kWh (usable). By connecting up to 12 Battery Box LV in parallel you can reach a maximum capacity of 42.0 kWh.

The building blocks for a Battery-Box system are the B-plus 2.5 (2.5kw/2.56kwh) or the Battery-Box 13.8 (12.8kw/13.8kwh). You can parallel up to 32 units to reach 405kw/441kwh.
