Li-ion NMC / LFP · 1P12S topology · VONSCH LOKO BMS

VONSCH LV modules are a range of prismatic Li-ion battery modules designed for the most demanding mobile industrial applications and stationary storage. The modules are built from high-quality CALB and REPT cells and are specifically designed for use with the VONSCH LOKO BMS system.

The 1P12S topology (12 cells in series) provides optimally low voltage for mobile applications. The LV01 and LV02 variants use NMC chemistry for maximum energy density, while the LV03 and LV04 variants use proven LFP (LiFePO4) chemistry with significantly longer cycle life and high safety.

All modules are certified per UN38.3 and comply with the EMC 2014/30/EU directive and IEC 61000 standards, making them suitable for deployment in regulated mining and industrial environments. The LV modules are the basic building block of the NEXISTORAGE R18 battery rack.
