BMS Mini

Centralized BMS for 24-72V batteries

Mini is a full-featured centralized BMS for high-capacity lithium-ion batteries. It has many communication interfaces, an ability to collect information during the entire battery lifetime and an integrated DC/DC converter.

BMS Mini can manage a battery consisting of 6 to 18 cells.
