16S - BMU

BMS

Description

16S BMU is a distributed battery management system that is fully configurable, along with advanced safety features and estimation algorithms.

The 16S BMU can be integrated with a Contactor Control Unit for operating with Contactor based solution as well as with 100A/200A FET Control board for operating with FET based solution.

Supports up-to 16 cells in series and allows a continuous current of 200A. Designed for E-3W applications.
