BMS201

Name: BMS201
SKU: BMS201
Availability: InStock

BMS201 is an all-in-one single-board battery management system with integrated 100 A MOSFET contactors and current sensing for 24-36 V batteries up to 200 Ah. It monitors every series-connected cell, provides passive balancing, and opens the power circuit in fault conditions through a solid-state contactor. Data and commands are exchanged over CAN, USB, or optional wireless interfaces.
