The S3 BMS controller is designed for low to medium voltage lithium-ion battery systems and supports 3 separate cell banks. Each cell bank can have 4-12 cells in series, for a total of 12-36 cells.

Originally developed for use in electric vehicles, the S3 controller’s standalone design is highly configurable for many different applications. Features include built in relay control, an isolated CAN bus and isolated RS-232 for communications, 6 configurable digital or analog inputs/outputs, redundant hardware safety disconnect, voltage and temperature monitoring for every lithium-ion cell, and a battery output current sensor.
