S1 BMS Controller

The S1 BMS controller is designed for low to medium voltage lithium-ion battery systems, and supports 1 cell bank with 4-12 cells in series.

Originally developed for use in electric vehicles, the S1 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.

There is an S-Series model comparison on the S-Series page. To read more about this model, download the S-Series data sheet.
