The stand-alone S-Series BMS controllers are typically used with low to medium voltage battery packs for mobile applications, small passenger vehicles, industrial applications, and backup power. An optional upgrade for ground fault detection is available. Our S-Series and X-Series controllers are highly configurable and can be adapted for many different application.

Controller	Voltage	# of Cells
S1	up to 55	4-12
S2	up to 110	up to 24
S3	up to 165	up to 36
S4	up to 220	up to 48

Our X-Series controllers may be more suitable for battery packs over 220 V or with more than 48 cells.
Our T-Series controllers are more suitable for low-voltage backup battery systems.
