Our expandable X-Series BMS controllers are typically used with medium to high voltage battery packs for mobile applications, full electric and hybrid electric vehicles (including city buses), and industrial machines. The X-Series’ patent-pending design includes features to increase safety and intelligently manage inter-controller communications. Our S-Series and X-Series controllers are highly configurable and can be adapted for many different applications.

Controller	#	Voltage
X-BCU (master)	1-20 X-MCUP controllers	up to 1000
X-MCUP controller	4-12 cells	up to 55
X-Series BMS Total	up to 20 X-MCUP, 240 cells	up to 1000

Our standalone S-Series controllers may be more suitable for battery packs under 220 V with 48 cells or fewer.
Our T-Series controllers are more suitable for low-voltage backup battery systems.
