GCE high voltage BMS products pictures:

RBMS(master BMS) it's GCE main control box. RBMS is consist of main control PCB, relays/contactors, charge and discharge current detecting euquipments, DC power, breakers, communication rs485, CAN TCPIP and other interfaces and connectors.

BMU(slave BMS) has 8S, 12S-16S, 17S-24S three types of bmu. you can make any types of battery packs according to your cell capacity , weight, and size as basic modules.

SBMS (Stack BMS), stack means 2 or more battery racks in parallel, then SBMS is necessary, because you need to make all the racks in parallel and get battery health information from each cell, SBMS has a 7 inch touch screen ,it's enough to display all information.
