Build your REC Master/Slave BMS system as a kit and save 5% on all accessories!
Use the example diagram on the left as a guide to select the hardware you need for your application using the drop-down options below.
The Master brings it all together for larger systems and allows multiple Q or SI Series BMS’s to work together. Systems can be configured in either a series configuration to provide high voltage solutions or in parallel to provide multiple bank redundancy, or even series parallel for large high voltage systems. The Q Series BMS forms the foundation for higher voltage systems and includes features such as passive balancing, battery SOH and SOC and both RS485 and CANBus communications, with optional an LCD touchscreen display, and PC or WiFi options for configuration and monitoring.

REC Q Series BMS 16S Slave
$559.95Add to cartThe REC SI-Q BMS Slave is built on the same platform as the standalone SI-Q Series BMS, but works in conjunction with a REC Master Controller for larger systems configurations. It can be used in both parallel configurations where you have several cell packs working together and any one pack can be disabled without affecting the rest of the system. In series applications each slave controls up to 16 cells and up to a total of 15 packs, allowing system voltages in the 500-800 volts DC range.
