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.
