REC Q Series BMS 16S Slave 12V


Slave unit 12V+ REC BMS Q series with integrated CAN communication protocol can manage from 4 to 16 cells (in series) used where a redundant system with several packs is required, as part of a Master/Slave configuration network. It is also compatible with Victron Cerbo installations for integration in PV systems.

Available on backorder | 2-4 weeks


BMS for 12V+ systems, WS500 compatible.  Special order from Head Office.

For use in 12V systems that require redundancy and connection with the Master Controller

Includes a single temperature sensor cable and current shunt pigtail with connectors
(Multiple QBMS units can be combined with the
REC Q Master for use in higher voltage systems).
