REC Active BMS Kit

Near complete REC Active 12V BMS kit.  Just add a safety relay/contactor and field wiring.

Kit includes the custom wiring harness with cell & relay wires, CAN and RS485 cables, temp. sensor, and remote ON/OFF switch as well as the Wi-Fi Module for configuration, monitoring and logging, all from a standard browser such as Safari, Chrome, Edge, etc.

Designed to provide unsurpassed battery
management in 12 volt systems, the REC Active BMS delivers 2A
cell equalizing with active balancing and synchronous flyback bidirectional energy transfer from cell to pack and pack to cell.

Suitable for (1-4)P4S packs of up to 1,000 Ah, and even larger for well behaved quality matched cells.  (Unmatched or B grade cells may limit pack size, due to continuous balancing needs)

2A cell equalizing with active balancing with synchronous flyback bi-directional energy transfer: cell to pack and pack to cell two fused relay outputs with NO and NC pins two fused galvanically isolated/non-isolated digital outputs with PWM option

It is also a member of the "Smart" line of DC power products that integrate with the Victron Cerbo/Venus as well as the Wakespeed WS500 on the CANBus network. 

Kit includes:

1. REC Active 12V Smart BMS
2. REC Active Prewired harness with Amp connector, temperature sensor and remote On/Off switch
3. REC Wifi module
4. Victron interface cable
5. 500A/50mv current shunt

For systems with large inductive loads such as inverters you may want to include a REC PreCharge module to reduce arcing and EMI during startup.
