REC BMS High Current 48V Master/Slave Kit

The REC BMS Master Slave system is an advanced battery management solution designed to optimize the performance and safety of battery packs in high capacity parallel pack applications, including electric vehicles, solar energy storage (ESS), and more. It consists of a master unit and one or more slave units, with a CANbus interface to most modern Smart Inverters and chargers. The master unit is responsible for overall system management, data collection, and communication with external devices. Each slave unit monitors individual cells or groups of cells within the battery pack, ensuring they operate within safe voltage, temperature, and current limits. This modular approach allows scalability and precision in managing large battery systems, enhancing longevity and efficiency.

We have assembled a near complete 48V Master/Slave parallel kit for your high current CANBus compatible series battery system utilizing the all new 2Q series BMS, for use with voltages from 12-64V nominal(depending on chemistry) and pack sizes up to 5,000aH when quality matched cells are used

Includes:

1. REC Master BMS
   
2. 500A Current shunts and cable (200/1000A available upon request)
3. REC 2Q 16S BMS slaves
   
4. 16S Cell wiring connector kits (complete harness kits also available)
   
5. Current/Temperature probe wiring harnesses (4 temp sensor harness optional)
   
6. Power and I/O wiring harness
7. Wi-fi module and wiring harness
8. Slave Network cables

Just add cells, field wiring and relay/contactor(s) and if you want to connect to your Smart inverter or charger you will also need an SMA or Victron CANBus cable.

The REC 2Q is the next step in the REC BMS evolution.  Don't trust your safety and expensive battery system to a cheap or repurposed BMS!

This professional  grade system is customer configurable using the included Wifi module and pre-wired harnesses make the installation much faster.
