REC 2Q Master/Slave 48S BMS Kit

REC 2Q Master/Slave 48S BMS Kit

New for 2023 and now in stock!

We have assembled a near complete kit for your high capacity CANBus compatible 33S to 48S series battery system utilizing the all new 2Q series BMS, for use with voltages from 27V to 177V nominal(depending on chemistry) and pack sizes up to 600aH (and maybe a bit more) when matched cells are used

Includes:

  1. REC Master BMS
  2. 3 Element Temperature sensing harness
  3. 500A Current shunt and cable (200/500/1000 available upon request)
  4. 2 X REC 2Q 16S BMS
  5. 2 x 16S Cell wiring harnesses
  6. Current/Dual Temperature probe wiring harnesses
  7. Power and I/O wiring harness
  8. Wi-fi module and wiring harness

Just add cells, field wiring and relay/contactor!

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. 

Features include:

  • 5-16 cells connections (14 – 68 V system)

  • up to 4 digital temperature sensors DS18B20 per slave

  • single cell voltage measurement (0.1 – 5.0 V, resolution 1 mV)

  • single cell - under/over voltage protection

  • single cell internal resistance measurement

  • SOC and SOH calculation

  • over temperature protection

  • under temperature charging protection

  • 4 Ω passive cell balancing with temperature protection

  • shunt current measurement (resolution 19.5 mA @ ± 500 A)

  • two galvanically isolated user defined multi-purpose digital outputs

  • internal relay high current outputs for the main relay/contactors

  • galvanically isolated RS-485 communication (in and out port with enable)

  • CAN communication

  • error LED + buzzer indicator

  • Wi-Fi for changing the settings and data-logging 

  • Remote ON/OFF

Just select the Smart CANBus Inverters interface you need:
  1. REC BMS CAN protocol
  2. Victron
  3. SMA
  4. Solax
