REC BMS 2Q series 16s BMS

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 BMS now supports 3 Outputs, 2 of which are customer configurable using the Wifi module.  Prewired harnesses make the installation much faster.  A new processor and more memory allow for more future control functionality and now includes a built in Precharge circuit. As part of the new "Smart" charging and control philosophy it supports many of the popular CANBus inverter and charger interfaces as well as EVSE for EV charger interfaces.

Includes single temperature probe (expandable up to 4 probes with optional DS18B20 sensors) and current shunt wiring harness.

Both a basic connector kit and prewired set of cables are available separately:  https://ogm-energy.com/products/rec-2q-wiring-harness-kit
