REC 2Q BMS 16S Electronic Unit: Advanced Battery Management for 4 to 16 Lithium Cells
Precision Control for 12V to 48V Lithium Battery Systems
The REC 2Q BMS 16S Electronic Unit delivers professional-grade battery management for lithium battery packs with 4 to 16 cells in series. Designed and manufactured in Europe, this BMS provides comprehensive protection, monitoring, and communication for 12V, 24V, 36V, and 48V nominal systems, making it suitable for marine, off-grid, electric vehicle, and industrial applications where reliability is critical.
Unlike generic BMS units that offer limited configurability, the REC 2Q provides galvanically isolated communication interfaces, high-accuracy measurements, and flexible integration options. It addresses common risks such as cell imbalance, over-discharge, and thermal runaway by combining precise monitoring with programmable protection thresholds.
Key Features
- High-accuracy cell monitoring with ±1 mV voltage resolution for precise state-of-charge (SOC) and state-of-health (SOH) calculations
- 18-bit shunt current measurement with 19.5 mA resolution at ±500 A for accurate energy tracking and Wh counting
- Galvanically isolated RS-485 and CAN Bus for noise-immune communication with inverters, chargers, and monitoring systems
- Integrated 25 Ω pre-charge circuit with adjustable delay to protect contactors and extend system life
- Passive cell balancing (4 Ω) with temperature protection to maintain pack health
- Remote ON/OFF and Control Pilot (CP) for EVSE for seamless integration with electric vehicle supply equipment
- Real-time clock with error log storing the last 7 faults for simplified diagnostics
- Compliant with ISO16315, ISO10133, EN61558-1, EN61558-2, and EN50498 for marine and industrial safety
Flexible Communication and Integration
The REC 2Q BMS supports CAN Bus protocols for managed batteries, with pre-configured options for Victron, SMA, Solax, Studer Innotec, Growatt, Solis, Pylontech, Deye, TBB Power, TC Charger, Zivan, and custom configurations. Bitrates from 100 kbit/s to 1 Mbit/s and both 11-bit and 29-bit IDs are supported. The galvanically isolated RS-485 interface enables direct connection to the optional REC Wi-Fi unit for wireless configuration and data logging, or integration into home automation and industrial control systems.
Built for Demanding Environments
With an operating temperature range of -20 °C to 70 °C and IP32 protection, the REC 2Q BMS is engineered for reliability in mobile and stationary installations. The compact 190 x 98.4 x 38 mm housing and 4.5 mm mounting holes allow straightforward installation in confined spaces. The unit's low power consumption (180–190 mW during operation at 48V) minimises parasitic drain on the battery pack.
Applications
- Marine lithium battery systems requiring ISO compliance
- Off-grid solar storage with 12V to 48V battery banks
- Electric vehicle conversions and EVSE integration
- Industrial backup power and remote monitoring
- Custom battery builds needing flexible communication protocols
Whether you are upgrading an existing lithium battery system or building a new pack from scratch, the REC 2Q BMS 16S Electronic Unit provides the precision and adaptability needed for safe, long-lasting performance.
Add the REC 2Q BMS to your battery system today and gain complete control over your lithium cells with European-engineered reliability.
