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.

Great buy
Color: Black, Size: 4 Panel-88''
This room divider is exactly what I needed. When you have 2 kids sharing a room and don’t want to spend a lot of money to divide their space this is what you can use. Believe it or not they are much happier now. This came in a small box which scared me but once I was able to get this up I was very pleased. It was easy to put together. The fabric is pretty good quality, it’s stable and stands up fine. Good value and worth it to have peace and quiet in the house.

Junk
Color: Black, Size: 4 Panel-88'', Color: Black, Size: 4 Panel-88''
Horrible. The parts are not right. It won’t fit together or disassemble and can’t return it like this. Parts won’t fit properly and missing holes for screws. Also, can’t get through to a person for any assistance. Picture shows the hole and then the lack of a hole where a screw belongs.

Good product, poor directions.
Color: Black, Size: B-88''W-4 Panel
The quality of the product was better than most at this price. The directions could have been much better even though I have an engineering background.

Nice partition for my basement
Color: Beige, Size: B-102''-3 Panel
This 3-panel room divider showed up well-packaged with all the parts and even a little tool for putting it together. The instructions were easy to follow, and while one person can definitely assemble it, having two makes it quicker and less frustrating. It does exactly what I needed—gives quick, easy coverage in an open area. I'm using it in my basement to hide the furnace and water heater, and it works great for that. It looks nice overall, but I picked the beige fabric (which is really more of a tan), and the black frame makes it stand out more than I’d like. A white or lighter frame would’ve blended better. Not sure that I would use it anywhere besides the basement It’s lightweight and pretty sturdy. The wheels make it easy to move, but it does get a bit wobbly, and the panel clips need to be readjusted every time you roll it somewhere new. Still, for the price, it’s a solid buy. I’m happy with it and planning to order another one.

Fantastic
Color: Beige, Size: A-132''W-6 Panel
I am perennially in the process of rearranging, reorganizing, getting ready for yard sales, changing the functions of various rooms, moving everything out of a room to do a deep clean, etc, which means that there is always SOME part of my house, if not the entire thing, that is a disaster zone. Having someone knock on my door triggers a "duck and cover" reflex because it's so embarrassing for anyone to see that I live like this. (I *feel* like I don't, really, because I know that all the various stages are all temporary, but when there's always something temporary going on, it might as well be permanent, you know?) So THANK HEAVENS for a room divider that is not only large enough to divide my uncomfortably long den in half the long way so I can shove all the messy parts up against the back wall -- that is not only simple and attractive and neutral and (this is important) NOT BLACK because I have multiple pets and anything black in this house will be pet-hair-colored within 20 seconds -- that not only has **SIX** panels for lots of options of how I want to divide the space/s -- but is also on WHEELS. Someone out there really does love me, it's true! The panels are stable *enough* - I'm not going to lie and say that nothing is going to knock them over, because I have some balance issues, and I also have cats, and both of those circumstances has resulted in a mess on at least one occasion. But in the cats' defense, they've never dealt with a room partition that didn't hang from the ceiling before; and in my defense, I just grabbed the first thing I could reach on the way down. Not the product's fault in either case. Assembly was a little dicey as I am currently in **bilateral** (oh yes, that's fun) wrist braces, so I had to give up until I had help. But I think if you're able-bodied, you shouldn't have any difficulty. The only down side is, now that I've hidden away all the mess so I can break out the holiday decorations, you know what happens next, right?? That's right... the PERMA-MESS ZONE. Oh no. Oh well.
