REC 2Q BMS Wiring Harness: Precision Connectivity for Advanced Battery Management

Engineered for Seamless Integration with REC 2Q BMS Systems

The REC 2Q BMS wiring harness is a purpose-built cable assembly designed to connect the REC 2Q Battery Management System to your lithium battery bank with accuracy and reliability. This harness eliminates the guesswork and potential faults of generic wiring, providing labelled, pre-configured connections that streamline installation and enhance system integrity. Whether you are commissioning a new off-grid energy storage system, upgrading an existing setup, or replacing a damaged harness, this assembly ensures your BMS communicates effectively with cells, sensors, and external devices.

In complex DC power systems, signal integrity is critical. Poor-quality or improvised wiring can introduce noise, voltage drops, and intermittent connections that compromise battery monitoring and protection. The REC 2Q harness uses high-quality connectors and clearly identified conductors to maintain stable data transmission and accurate cell voltage readings, reducing the risk of BMS faults and system downtime.

Key Features at a Glance

  • Pre-assembled connectors for all five 2Q BMS ports, eliminating wiring errors
  • Labelled cell sense wires for 4 to 16 lithium cells, simplifying termination
  • Integrated CAN Bus lead with Weipu SP13 connector for Victron and other compatible devices
  • Dual DS18B20 digital temperature sensors for precise thermal monitoring
  • Shunt sense cable with 4mm lugs for accurate current measurement
  • Remote ON/OFF switch and configurable I/O wires for external control and alarms
  • Spare RS485 connector included for custom industrial interfaces

Complete Connectivity for Your BMS

This harness covers every interface on the REC 2Q BMS, ensuring you have the right connections from the start. The CELLS connector provides 17 labelled wires (Cell 1- to Cell 16+) plus Pack - and Pack + power supply leads, all cut to a 2-metre length for flexible routing within your battery enclosure. A dedicated pre-charge wire is also included, supporting safe system startup without the need for additional components.

The Isens Tsens connector features two DS18B20 digital temperature sensors and a shunt sense cable terminated with 4mm lugs. The temperature sensors allow the BMS to monitor cell or ambient temperatures at two points, enabling precise thermal management and protection. The shunt sense cable connects directly to a battery shunt, with the "+" lug clearly marked for the battery side, ensuring correct polarity and reliable current data.

CAN Bus and Communication Integration

The RS485 CAN T Cp connector includes a 0.5-metre CAN Bus lead terminated with a Weipu SP13 circular connector. This interface is commonly used to link the BMS with Victron GX devices, inverters, and other CAN-enabled equipment. A termination jumper is pre-installed on the "T" pins, simplifying network setup. For RS485 communication, the harness provides a spare connector with pins on the RS485-0 port, allowing installers to wire a custom interface for industrial RS485 networks without sourcing proprietary plugs.

Note: While the CAN lead uses a Weipu SP13 connector, many inverters and controllers require an RJ45 connection. A separate CAN Bus adapter cable (available from REC) may be needed to match your specific device pinout, as there is no universal standard for CAN RJ45 wiring.

Control and Monitoring Flexibility

The I/O connector brings out essential control and monitoring signals on a 1-metre cable. It includes a remote ON/OFF micro rocker switch, allowing convenient manual control of the BMS without accessing the unit directly. Additional labelled wires—OPTO RELAY IN, OPTO RELAY OUT, OC 1-, OC 1+, OC 2-, OC 2+—provide open-collector outputs and an opto-isolated relay interface for external alarms, contactors, or automation systems. This flexibility supports integration into larger energy management setups, from marine and RV applications to off-grid residential systems.

Built for Demanding Environments

All connectors are genuine TE Connectivity (AMP) parts, selected for their proven reliability in high-vibration and temperature-cycling conditions. The use of locking connectors prevents accidental disconnection, while the labelled wires reduce installation time and the potential for miswiring. This harness is suitable for use in mobile, marine, and stationary energy storage applications where dependable BMS operation is essential for battery safety and longevity.

Why Choose the REC 2Q Wiring Harness?

Using the correct wiring harness is a critical step in ensuring your REC 2Q BMS performs as designed. Generic or field-assembled cables often lack the proper connector housings, pin assignments, and wire gauges, leading to unreliable connections and potential damage to the BMS or battery cells. This harness is built to REC's specifications, providing a plug-and-play solution that protects your investment and reduces commissioning time.

By maintaining accurate cell voltage sensing, stable communication, and reliable temperature and current monitoring, this harness helps the BMS protect your lithium cells from over-voltage, under-voltage, over-temperature, and over-current conditions. It is an essential component for anyone serious about battery performance and safety.

Great Value for a Good Moisturizer (5- Stars)
Size: 3 Fl Oz (Pack of 1)
This moisturizer contains nothing fancy — and that’s the whole point. The ingredients are few but effective, with several ceramides and hyaluronic acid for deep and long-lasting hydration. Best of all, it contains no silicones or parabens. Because it’s noncomedogenic, it doesn’t cause breakouts from clogged pores. Since I have sensitive skin, all of the above are critical for my skin care routine. It’s about as simple and as effective as a cream can get. Because of that, it doesn’t contains any sunscreen, retinol, or other anti-wrinkle components.

Medium weight minimal ingredient moisturizer!
Size: 3 Fl Oz (Pack of 1)
As with another review, I’m looking for a replacement/dupe for Eucerin Urea Repair face moisturizer which is 5% urea Skin concerns: dry rosacea, mid-40s, arid climate with 4 seasons, winters are cold and snowy and summers are 90°+ for most. This is a medium-weight moisturizer that I consider not greasy at all. It is not as hydrating as I need it to be for my dry skin type with rosacea. Thickness wise I say it is similar to a standard facial sunscreen. It does last overnight, in the morning I can still feel it in some areas. I will try increasing how much I apply in order to see if it helps with how much staying power it has. This may increase the hydration it provides and I will update my review to report back. I had a very mild stinging sensation but my rosacea is struggling since moving to a dry climate. Once I repair my skin barrier a bit, I fully expect this will cease. Due to this, I’m not going to get my husband to try it, he has constantly broken skin from severe eczema and stinging is something that makes him not use moisturizers. It’s a battle! For people in more humid climates this may be a more effective moisturizer, or those with less-dry skin than me. I never have flakes so this wasn’t a parameter for me. There is no tint. I’m not sure about white cast so I can’t rate it for skin tone. But I don’t feel there would be, this seems translucent unless you really go in with it. For me it is reasonably effective. It’s probably a good day moisturizer and I expect it plays well with sunscreen, though I would definitely let it absorb or dry down. Which is pretty standard for daytime skin care. There is a slight grippy feeling when applying, but this dissipates like the Eucerin Urea Repair does. This is not, for me, a replacement or dupe for Eucerin Urea Repair. It is a great value for the price! Overall for someone with skin like mine I rate it a very solid 4/5. I would likely purchase again for a lightweight moisturizer as a more affordable substitute for Beauty Of Joseon Dynasty Cream for day. Though this does not give me the “bounce” that does. Alas. Updated to add: I tried increasing the amount I apply, and that eliminated any grippy feeling when applying. I now apply both day and night and this has helped repair my barrier enough it doesn’t sting when I apply this. I still have a way to go before I can return to using my sunscreen, but I do work in a building with no windows so the few minutes I am outside, it’s okay if I go without. If I apply this to my eyes, it doesn’t sting them, which is great, my eyes are extremely sensitive and I hesitated, but it works out just fine. It isn’t thick enough to cause whiteheads to form on my lids, unlike some balm-type moisturizers (LRP!) and even unfortunately Bioderma Sensibio Eye+ I have noticed the backs of my hands are improved as I wipe off excess onto the backs of my hands and into my cuticles. I was genuinely surprised by this, it’s not like I don’t wash my hands. I wasn’t expecting it to have any effect, but the stinging scaley hands are gone, now my hands just feel normal, even after wearing wool fingerless gloves all day at work. I will continue to use this product and will repurchase even after my financial situation improves.

My rosacea approves
Size: 3 Fl Oz (Pack of 1)
I have Rosacea, dry, sensitive, reactive skin and perimenopausal skin. My rosacea products tends to dry my already dry skin and this has been been a great moisturizer. My skin looks dewy, dullness and dryness have improved in just 2 days; I haven't reacted with sting and redness like I usually do and when I wake up I still have a dewy not greasy face even though I sleep on my sides and toss and turn all night. Definitely going to buy again since the bottle size is good, a lil goes a long way and does not make my face react like the CeraVe.

This stuff works nicely
Size: 3 Fl Oz (Pack of 1)
So I don't typically leave reviews, but I feel like this lotion has been fantastic to me. I typically don't use lotion because I hate the feel, but my face really needed it. I have dry/oily skin. My skin gets gross and flaky, yet it's pretty oily. I've always dealt with it. I decided to go ahead and buy this stuff because I couldn't take my dry skin. It helps soooo much and you barely need any. I use a dime sized amount and really focus on my problem areas. It lasts all day, not too thick and not too watery. Not greasy at all for me and soaks in very nicely. Again, it lasts all day and I don't need touch ups, even on bad skin days. I don't ever break out and it's never clogged my pores, but to be fair I've never really had skin that's broken out much before. The one thing I did notice, before using this stuff I started noticing more fine lines around my eyes/forehead. I've been using this stuff for about a year and you can barely see them anymore. I have haven't changed my diet, it's pretty atrocious honestly, so I really feel this lotion has worked wonders on its own. Also I still have a decent amount left in the bottle and I bought it almost a year ago. I'm going to try their body lotion next. Hope this helps, or at least give it a whirl!
