REC 2Q 4 Probe Temperature Sensor Harness

Ordering is ez-pee-ze, nice follow up email with links to important docs, order arrived on time. OGM has been very consistent over the past 2-3 years that I have been working with Rick. I am very satisfied that the order is processed right away and the shipping times are spot on with minimal cost. (I paid a little bit to have the order shipped using a faster method) 5 Stars… again.

I was managing a self-made14S6P 51V battery pack with a Batrium Watchmon for several years. My configuration also includes a 58V 160A alternator that had a GenSun regulator that could only be managed with a relay-driven on/off state. The rest of my configuration consisted of a Victron Cerbo GX, a Victron Quattro 48-3000 and a Victron MPPT 100/20-48.

I wanted more control over the alternator so I ordered a Wakespeed WS500 and a REC 2Q BMS kit. The installation went well and the integration between the Cerbo GX, REC 2Q BMS and Wakespeed WS500 has been flawless. The installation kit included everything necessary to professionally connect the REC 2Q to the battery pack, sensors and relays. You may want to add the CAN bus cables that connect the REC BMS 2Q and the Wakespeed WS500 to the Victron Cerbo GX. You may also find that you want to add a few more of the temperature sensors. I reached out to OGM for support at a couple of points during the installation. Their responses were prompt and helpful. I’ll look forward to working with them again.

Ordered a rec 2q kit and the overall experience was super. First i received a wrong canbus cable but that was resolved immediately. Can advise OGM for the excellent service.

REC BMS 2Q series 16s BMS

This spring, during some physical maintenance, my REC 1Q based system went hard down with an error 15 fault. Rick owned the recovery from first contact (in spite of the fact that this was objectively my fault).

Responsive: Same-day email replies and a quick follow-up call to confirm diagnosis and next steps.
Expert troubleshooting: Identified a likely cell-tap issue, shared clear upgrade guidance, and produced a 1Q→2Q wiring cross-reference to de-risk the retrofit.
Deadline support: Built a complete parts list and coordinated an expedited UPS shipment to meet a tight install window.

Result: minimal downtime, smooth 2Q backfit, and a partner I trust for future work. Strongly recommend OGM for sourcing REC and Wakespeed equipment.

This is the 2nd time in 4 years that Rick helped me recover from a major system failure that left us powerless and under a tight recovery timeline. His level of support stands out dramatically compared to experiences we've had with other suppliers of equipment in our system.

Rick was super helpful in answering all my detailed questions as we worked through what was mostly user error and clarifying documentation. Could not be happier and will get my wakespeed from OGM when the time comes!

All l can say is that after l have tried multiple of the other BMS that are much cheaper is that they all are in a box beside my bench..l will say that as someone that has done different things most of my life l knew every time I was hooking up the other systems l was highly suspicious of the wiring quality and having messed with electrical systems I should have known better but it seemed they all were the same until I finally bit the bullet and ordered the Rec2Q and looking back if I would have done this in the beginning l would have had just one BMS system and the money I spent on the other ones would have bought the one I am using.. and not to mention the freedom to leave my house without worrying about it burning down..

I just wanted to let anyone else know that I first saw the Rec2Q BMS when I was first thinking about solar and since then I have tried many others trying to save a few dollars and I can say from my experience that once I saw first hand how a BMS actually has to do it's job that I stood no chance with what I was purchasing and if I would have followed my gut I would have been where I am now much sooner and the price of the other stuff I bought in between actually purchasing the Rec2Q l could have paid for the unit.. because it actually works right out of the box..l have 20 330w panels and 2 solar charge controllers and a10000w inverter with right now16 280 ah eve lfp cells and other than being a dummy as far as figuring out the WiFi absolutely no problems.. and after many days and nights of no sleep and constantly trying to speak different languages and time differences with the latter l am really impressed with my Rec BMS just the quality of the wiring alone at first feel let me know that I could have burnt everything l have worked for down if the others would have worked at all.. there was no way what I was purchasing before my Rec BMS unit would have done what it is.. Thank you guys for everything..

Good experience from ordering to receipt of products. Good communication throughout the process. Special thanks to Rick for complete and prompt answers to some questions I had. Will recommend OGM to others.

I bought the REC 2Q kit from OGM and had some issues with my marine offgrid BMS battery setup. I contacted OGM support via email and Rick was able to respond very quickly. He reviewed my situation and gave me instructions on what corrections were needed. The corrections were made and the BMS is now operating as it should. I would not hesitate to highly recommend the REC BMS and OGM for your Lifepo4 off grid installation.

Support team was able to trouble shoot an issue very quickly over email. Super impressed with the support I received.

Nice work - thanks again

OGM is fantastic and Rick is extremely helpful. This is my third REC BMS!

Amazing product & fantastic customer service from Rick @ REC NA / OGM.
Very happy customer!

After having built a lifepo4 battery with a mass produced JBD BMS, I knew I wanted something different when switching to EV. I had heard great things about REC from users of Electric Sailboats on Facebook. I wanted my BMS to be the best quality I could get.

The installation was very straightforward, and greatly simplified by the availability of prebuilt wiring harnesses. The features of the BMS are impressive - while I havent used it yet, the 2 opto outputs are very sophisticated in terms of software control, and I will surely find a use for them.

I'm working on using BMS CAN and fully integrating with Victron multiplus & cerboGX. The fact that Victron lists REC as a known-working integration gave me a lot of confidence in the solution.

I had sent emails (excessive emails!) to REC since January asking for details about the product and release date info. It's a great product, and I'm happy I waited for release.

OGM energy has been very responsive in answering inquiries, and shipped the product sooner than expected. Very pleased!

Rick was wonderful setting me up with parts for a project for a film studio. He was able to provide quick advice for a part that wasn't functioning as expected and recommended a replacement part quickly. I'm happy they are carrying the REC BMS and have them in stock! It's a very solid system that's easy to interface with!

Had to clarify a few things before we placed the order, Rick was very responsive and helpful. Will definitely buy again in the future.

Purchased REC 16s BMS from Off Grid Marine Energy systems and did not purchase the current sensor wiring harness, I emailed asking if it was meant to be included and they threw it in for free. When I had questions about shipment they were answered in a timely and polite manner.
