REC BMS Replacement Current Shunt cable for Active and 2Q BMS

REC BMS 2Q series 16s BMS

I installed last year a wakespeed 500 together with a Vitron Cerbo GX on my 24 Volt system, which includes solar cells regulated by Victron Smart solar MPPT. Consumption is measured by Victron Smart shunt. It all works great and leave the batteries (LiFe) full and the solar cells do not any longer prevent the generator from charging. I am now doing the same with my 12 Volt system.

Fast delivery and good price.
Thank you.

Really appreciate Rick's follow-up and resolution to a shipping issue

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.

Much easier to configure and monitor

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!

I build a system with 1 Master and 5x 2Q Slaves, about 71Kw, hooked up to a Victron system and powering our off-grid house. OGM was quick to ship, and fully supported me when I had minor setup issues. Rick was incredibly knowledgeable and helpful and I highly recommend purchasing from OGM! I'll be back for more purchases shortly when I expand my system :)

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..

Great price and customer service answered questions before I bought it. Great company to do Business with!

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..

Great products and even better customer service. I do miss the telephone number for contact but understand the need for email contact.

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 must just comment on the level of support I have received since buying the WS500 4 years ago. Well in truth it’s been simply amazing as I am not a professional I have had to ask many basic questions and the patience and simple explanations I have received have seen me through some complex processes that I could not have completed had I not received such guidance. I have also received guidance as to what I did need contrary to what I thought I might need. I have nothing but good to say as many companies just cut and run once they have received your money but OGM walks with you until you reach your objective.

Off Grid and Marine Energy had a very nice sale on the Tyco 500A contactor for use with our REC BMS on our large LiFePO4 house bank - it will be perfect for our setup.

Absolutely amazing product support from Rick Bell. I bought my WS500 units nearly five years ago but due to a retiring job involving a lot of Victron and Lithium I had to seek some advice regarding connection issues and Rick Bell was both patient and informative…….amazing. I am very pleased with the response and thank you Rick and Wakespeed 🙏

Great communication, prices and support. If OGME has what I need, I’ll definitely be buying it from them again!

Fast and responsive ! My order was delivered to Europe in less than a week. Great service.

I actually priced out the Mate-N-Lok connector housings and the required number of crimp terminals from Digikey, and this kit is cheaper! Not to mention saving you the time and hassle of picking out each part number individually. Very convenient when you're going to make up your own cell connector, CAN bus, or other plug!

Rick and OGM as a whole have been nothing short of wonderful. Not only do they always have what I need when I need it, their support is unlike any other. Rick has worked with me to return (unused) items well past when he should have. The team creates helpful user’s guides and truly understands and are willing to help with any issues with equipment, even when the issues are created by the user (yes, me). This is the place to find and purchase all of your energy needs. Thanks, Rick!

I really appreciate the advice on getting the right aux alternator regulator kit -- and at a great price. Rick and team were super helpful and quick to respond to my questions. This stuff is hard to figure out and they made it easy.

These guys are the best! Very helpful and responsive. The REC BMS has been preforming flawlessly for the past 2 years.

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.
