REC 2Q MNL connector kit is cost-effective

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!

Great feedback for other users, thanks so mch!

Wakespeed configuration tool

The tool works well. It reliably establishes coms with the regulator and provides access to the state of the unit. Programming is straightforward and the Help function, which is critical, is complete.

Thanks for your appreciation of the effort we put into this tool. It means a lot :)

In stock and fast shipping

OGM Energy is my go to supplier for REC, and Wakespeed. They always have what I need in stock, prices are good and shipping is fast and consistent.

Thanks so much!!

Nice work - thanks again

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

Thanks Adam,
Good luck with your latest project ! :)

motorhome install

the wakespeed alt voltage regulator is a special component and priced right at ogm probably cheaper than other sources as i got the kit with shunt. correct me if i am wrong but i think ogm wrote their own software program for laptop use that codes the regulator as well as datalogs and has a much nicer interface than what i see wakespeed advertising. this software is an add on item that was part of my kit by promotion. my application is basically a land yacht (rv) and the goal is to have a diversified electrical generation system and as best i can tell now, the wakespeed is a key puzzle piece and integrates so well with my highoutput alternator. i wish i had a watercooled alternator as i read someone that did was able to basically achieve max output almost all the time, but having an aircooled unit the wakespeed will protect it. based of initial testing, i deem it feasible to to run 1 rooftop ac, basic chassis loads, and probably a tv with out running the generator by having a high output alternator with wakespeed with a good sized battery bank, rooftop solar, and integrated automatic generator start as a backup. that is under ideal conditions, and running the alternator at high loads produces a lot of heat so more testing will be done as well as working on piping fresh air to the alt. honorable mention to Rick for quality customer service, will work on my bms next.

Thanks for the great review and sharing your project with us! And yes, we developed the Windows 10/11 WS500 config tools. Glad it helped!

Continued fast service!

As I build out my system, I have needed to order more parts and bits. I like that OGM continues to have what I need in stock and they continue to ship quickly. Good on ya!

Consistently fast service from the great folks at OGM

It is a please doing business with OGM Energy. Fast shipping, good prices, great tech support.

Great Kit and Service

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.

Thanks for the great feedback! Glad your upgrade went well :)

Fast shipping, WiFi module works as expected.

OGM Energy has become one of my favorite suppliers. Fast and easy to work with. Thanks to Rick and his team!

Thanks for the review and being a great customer!

WS500 Configuration Tool-Config Version Life Time- Windows

Above and beyond.

I had recently swapped out computers and lost my software key and software to monitor my WS500 in the swap. All that transferred was the Home Screen Icon. The team without hesitation looked me up and sent me a new key (or maybe my original one). I am now back up and running.

Thanks Gary! Glad your PC is back up and running :)

Great service

I faced a few issues but Rick was very helpful and available at all time.

I will definitely recommend this company.

Glad we got you sorted. Thanks for the great review!

worth the wait!

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!

That's great news Brian. So glad you are happy with the new 2Q BMS. I think REC really hit a home run with this one!!

Fantastic service and an amazing high Quality product.

The setup and installation instructions are of the highest level.
Customer service was amazing; Rick was quick to help out when i inadvertently ordered the wrong harness and gave me a 100% refund.
I would recommend OGM anytime, a great company to do business with

Thanks Adrian. Glad you are up and running. :)

Easy to use

Very easy to use and much easier to program the WS500 than using the native interface via putty. I like the dashboard display which quickly lets you see the impact of your changes.
Looking forward to the CANBus interface as it is annoying to have to take off the front cover of the WS500 to access the USB socket (not a problem with the software more a problem with the physical design of the WS500 - no idea why they don't have a USB socket on the outside of the box!)

Rick the saviour!

I don’t generally leave ratings feedback but Rick at OGM was deserving of special mention. He spent a good deal of time assisting with the design, and procurement of the charging solution for my boat. If it wasn’t for Rick, I’d still be in a mess. Thanks so much, you were an amazing support. I can certainly recommend OGM for their customer service.

Wow, thanks so much for the awesome review. Best of luck getting your boat out of the marina and back on the high seas!

Controls Everything!

We have been using the REC BMS in conjunction with a Victron Multiplus and Wakespeed Regulator (alternator control) for a couple years now. The REC BMS communicates via CANbus with all of our charge and major discharge sources to ensure that the LiFePO4 house bank on our boat is properly managed. The system has been basically flawless. The only negative is the REC BMS is programmed to keep the house bank more or less at full charge even when we are away from the boat, I would prefer a storage mode that kept the bank at a lower state of charge but have not figured out how to do this with the REC.

This is great feedback. With the new Wi-Fi module REC should be able to add this functionality and hopefully, after the release of the new 2Q BMS they will consider this feature request.

We 500

I phone app doesn’t work no info how to set up expensive waste of money ….

The WS500 app created by Wakespeed is done using a multi-platform language called Flutter. When compiled for Apple IOS, the communications portion of the app gets disabled because Apple does not allow third parties to use the Lightning port for USB serial functionality. There is nothing Wakespeed can do to overcome this but to help we have fully refunded the cost of our Windows 10-11 tech tool and hopefully that helps get you set up and going.
