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!!
