Finally finished balancing the cells. They are all within .003 volts after resting overnight. Probably overkill, but can't hurt.
Got the cells all wired up. The BMS is working properly. Haven't switched over yet. The Victron battery monitor is not working. Hope it's just the RJ12 plug on the cable that I might have damaged fishing it through the floor. I have a cable tester and crimper somewhere in storage but won't get there for a couple days.
The BMS cell boards each have a red led that blinks a code to tell you if everything's ok or you have or had a high or low voltage event. Well one of the boards led wasn't lighting up. Thought I had a bad board or I let the smoke out of it. Nope, the boards are coated with black plastic and on this one the plastic was covering the led. So after lightly scraping the plastic off it is now blinking.
I know this sounds like quite a bit of work but I'm flying blind here. Not a lot of info out there on these batteries. But if anyone wants to do this on their coach I'll be happy to help. And the second time will be much easier and quicker. I work pretty cheap, burger and brew and I'm happy, happy, happy!
