REC-Active BMS Balance issue?


  • I\'m new to REC but just got my ACTIVE 12V bms. I had a pack that was fairly balanced before hand, but was configured as 24v. I reconfigured to 12v 4s2p pack just to play around with the BMS and the cerbo. I see it ramping down the charge current when a single cell hits the balance voltage of 3.45, but then I see cells 1 and 2 balance (I\'ll put screen shots for that later as they are at home) as cell 3 was the highest. However cell 4, the lowest, doesn\'t seem to move for over an hour. Is there any way to check the logs to see if any redirect balance current is making it to cell 4? Ignore the drop in current, I turned off the chargers when I went to walk my dog.  


  • It looks like the BMS is pulling back before your BMS starts to balance. You can try to enable balancing at a slightly lower value. We are putting together a bit of an instructional video on how these all interact but it is still a few months away.
