Just read the REC manual. Its passive balance, needs relays and shunts, and only handles 100amps. Its great that it works with Sunny Island though.Thanks, I will take a look at the REC. If it looks like I am staying with SMA, then I may have 3 brand new and 1 lightly used 200amp, 2 amp active balance, with temp sensors, Bluetooth enabled BMS's for sale.... I agree with the need for active balance. My bank cells are usually .008V apart max.
I may just try to get the CAN or RS485 working on the Heltec though, as its much cheaper, does 200amps, has Bluetooth, works with a Raspberry Pi and free software, and has active 2amp balancing. Plus I already own 4 of them... ?
