Reconfigured my battery packs and added a Daly 72v 60 amp Bluetooth BMS to each pack.
They install pretty easily and configuring on your phone is pretty straightforward and simple. Few little things i still need to figure out but overall they do seem like pretty solid BMS. Few things I wish they could modify in the software, the biggest would be the ability to monitor more than one pack on Bluetooth at a time. The other thing that is pretty lame is the long lag time from the BMS to the screen. It's about 5 seconds lag from being accurate. So when I dump some high power or go WOT the display takes a while before displaying the current. It just makes for a pretty useless current monitor,one of the features I was looking forward to having available. I could have gotten a dumb BMS but having the ability to check on the different cell voltages in each series string is pretty cool. Seeing a confirmation that my battery is well balanced is something you don't get with a BMS that doesn't utilize Bluetooth.
When looking for a good BMS you will soon figure out that there are few well documented models available other than Daly and maybe ANT. I hope we see a US company startup that offers Diy BMS options.
