I have two (2) new 48V Jiabaida BMS's for sale. I purchased them but my voltage for my panels is at 30 volts so cant use them and went back to a 24v configuration. These have all the wiring and BT module. These are 100A 16s LifePo4 (3.2v cells). Selling for 65$ each (covers shipping). Please let me know if you are interested.
