RS485/UART SW for WINDOWS TOOL:
This is the first JBD BMS that I have installed. I was very impressed with the quality and assembly of the unit. It would be very helpful to have a detailed wiring schematic included with the unit. We are building a 12s 36 volt 304 ah battery and cannot find a wiring schematic for that voltage. We have it paired and all inputs entered however it says it has 14 cells and we can not change it to get a cell voltage read out. Still working on it.
All right, like again…
Good material, works perfectly.
Will this unit work with the JBD-LCD02-RS485? I keep getting a ‘Connection Error’ message on the screen. This connects using the RS485 connector on the left side of the circuit board.
