I bought an second hand Electric Motion 5.7 from really cheap with an broken "battery module".
The previous owner opened the battery and somehow managed to damage the BMS.
Then he contacted electric motion and got an offer for an new battery for 4000 pound.. The BMS can not be sold desperately.
So, then he sold the whole bike to me for 1000 pounds.
I removed the defective BMS and charged the battery by bypassing the BMS and monitoring each cell with an regular volt meter.
Some cells were a little bit off but not more than 0,1V
I did some manual balancing by charging some of the lower cells and discharging some of the higher cells.
Now they are all within 0,03V.
The rest of the bike works perfect. It comes originally with an Kelly Controller KEB 48601.
I own two other bikes with Kelly controllers so i already have some knowledge to that brand, and cable/software.
The motor is 5KW made by Golden Motor and it has an reduction gear box as this is an trail bike.
Battery is 13S, 25 AH.
Now I need an new BMS and it needs to be built in to the battery. I would like to have Bluetooth.
Any recommendations? I am looking at the Speedict Neptune 15.
But i can not let all the power go thru the BMS as this needs 200A power, acutally the fuse to the controller is 300A.
Can the Speedict instead control the large relay allready build in to the battery module?
