Maybe the individual cell (voltage) balance leads were not hooked up properly - interesting that you only have 1/2 of 36v.18650 said:I installed a 36v BMS, all seemed fine, when I tested the voltage I noticed
B- Battery is at 36.6v
P- Load is at 18v (approx)
C- Charger is at 18v (approx)
The device drawing the load would not work at 18v
Has anyone come across this ?

Make sure its connected correctly with all cells in balance otherwise the board may have went into protection mode.
