Dear all,
I have received my PCB with schematic that was discussed here in the Forum.
I have a repeating issue.
I have a series FET connection method (discharge and charge FET are in series) and a steady 15K resistor between B+ and CHGST.
because of that I cannot power down the PCB by shorting the thermistor.
so when the assembly is done (I try to do it squently but it is a very difficult assembly), I have an "open cell" fault that just do not resets.
what is the right way to do it? what will assure a safe and fast assembly and activation of the pack.
my suggestions:
1) to disconnect the 15K resistor during the assembly and short the thermistor during all through the assembly,
2) disconnect the resistor the will go to BAT pin (R4) during assembly - which means no power to the inner voltage regulator.
needless to say this is extremelyextremely urgent.
thanks for the help, schematic attached.
