so i removed the circuit from battery and it looks like a ling thin circuit, i connected the circuit to the board again without battery and connected the power cable to + and and -
but again nothing works, i checked with the multimeter that circuit is getting 3.7 volt but from there to motherboard, no power.
why
circuit is working fine, then i connected the power cable directly to the motherboard without the circuit, it is getting 3.7 and i increased it to 4.3 volt but still no power
i will try with new usb cable, again
ok, so removed the circuit from the battery and it look like this one
i tried several other ways, like connecting the charger output directly to the motherboard, positive and negative, but no sucess
then i tried a 10k resistor and 10k thermistor and connected negative and white , ..
see
here i connected 10k resistor
i tried with 10k thermistor
then i connected the circuit back to its original connection but wihout the battery and sent power from charge to positive and negative on circuit
i tried the buck converter also,
but its maximum output i could increase to 4.3 volt only becuae it was connected to 5V charger
what else i can try
i think i will change the power cable
using a buck converter with 5V charger is limiting the output to 4.39V max
i am thinking to connect 5V directly from the charger with a new thick cable ?
any suggestion
