li-ion won't charge anymore

Post by Seppel18 »

Hi

The 0,22Ohm Resistor on my battery board was blown. So I replaced it, now, when i try to charge over USB or DC-Jack, nothing happens.
When I remove the battery, the circuit tries to charge (4,2V on the Pads), with battery - nothing.

Help :oops:

I can't find schematics of the battery boards, that would be helpful too....

were you using one w/ protection circuits? i've definitely made one of those unhappy. the cells worked w/o the circuit, but probably not recommended (for me since i like some preotection from myself when i'm experimenting late at night).
