Hi.
A five cell battery pack salvaged from defunct equipment has three terminals.
One is permanent (+)
The second is mosfets switched to battery (-)
The third is some control/sensor/something, that may allow charging.
How would you guess what to apply to the third terminal C in order to enable charging the pack ? a resistor to (-) ?
Original charger or equipment not available to measure anything. Pack works beautifully well repurposed, want to keep it healthy.
On image, the three terminals are at bottom, the 5 cells are under the board, schematic with not much detail, mosfets by heat sink...
