![]() ![]() Reassembled, and still a number of the batteries failed to work. I disassembled the pack, recharged/tested/recharged the cells (all still had great capacity). I presume the internal battery circuits will take care of cell balancing, but I suggest checking the individual cell voltages periodically. Might want to put a ~4.7 K resistor in series for protection. I suggest applying between 1 and 2 volts. When the voltage was 0.5v or higher, the main +/- "opened" and it was possible to charge the battery. It was linear from 0.5 to 2.0 volts suggesting a pure resistance. The battery continued to charge when T2 was disconnected, but the light on the charger was red. Voltages with a half-charged battery inserted: I couldn't read the numbers well, my best guess is 10266A J1A4B Two 3-lead semiconductors, I presume they are MOSFETs. Lots of pictures and information on the web so I won't repeat. Maximum current of AH / 4 is safe, more might be possible if you know the battery specificationsĬharge in a fireproof container and don't charge unattended. Maximum of 21 volts (better is 20.5) for a 5-cell battery Use at your own risk: I suggest the following: Warning: Using the following could bypass the thermal and electrical protection circuits. I did a teardown on the battery and a (borrowed) charger and found out how to bypass the Battery Management System (BMS). ![]() It does not store any personal data.I bought a Biswaye P103 (Chinese) battery to power my Ryobi drill, but when I tried to charge it using my bench power supply, it wouldn't work.
