Thank you for all your videos Yousun. And thank you for this drill battery rebuild. My question is, can I use Ni-MH charger to charge this new Lithium-Ion battery with the BMS installed? this is my big question. Please advise. Thank you again.

[@yousun2827]

Tell me about the battery and charger model?

[@yousun2827]

The original battery on the video has no protection board, and the voltage is compatible. You can use the original charger directly.

[@alphameric3786]

@@yousun2827, Actually, I have original NiCad Hitachi DS18DVF3M, and want to convert to Li-Ion battery and unsure if I can use the original Ni-Cad charger. Thank you very much.

[@yousun2827]

Yes! You have to take the battery apart and see that there are several NiCad inside.
