I have a Sony battery pack called BP-200 and replaced the old internal battery with new Lithium batteries. I also drilled a whole so it can be charged with micro USB cable. I'm wondering can it charge through the discman like D100 D150 or D250? If I insert the power adapter into these discmans with BP-200 attached, can it charge BP-200?
The voltage of BP200 is 7.4V, how can you charge 7.4V battery by using 5V USB? Pls refer to the thread in this forum regarding BP200 modification by LIPO cells.
