I've tried twice now with two usb audio recording thumbdrives to add a larger battery after dissassembly. The little battery in the thumbdrive is a 3.6v and I've tried to solder in a 3.6v cell phone battery for longer record times. The first one got too hot and things melted. The second one will get hot but then I remove the wire before damage can occur. When I put the small battery back in place, the recording feature still works, but each time when I try the larger battery, things get hot right away and I have to remove the wires.
Of course I'm careful to use my meter to make sure that I'm connecting the polarity correctly. If I remove the leads quickly, it does not damage the circuit and I can replace the smaller battery and it's fine. There's a very tiny cb between the battery and the thumbdrive that I'm also careful to include in the circuit.
Thanks ahead of time for any ideas on what I can try...
