Hello My Motorola batteries are all swollen and therefore defective. anyone has a solution for connecting to power directly to the battery connector by usb? I thought used a 3.7V zener diodes in parallel between the - and + USB power and a series resistor. Thank you.

I've used LP3874. You'll need a fair bit of capacitance in order to transmit. //Peter

Nice !!!! How you connect? it was just the power connect to a USB port and trasmition and another connection.

I designed a PCB with a battery contact and a case to hold it in place. I've seen several people solder connections permanently to the phone.

I don't understand this. //Peter

Great !!!! Ok you will have a connection diagram? or a file for the PCB?

A 'Fucking' Battery, I haven't ever seen one of those before. Perhaps some decorum in your choice of words on a mailing list would help.

Is it possible to combine both signal and power lines within one usb cable? Would love to see schematics. -- best regards, Max, http://fairwaves.ru
