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.

it was just the power connect to a USB port and trasmition and another
connection.

Is it possible to combine both signal and power lines within one usb cable?
Would love to see schematics.

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.

Great !!!! Ok you will have a connection diagram? or a file for the PCB?
I meant that I do not want
to mix power and serial connection

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.
