Hi everyone,

like many of you, I am building a charging rig to be able to process quickly my batteries.
I went for the TEC4056, which are based on TP4056.

Now my problem/question: I want to solder the charging cable (not gonna use the usb port) but I don't find the in+ in- like on the TP4056 board. Could someone help me on that one ?

I am not sure but I think this will work....could someone confirm ?

Thanks a lot.
I will create a thread on my build when I'll have some progress made.
 
Looks like it might be here instead?
Bit hard to see exactly where the tracks connect, negative is OK, but positive should be same as 5th pin in USB not the other side of the 330 resistor

I have a battery tester that uses a micro USB cable for its power. I wanted to solder wires to it for power instead so I poked it with a multi meter a few times to find the positive and negative inputs. On my device the negative is the port itself and the positive is a small spot on the bottom side under the port. After soldering the wires it works perfectly fine.
