    Neither of those should stop the mod turning on. The 510 looks OK actually, just a bit messy the way the insulation was cut off the wire.

    Not turning on at all, if it is a simple problem would be no power to the board. You really need a multimeter so you can trace the wires from the battery to the board. If the board is getting power and it's still not turning on, then the fault is on the board somewhere. Check if there is a fuse soldered onto the board etc.

    ETA: You said you were trying to remove the wire from the "chip" and I was freaking out. Actually soldering on the legs of one of the chips should not be done without some planning and precautions. I think you actually mean the PCB (printed circuit board) though. Soldering on the board should be OK, but if you overheat any of the semicondutors (chips, transistors, power regulators etc) it can kill them quite dead.

    ETA again: 40 watts should be plenty for simple jobs. If it's not a temperature controlled iron though, be aware that the temperature will continue to climb the longer it is plugged in and not used.

    Yeah I meant to say removing the damaged wire from the PCB, but the solder on the pcb would not melt.

    This mod was working for a week and then didn't want to power up. No idea what is wrong with it apart from those two wires.

    What would the humming/buzzing noise be? (When the batteries are inserted)

    Lead-free solder takes a lot more heat to get it to move and can be finicky to work.

    Seriously, a buzzing noise can be typical of an inverter chopper circuit. (most boost circuits are some kind of inverter) If that were the case if it's making that noise when the button is not pressed, it sounds like the board is faulty.

    Just guessing here - see what the others say.

    Nope not faulty. I shoved it all back in there and for some reason it began to work, for now...
    It must have been a kink in the wiring. I left the split wire with tape in there. I don't want to disturb it whilst it's working.
    I'll fix it if it stops working again.

    Post it to AllyP.

    She can introduce it to George, the clock.

    Return post, all fixed.

    I think the internal space is too tight.
    Is it much work taking the dual 18650 battery sled out and connecting a lipo battery in there??

    You'd need to be quite sure the mode is able to charge a 2S lipo correctly.
