              that charger requires a holder . or add a socket to my one but i suppose a holder is cheaper

                    no.
                    the reason for the "unnecessary info" is because i was thinking of alternative solutions.
                    i cant find your lamp model,
                    i assume it has a micro barrel connector on it going directly to the battery terminals though.

                        6800mAh my ass, i'd love to throw that in my Li500 analyser

                        get a decent charger - they arent too expensive.

                          been looking for a decent charger and they cost a lot . thinking of getting a tp4056 module for now ..
                          i will let one of the people i work for buy me a nice one along with a bench power supply and battery spot welder . plus anything else needed for rebuilding battery packs properly .

                            what voltage is in the "charger" ?
                            if it's 5v then you could put a tp4056 inside it

                              i thought of buying a holder and module then using a usb charger i already have . costs less than £4 to get my torch batteries charging for now . then go for something big and fancy with digital readouts later on for sorting cells for rebuilding/repairing 80v packs .
                              i am sure i have plenty of components here to build a 4.2v charger circuit with led lights included but cant really be bothered . modules can be had for about £1.50 . it would possibly cost more using parts from my stock .

                                i can probably send you a module - i think i have some spare.
                                you have the holder already i presume?

                                      quick follow up ..5 chips arrived from china . first one charging at 4.3v . not happy so randomly picked another one 4.12v . i think that's near enough .
