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

18650 battery . torch is xml-t6 ultrafire ..
now we have the unnecessary info out of the way does anyone know where i can get a chip in reasonable time .

Re: equivalent for HT3582DM

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.

Re: equivalent for HT3582DM

the battery is separate and looks like this .

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 .

Re: equivalent for HT3582DM

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

Re: equivalent for HT3582DM

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 .

Re: equivalent for HT3582DM

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

[petehall347]

Re: equivalent for HT3582DM

have just ordered a module and holder thanks .

Re: equivalent for HT3582DM

built it up earlier .. rough and ready and working fine . glued to nice lump of aluminium just in case anything gets hot .

[petehall347]

Re: equivalent for HT3582DM

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 .
