any one have one of these or have a diagram on the charging circuit ?
i bought them and to be honest paid a 10er for the 2 in the hope that they just needed a charger but before i spent the money wanted to see it at least fair workingIt's Sealey, designed to frustrate and fail. Bin it, no more frustration, happy days.
Do you want a 12v led light, or a 3 foot folding led underbonnet light, or a jack that is pure pants, or various other tools I bought thinking they were actually going to work?
Then don't buy anything by Sealey, ever again....
1 yes the power supply i made to suite is 5,1 volt poss even 2amp 2000ma i plug it in to the charge port and on the board (number 1 on pic ) where it plugs in it shows the same 5.1v its only at where the battery connects at number 2 it shows 3.4 volts so im assuming the charge circuit is only outputing the 3,4 where this is susposed to rize as the battery is charged i dont knowAre you saying that off-load your home-made charger shows 5.1v, but when connected to the charge port on the torch it drops to 3.4v at the port?
What is the current rating of the charger, is it 1 Amp?
What current draw do you see when connected to the torch?
Does the voltage at the charge port rise from 3.4v as the battery charges?
Have you tried briefly linking your charger direct to the wires on the battery, without using the charging logic on the PCB?
the light has a torch on the end and a 2 light dimming front facing torch so assume its part of that thenThe 16-pin CD4017BM is a Decade Counter/Divider, i.e. a chip that can count to 10. I do not know what it is doing in this torch, but I don't think it has anything to do with charging the battery
this seams to have only 8 legs ? so easy to remove how much are they or do we think it blown for a reason ?The defective TP4056 chip would need to be replaced with a new one. No programming is required, but that chip may not be the only fault in the charging logic on the PCB.
i think this way unless im very lucky in finding a case that i can sink in to the the case with a cover for the battery and this will lightly take out one of the mangnets so makes the unit a bit less useable so id rather not go this was if possableFor single 18650 Li-Ion cells I use a Nitecore i4 charger. It has 4 charge slots, automatic recognition of battery chemistry, and can handle NiCad, NiMH, Li-Ion. I use it to charge cells that I have removed from recycled Laptop batteries, and use the cells in LED torches and head-torches
this is they way that looks good to me if the cuircit cant be repaired at least it will all be contained inside the unit and charge safely and keep all of its featuresWith the TP4056 chip being blown-up, the torch no longer has a charge control circuit. You could remove the battery to charge it in a safe regulated external charger, as suggested above. Alternatively, if you have some equipment that has a USB output point, you could buy and fit the single-cell USB charge control board I linked to above, inside the torch. The board has a USB socket, you would have to cut a rectangular hole in the torch case and glue the board in place, then piggy-back the board output directly to the red and black battery wires ( i.e. connector number 2 ).
