EBL charger to recover batteries
#11
^^ That's the way i'd do it if I could SMD solder the TP4056, but I can barely regular solder, so I just used chargers that are rated for 0.1Amps like for an old bluetooth headset. They will deliver 5V at 0.1 Amps and achieve the same result with no soldering.

it is not necessary to use a smd resistor.
i use a 10k and 3.3k in series tacked to the pads after removal of the stock r.
i even have 1 with a 10 turn trimpot so i can set whatever i want.
sounds like Generic needs to curb shop on trash day for some practice fodder.
plenty of biodegradable chinese electronics on the curb.

I didn't mean an SMD resistor, I just meant the pads on most SMD parts are so close together, that I usually end up creating an unwanted solder bridge. I love the idea of using a potentiometer and being able to change the resistance value infinitely. I was just letting people know that there was another way to lower the output of the TP4056 without soldering. Plus I love re-purposing old things like wall-wart chargers.
