TP5000 module review (and technical details)

Keeps one from discharging into another, and hopefully, they'll be in about the same condition. Especially if they came out of the same battery. I imagine you could do the same with the TP5100.

Those tiny resistors are a challenge to get off. I've managed with a fine tip iron and tweesers. Not every attempt has been a success though. I've had to through out a few failures.

I hope things go well, whatever you do. Smile
Thanks Mike. This is a good suggestion, and I'll implement it. The road to a powerwall has been tough for me so far, but i'll get there

This goes for the TP4056, but can probably be applied to the TP5100, too: When I charge cells that I find in the 1.0V to 2.0V range, I wait until I get 4 within 0.05V of each other and put them in one of those 4 cell Blossom holders that is attached to the TP4056. I then get an old USB charger that was used for something like a bluetooth headset that has a limited output to 5V and 100mA and use that to charge the cells super slowly (around 25mA per cell), all the way through the charge cycle (takes forever). I have another USB charger that was limited to 5V and 600mA that I use with cells that I find between 2.0V and 2.5V (again in groups of 4). That's another way to limit the charge without having to change resistors on the boards.
