MakerFocus 10pcs TP4056 Charging Module with Battery Protection 18650 BMS 5V Micro USB 1A 18650 Lithium Battery Charging Board

I really like these guys. Small, charge batteries well. Power for projects seems to be spot on. Just a convenient little device to have around. Price is sure easy to handle as well.

Works great

It works however you NEED a USB a to type c charger. Type c to type c WILL NOT WORK as these are originally supposed to be using micro USB.

Purchased these to build a 'charging station' to help charge 300-ish 18650 batteries, and to convert my Xbox 360 controllers to Li-Ion. They work pretty well, but i have noticed the "full charge" voltage has dropped after 30-ish cycles on the ones i used in my charging station from a steady 4.18v to 4.02-4.06v. Personally not a big deal, but something to cinsider. Overcharge protection works perfectly fine on all of them thus far as well. Charge current also isn't 1A on any of them, ranging from 650-800mA, but again - personally not a big deal. Overall very pleased with the purchase, and may be purchasing more here in the near future

Great solution to charging the 18650 cells!!

Muy buen producto

I had one board burn up on the first try. I ended up buying some thermal pads and repurposing a heat sink I had laying around. Now I can charge my flashlight batteries at work. Using a heat sink keeps the temperature down which I'm positive will extend the life of these little circuits. For my second project, I changed the resistor (R3) to lower the charging amps. I added just the thermal pad to this one and it doesn't warm up that much.

These boards appear to be well made. They're easy to read and soldering to them is a breeze. They've made my new project much easy to make. Solid purchase.
