MakerFocus10pcs TP4056 Charging Module with Battery Protection 186 50 BMS 5V Micro USB 1A 186 50 Lithium Battery Charging Board

Awesome product @ a great price! I'm using these to make rechargeable battery packs with salvaged Li-Ion cells. Very easy to set-up and use and the size makes it easy to fit inside small project boxes. I like these so much I actually made 2 videos highlighting this part AND I plan to order more soon for some experimenting (new project ideas). Thanks for a great product, price and prompt delivery, Dialed In DIY.

Great solution to charging the 18650 cells!!

I bought a six pack of these, tested all of them and they worked perfectly, the quality of manufacturing exceeded my expectations. Would recommend this product to anyone.

Work well, but they get extremely hot under load.Wish they offered a 0.5amp version as well.

When the blue LED came on with power, I felt like the Mogwai in "Gremlins"- "Bright lights, bright lights!" - dang, that thing is bright. Just waiting on a soldering iron to affix the crocodile clamps I bought separately and we'll get to charging!

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.

Excellent little boards I am very pleased. These little guys are great for controlling the charge and discharge of a single 18650 cell. They get a little warm while charging so design your circuit properly.

Works as intended. I have several 3.7 volt batteries that are going to be converted to power bank chargers. Exactly what I wanted.
