Review on ⚡️ MakerFocus 4pcs 18650 Charging Board: Dual USB 5V 2.4A Mobile Power Bank Module with Overcharge/Overdischarge Protection - DIY USB Power Bank Board by Matt Venable

Revainrating 5 out of 5

Great board for 1s Lipo batteries.

With this product I was able to revive a 1s lipo battery that had a bad circuit board. Works with 18650 and other Type 1s (3.7V) sources! The display's backlight is very bright. And directly in front of it, the viewing angle is limited. But overall it works great!

Pros
  • Easy to use
Cons
  • Discontinued model
