Lipo charge/boost/protect board in 18650 cell holder format

Peter6960 published a new build: So couple months ago, GreatScott made a video where he designed a circuit. Nothing too innovative, just the same TP4056 charger the MT3608 Boost combined on one PCB. He did add a Lipo protection circuit though, initially using the same DW01. But then, the Aha moment from this video, he […]

LiPo batteries hacking and refurbishing

Karman wrote an article showing how to refurbish dead batteries to extend its life: One of the difficult parts when prototyping is to find reliable power sources. Today is still hard to find the battery size we want to use because country exporting frontiers stops these chemical packages. Here I’ll show how to refurbish dead batteries […]
