Hand tools and fabrication machines
In this electronic DIY project, you will see how to make a very convenient 18650 battery charger using the popular TP4056.
This home-made charger can charge 6 lithium ion 18650 cells at the same time, making it easy to use.
I am also using a voltage tester applied to every cell individually, and current tester to measure direct current applied to all the cells.
