18650 - Part 4 - Battery cells bulk charging and discharging with TP4056

Finding batteries is one thing, but you also have to test them. Charging and discharging will be a very time consuming part of your build. To make it easier, you can build a bulk charger and discharger. Here I explain the most used items for a DIY yourself bulk charger and discharger bank. In the next episode I will explain more about the OPUS BT-c3100 charger-discharger. So before starting ordering, watch part 5 of my series and then decide which way to go.... or go both ways, like I did.
