Cordless Electric Drill Repair | Replaced 5S 21V 20A 18650 BMS Charging Protection Board Part-1

In this video (Part-1) I’m going to show you how I have fixed the cordless electric drill issue. Issue= isn’t run for long and short-circuit noise from the BMS. The problem is with the Push Button Trigger Switch DC 7.2-24V, which causes later on the issue with the 5S 21V BMS charger board of this drill battery pack. Throughout this video, I have done several troubleshootings to identify the exact causes of failure.
