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.

Nice video. The Part I really wanted to see was the bit you missed out. Taking out the contacts from the board and dc port and how you used them in the battery connector. I bought the bms to give good contacts for battery adapters I need

After done soldering, you must charge to active the bms. Learn from sorin

Such a great idea. Are those purple cells not of good quality? I saw a guy using them in a ebike battery pack.

@KetansaCreatesArt Жыл бұрын

@Pinki Chowdhury , They are called adhesive insulation rings. If you write specific number of the lithium cell you will get the exact one. for example - "18650 adhesive insulation ring".

May be MOSFET is shorted, Check MOSFET first in inbuilt bms

@LahisTechLT 3 жыл бұрын

I’ve thought it, but this inbuilt BMS is a waste. I wonder how still it’s work with just one high power low internal MOS at least it should have 2or more to balance; poorly built. No Temperature NTC either, hence decided to move on to a replacement. Thanks

All good if you are doing this as a for profit business. For the average person the cost of special spot welder, battery testers, misc tools and parts is too much. You could replace your old battery packs for new ones several times over and simply plug them in to the tool. So thanks but No thanks.
