Thank you very much, great job! Intelligent procedure how you connected the contacts to the BMS. A man studies all his life and dies stupid. Greetings from Switzerland
What's the purpose of the last couple of solder spots you put down on the nickel strips, but that weren't connecting anything? And where did you get those small snips?
There were 2500mah cells in it and i changed them to 2000mah. Because i had only those :/ the red light blinking red means battery damaged :/ is this light because the cells smaller capacity? Thanx for answer
I repair Li-ion batteries from well-known world manufacturers as a hobby and only for personal use. My experience so far is that if we consider that most of the famous brands install cells of uniform high quality, Milwaukee is the best..Why? When you change the broken cells or when you adjust their voltages, the Milwaukee intelligent charger erases the error and activates the battery. With other well-known brands, it doesn't work (my experience so far), but you have to change the PCB of the battery as well. I would be interested if you know which other professional brand has these features? In addition, Milwaukee batteries have a high-quality, rubberized housing. Other well-known global manufacturers are afraid of possible expensive compensation costs (explosion and fire) and have made it impossible to reset the electronics in the battery. All the cells are correct, all the voltages are even, and the battery ends up in the trash? Protection of the natural environment??? Greetings from Switzerland
It was great! I have a 36-18 multi-volt battery! When I connect it to the device! Its batteries are getting hot! And it catches fire from one of the battery connections and is cut off! This happens without turning on the device! As soon as I install the battery on the device! What is the cause? can you guide me Thank you🙏🏼
I guess you are using 18v drill/device. The battery contains two rows with 4v x 5 lithium batteries aka 20v. To make 36v it combine the 2 rows in series. But when you connect it in 18v device it makes both rows work in paralell. A known fault is that one of the rows has cells in it that are broken. Thats why it gets hot. The charger using 18v to charge the cells in paralell.

I thought we was going to see a repair not a renewal of batterys good video thou

Do these ones deactivate the board when power is removed as a way to prevent repacking cells like miluwaukee does?
I changed 2 dead cells in mine . Now have 19v on tester and works in drill 🙂but😭 still flashing when in charger😭 what might fix the new issue?
I ruined one of the case screws. What size screw do I need to get for the Hitachi 18V battery pack casing?
