Aleksander, you are a star my friend. Smile


I wouldn't worry, we have many members here where English is not their first language.

I liked your posting simply for seeing someone else making their own stuff which is something I enjoy.
It's good to show the fruits of your labour.


All my best to you,
Victor

i buying old laptop batteries for a long time. take them out of the original packaging, check and sort them.make powerbanks, led lights for night fishing, power supplies for many things.used 60 pieces of 18650 batteries link in 3 groups 20 pieces each (1group=4,2VX3=12,6V)
ready to dx field  13722310
each group has 20 batteries and are connected in parallel to get as much capacity as possible(Ah).each group is connected (+,-,+) 4,2+4,2+4,2=12.6volt.
ready to dx field  13703910
I used a fuse wire to connect each battery separately to the terminal.should be very careful because this type of battery is very dangerous.unprofessional making,handling,charging can cause a fire.
ready to dx field  13698010
when making such batteries battery management system (BMS) MUST BE USED

Fantastic stuff Aleksander!

Really good of you to share the extra information.
(I've stripped apart an old laptop battery or two myself just to get the cells Wink)

Well done. 👏
