You must remember some of our members English is not there first language and alex is one of those people he is in Serbia maybe that's why he couldn't go in to too much detail, this is not a dig at you just a explanation , it's not unlike your QTH reference in your profile it's a map reference and some of us dont understand map references so we dont your QTH .

Aleksander, you are a star my friend.
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) 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. 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. 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 )
Well done.

No flea intended Bozzer mate, I was just explaining about Alex is not a 26div member and his English was his second language ,I think alot of people sometimes make the mistake and forget we have members all over the world and some cant even speak or write English, you wait till you see a posting in a foreign language lol .
