Sometimes you want to make something no matter what, and sometimes you lack some tools and when you find out that no one will sell them in a 50km radius from home, you just say, fuck it, I’ll do it anyways.
I started by striping out the heat shrink from the 6S 4500mah 25C Turnigy battery until it looked like this:
Then you have to unglue the cells, I just wanted to cut it in half making 2 3S stacks, so I only needed to separate the middle.
You have to help yourself using some credit card (or in my case, my Chilean public transport card):
Do it carefully but don’t be afraid, if you’re not insane you won’t break them. Once they’re separated:
Now you’ll have to cut the (I guess aluminum) tab that joins the two middle cells so you can put the two stacks side by side, I cut it with a pair of scissors.
Now we have to re-join those cells with some piece of cable, 10AWG will do. So when I read the original How I made my lipo packs slimmer I knew I needed the aluminum solder paste to do this. But I couldn’t get it so I tried soldering without it and obviously couldn’t tin it.
Here’s the barbarian part of my unprofessional tutorial , I figured that if I cut a hole in each tab, I could coil some copper wire through it and solder it against itself.
Here I’m punching a hole with my mom’s knitting needle lol.
Before and after soldering:
And proof that it works:
I know I have to secure that part because movement can be dangerous, but then it totally works!
Let me know what you guys think, I wanna thank @barajabali for making the original thread and helping me accomplish this. I hope not to bother anyone by making a new thread about the same topic, see you soon!
