Hi guys
This is my first attemp to do a DIY 18650 pack "this big" and I will use it on my nephew Battery ATV
So, here is a pic of the old 4 wheeler ( I know... I have to clean it first )
[img=400x700]
Already has a couple years and the original 12v 7.2A battery it's dead so I decied to make a new one using the 18650 that I got from some old laptop batteries.
My 18650 collection ( I know it's small but it's enough for my DIY projects )

I used the "Pack Builder" from this website to organize my packs, and decide to make it 3S6P and I will test it to see the range and autonomy, and if it's not enought I will change it to 3S7P but I have to test it later.

Time to build and solder it!

To make the connections between the pack I used nickel strip from aliexpress and it seems to work just fine.
Just put some flux on each cell, Iron with 350C and apply some solder tin.
It's easier if you use a tweezer to apply some preassure on the nickel strip so it won't come off from the solder point

And it's done for some tests

Time to charge it
I charge for this first time with only 2A just for safety :angel:

The pack IR, it's fine or what do you think? :huh:

Today I will test it to see how it handles the discharge from the ATV, and I really hope it holds charge for some time lol
I will post some pics of the pack inside the ATV and will share the results later
