10s 4p lithium Ion battery

So I saw The Beast trying to find out how to build a battery pack and decided to give it a try to see if it was really as he made it seem (it was not). Now after doing the research i got interested and decided it was about time to switch from Lipo. Now I going to build one and made this plan its pretty crappy but I want to see if there is any issues with it. I am trying to make it as flat as possibly and was wondering if I could solder the batteries in series and only spot weld them in parallel.

I have an idea in mind for what I want to get for these but want to see what you recommend for a BMS, a cell, Charger, and a spot welder.

The samsung is what i saw to get and is what i am planing to get. Thanks.

Pretty sure the group buy ended

Ah snap true. But he sold 50 in no time so I guess in a week, there might be already enough interest in another one. Especially since you only need a min of 2 for an order. One thing that I understand but still bugs me is that a few esk8 deciples are allowed to create group buys :upside_down:

What kind of spot welder and nickel strips will you be using?

Yeah i hope it goes back up and it would be nice to be able to start group buys.

apparently any pure nickel from ebay will do fine. 0.15mm is the minimum thickness that allows for proper amp draw - this is what i have read. Dont have own experience yet.

Ok i look for 0.20 mm then that seems good and any idea about the spot welder Thanks

This paired with a cheap car battery is supposed to be one of the better options. Not really cheap in total though.
