https://www.youtube.com/watch?v=xddY02m6lMk If you need a 12v battery and want to learn how to make it from 18650 cell watch the video it has details on how to make a new battery at home.You can make this battery from 18650 cell that can be harvested from laptop batteries or power banks, a thing that has Li-ion in it can be reused and reconfigured in a homemade battery

You have two options one is to solder the batteries and then make your connection series or parallel or mixed

i have found that this 18650 battery holder works just fine and you can reuse them for other projects.

The important steps when making a 12v battery:
Charging the cells

Discharging and see the mAh of each battery

Match them to closed capacity

Make your battery pack by series or parallel connection

Parts needed for this project:

18650 cells

18650 battery holder

wires

In the picture, you can see a very easy diagram on how to solder the wire

keep in mind that the positive + and negative - terminals have to have the same length

to keep the pack balanced that's a tip for future arrangements of combined series and parallel connection

Is very easy we will alternate the cells when we gonna put them in the first cell up the plus + terminal

second, up part is gonna be the minus - terminal and the 3rd cell with the plus terminal upwards.
