CR2 Advanced Photo Lithium Battery Retail Pack -

all right hello everyone my name is Jake and today it's gonna be part two of the microwave transformer swap while their group batteries project lecture what to call this thing quite yet but in the last video I made this contraption and this is a spot welder for lithium-ion batteries made out of a microwave oven transformer if you want to see how I did this check out yesterday's video but essentially what it's going to do is weld on strips of nickel to connect with EMI on specifically 18 650 battery cells so today I'm gonna do just that today we're making a battery pack it's gonna be similar to a 12 volt power make that you can use to power a number of projects in any sort of capacity you want let's dig right into this and get started so I'll show you how I used this spot welder to connect the nickel strips together and then I'll show you how to solder on this battery management circuit
