Let’s get started! Making a DIY battery has some advantages. One of those advantages is the cost. You will get a cheaper price and you are in control of the components. These are the costs involved in building the battery: The total cost of the battery is $641, which equals $0.19/wh.
Making a DIY 12v Lithium-ion battery at home If it looks like a lead-acid battery then it must be a lead-acid battery, right ? Not necessarily Here is how my son made a 12v Lithium-ion battery but first a little background information.
How to make a 12v battery pack at home is an easy project based on multiple Li-ion batteries in series to create a 12v pack. 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 total cost of the battery is $641, which equals $0.19/wh. A good quality battery that I recommend in my lithium battery buying guide costs $0.29/wh.
Gather your materials. For this battery, you will need one unopened can of soda (any type will do), one plastic cup (6 to 8 ounces), and one 3/4-inch-wide strip of copper that's slightly longer than the height of the cup. In addition, you'll need a pair of scissors, a voltage meter, and two electrical lead wires with alligator clips at both ends.
Coincidentally, that DIY 12v 25 Ah Lithium battery also has the exact same BMS as the one my son used to make the 12v 17.05 Ah Lithium battery above. I did not mention all of this above in this thread for fear of sounding repetitive.
