How To Make 12V 15Amp Lithium Battery Without Spot Welding and Soldering
Hello friends, This is a very cool project to make 12v lithium ion battery pack using lithium battery cell without spot welding and soldering. This battery will give you 15Amp capacity but output 300Watt output at a time. This is very simple to make just follow all the step and make your own battery pack.
Place the cells into the holder. I had a nice cell holder that came with the battery box I ordered.
If you don't have a holder you can glue the cells together using hot glue.
Pay attention to the battery configuration at this point (in my case 7s6p).
I should have checked the cells voltages at the previous step but all the cells were at the same voltage.
Now it's time to cut the copper wire according to the configuration of the battery. Make sure you don't miss any cells and don't cause any shorts.
I placed some flux on the cells before soldering.
With the soldering iron set at 425-450 Celsius (800-850 F), I started soldering the cells and the copper wire. The trick here is to use high temperature with a low contact time on the cells in order to cause minimal heat damage.
Once the battery is all soldered and complete, you can check the voltages again (they should all be the same) and use an RC charger to charge/balance charge the battery.
I hope you enjoyed this instructable!
I've built several batteries this way and 1+ year after I saw no sign of degradation yet. These batteries are used in electric bicycles.
