Materials needed: 2x 18650 or 21700 cells (they must both be exactly the same cell!) Let’s first list the tools that I used: Making a battery pack is dangerous. Ensure that you have a basic understanding electricity and lipo & li-ion battery tech. This guide might not be perfect, so proceed at your own risk.
Add wires Cut two stranded wires, about 2″ to 4″ long. Strip the ends about 3/8″. On the end that will connect to the battery pack, spread the strands of the wire. On the end that will connect to your circuit, twist the wires together. If you have access to a soldering iron, tin the wires to keep them together.
To make the battery pack, you have to first finalize the nominal voltage and capacity of the pack. Either it will be in terms of Volt, mAh/ Ah, or Wh. You have to connect the cells in parallel to reach the desired capacity (mAh ) and connect such parallel group in series to achieve the nominal voltage (Volt ).
Battery connector (I didn't have to buy this, but is only a couple of dollars if you need one) Step 1: A Bit of Theory First... In order to make a 2 (or more) cell battery pack from 18650 batteries it is necessary to connect them in series with each other, so that their voltages add up.
We’re about to make some covers to protect the top and bottom of the battery pack. Take some double-sided tape, cut it to length. Then apply kapton tape (or electrical tape?) on one side. Measure some shrink tube. It should stick out about 8-10mm on each end of the cells:
The negative of one battery has to touch the positive of the next battery. Use your battery pack You can use your new battery pack by twisting the wires on the pack to the wires on your circuit project. You can also solder a 9 volt battery top onto your pack wires so you can use the standardized clip of the 9 volt system.
