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 ).
Part two takes us through all the technical details and theory, from lithium-ion chemistry to battery management systems and spot-welding nickel busbars, while part one shows us the construction of his battery pack. There are also a couple of videos, which we’ve placed below the break.
Charging the Battery Pack : You can charge the battery pack by a 12.6V DC adapter like this. You can get it easily from aliexpress or eBay. Hope you enjoyed reading about my project as much as I have enjoyed building it. If you’re thinking about making your own I would encourage you to do so, you will learn a lot.
In this project I will show you how to combine common 18650 Li-Ion batteries in order to create a battery pack that features a higher voltage, a bigger capacity and most importantly useful safety measures. These can prevent an overcharge, overdischarge and even a short circuit of the batteries. Let's get started! Step 1: Watch the Video!
After ensuring all your connections are secure and insulated: Cover the Battery Pack: Place the assembled battery pack inside the appropriate shrink wrap tubing. Heat Application: Use a heat gun or lighter to shrink the tubing around the battery pack. This will help secure the cells together and provide a protective outer layer.
Connecting the BMS: B- Terminal: Connect to the main negative (-) terminal of the battery pack. B+ Terminal: Often already connected internally; check your BMS specifications. B1 (or B0): Connect to the most negative point (first cell's negative terminal). B2, B3, ...: Connect sequentially to the positive terminals of each cell in series.
