FAQ
All About 18650 Li-ion Battery Pack
A battery pack is a set of any number of identical batteries or individual battery cells. They may be configured in a series,
parallel or a mixture of both to deliver the desired voltage, capacity, or power density. 18650 Li-ion cells are a great way to
power Projects. Which provides a nominal voltage of 3.7V which is not sufficient for most of the application for let's say you
want to power a BLDC motor with an ESC which requires 9V to start. So we need more voltage which can be achieved by connecting
them in series. We will show you how you can make a 18650 Li-ion Battery Pack with a BMS circuit and all the things you need to
know before you built one!
1. Everything We Need to be Ready for Building a 18650 Battery Pack
1. 18650 Li-ion cells - 18650 batteries are used for powering everything from laptop batteries to electric vehicles. It is a
standardized type of lithium-ion battery, cylindrical in shape and measuring 18mm in diameter by 65mm in length (give or takea few
1/10s of a millimeter).
2. BMS - A battery management system (BMS) is an electronic system that manages a rechargeable battery (cell or battery pack),
such as by protecting the battery from operating outside its safe operating area, monitoring its state, calculating secondarydata,
reporting that data, controlling its environment, authenticating it and / or balancing it.
3. Plastic Spacer- Replacing the traditional general adhesive with a professional battery holder, the combination is very
convenient, the connection is more firm, and the battery maintenance is also convenient. It is the best choice for battery packs.
It makes building battery pack much less painful.
4. Spot welder - One of the purposes of spot welding is to join 2 or more components together in a mainly permanent fashion. you
can buy one or built one.
5. Nickel Ribbon - Nickel ribbon is commonly used in battery building due to its ease of use in spot welding and soldering as well
its high corrosion resistance over time.
2. Check the Battery and Charge Them Up!
First, we need to check the capacity of all the cells & make sure all the cells are at the same voltage. It is mandatory that all
the cells are at the same voltage else cells will end up charing each other and it can lead to unexpected results.
3. Calculations for the battery pack voltage and capacity
18650 cell can provide a Nominal voltage of 3.7V, Minimum voltage of 3V and Maximum voltage of 4.2V. So if we consider nominal
voltage, connecting 6 cells in series will give us 22.2V which is a 6S1P Configuration.
4. Building the Pack and Spot Welding
For building the battery pack we need tiny black Plastic spacers which snap like Lego and can be very useful as we don't need to
use adhesive instead. Now make 2 pairs of 6 plastic spacers, Insert the cells in alternation pattern. Now we measured the spacing
between 2 cells and it was about 25mm. So I used Nickel Ribbon marked 25mm on it and used sharp scissors to snap it.
5. Adding BMS
Now we can add and plug and call it for the day but we can also add a BMS which adds over charge, over discharge and some of the
also add Balance charging to the battery pack. we just have to solder it to the battery pack as shown on the board. Also, some BMS
like mine does not offer Balance charging so you need to add and Balance charging connector and You are done!
