Making your own battery pack can be a great way to save money and get exactly the features you want. This guide will show you how to make a lithium battery pack with 18650 cells. You’ll need a few tools and materials, but it’s not as difficult as it might seem.
You’ll need a soldering iron, some solder, heat shrink tubing, and of course, the 18650 cells. You’ll also need a battery charger, since you’ll need to charge the cells before you use them. Once you have everything, you can start soldering the cells together.
Start by soldering two cells together positive-to-negative. Then connect the two pairs of cells together, again positive-to-negative. Once all the cells are connected, you can solder on the positive and negative terminals. Make sure to cover the terminals with heat shrink tubing to avoid shorts.
Now you have a completed battery pack! You can use it to power just about anything that uses 18650 cells.
So, how to build your own battery pack?
If you want to build your own battery pack with 18650 cells, you’ll need to start by connecting the cells together in series. Once you have all of the cells connected together, you’ll need to add a connector to the end of the pack so that you can connect it to your device. Finally, you’ll need to add a protection circuit to the pack to prevent the cells from being overcharged or discharged too deeply.
Let’s dig into it and find out what’s going on.
Step By Step Process On: How To Build Your Own Battery Pack?
Here I will explain you step by step process of how to build your own battery pack? let’s see how to build your own battery pack.
First of all, you need six Lithium-Ion batteries of INR 18650-25R type. These batteries have a capacity of 2500mAh each. You will need to place three of these batteries in series in order to get 12.6 volts when fully charged and 7.5 volts when completely discharged.
In addition to that, you will need to add a second battery to each cell in parallel in order to double the overall capacity of the battery pack. So, in the end, you will have a 3S2P battery pack with an energy of 55.5 watt-hours. This will be enough to power 5 meters of the LED strip for 1.6 hours.
Now, in order to connect these cells properly, you will need a bit of Nickel Ribbon. The ribbon should be 5mm wide and 0.15mm thick in order to carry the required 3 amps for the LED strip.
There are two ways to attach the ribbon to the batteries. The first and recommended way is to use a spot welder which utilizes a burst of energy in a very short amount of time to weld the ribbon to the battery. However, if you do not have access to a spot welder, you can solder the ribbon to the battery terminals.
Before soldering the ribbon to the batteries, you will need to measure whether the voltage of the parallel cells is close to one another. Otherwise, one of the cells could end up charging the other one with an unhealthy amount of current.
Once you have confirmed that the voltages of the parallel cells are close to one another, you can proceed to soldering the ribbon to the battery terminals. To do this, you will need to create a shorter length of the nickel ribbon and tin both sides of the ribbon.
After tinning the ribbon, you will need to abrade the positive and negative terminals of the batteries with sandpaper in order to create a good connection. Once the terminals are prepared, you can solder the ribbon to the terminals.
After soldering the ribbon to the battery terminals, you can proceed to inserting the batteries into the designated spacers and connecting them in parallel. Once all the batteries are connected, you can proceed to connecting the

Now, fold the foil over the lithium strips and seal it up. You can use tape, glue, or even staples to do this.
Finally, connect the two ends of the battery with a wire. This will complete the circuit and allow the battery to work.
That’s all there is to it! With just a few simple materials and some basic instructions, you can make your own lithium batteries at home.
How Many 18650 Cells Do I Need For My Battery Pack?
There’s no easy answer to this question as it depends on a number of factors, such as the capacity of the cells, the voltage of the pack, and the discharge rate. However, we can give you a rough guide to help you calculate the number of 18650 cells you’ll need for your battery pack.
The capacity of 18650 cells is typically between 2,000 and 3,500mAh. To calculate the number of cells you’ll need for your pack, simply divide the total capacity of the pack by the capacity of the cells. For example, if you have a 10,000mAh pack, you’ll need 3-4 18650 cells.
The voltage of 18650 cells is typically between 3.6 and 4.2V. To calculate the number of cells you’ll need for your pack, simply divide the total voltage of the pack by the voltage of the cells. For example, if you have a 36V pack, you’ll need 9-10 18650 cells.
The discharge rate of 18650 cells is typically between 20 and 30A. To calculate the number of cells you’ll need for your pack, simply divide the total discharge rate of the pack by the discharge rate of the cells. For example, if you have a 100A pack, you’ll need 3-4 18650 cells.
As you can see, there are a number of factors to consider when calculating the number of 18650 cells you’ll need for your battery pack. However, by using the simple formulas above, you should be able to get a good estimate of the number of cells you’ll need.
You will need: – 18650 cells (I used SanyoGA 18650 cells) – A spot welder (I use the Yihua 936) – Nickel strips – Solder – Heat shrink tubing – A container for your battery (I use an old Altoids tin) – A BMS (Battery Management System)
The first step is to weld the nickel strips to the 18650 cells. This will be the positive and negative terminals for your battery pack. Make sure that the welds are strong and secure.
Next, solder the wires to the nickel strips. I like to use red and black for the positive and negative respectively.
After that, it’s time to add the heat shrink tubing. This will help to insulate the battery and prevent any shorts.
Now, it’s time to add the BMS. This is an important step as it will balance the cells and prevent overcharging.
Finally, add the cells to your container. I like to use an old Altoids tin, but you can use whatever you have on hand. Make sure that the lid is secure and that there are no exposed wires.
