If you are a beginner and want to determine how to choose a battery that matches your skateboard, first you need to know what you plan to use an electric skateboard for. Not only is this the most expensive part of any DIY build, but it also affects speed and distance.
You need to consider your riding style, the speed you want to achieve, and the range you want to achieve. These will save you a lot of trouble in the future. Read this article with these needs and wishes.
Lithium polymer batteries(Lipo) have a reputation as a cheap power source for most electric skateboards. They are suitable for almost any housing setup and are perfect for custom AT or competition versions where you are trying to get a lot of power and ground clearance at the same time. Lithium polymer batteries are very sensitive to puncture and may burn and explode if not handled properly, so you must respect them.
There are several different configurations of lithium-ion batteries. The 18650 battery only means that each battery in the battery pack has a diameter of 18 mm and a length of 65 mm. All batteries are either in parallel or in series.
Parallel (P): The positive pole is connected to the positive pole, and the negative pole is connected to the negative pole. Then, the connected battery basically becomes a larger battery with the same voltage but double Ah.
Series (S): A battery that connects one positive electrode of one battery to the negative electrode of the next battery. This will increase the voltage of the battery, thus providing you with more power.
So to sum this up neatly, a battery with more cells in Parallel will have a longer range, and batteries with more cells in Series will have more power and speed.
What are the most common electric skateboard batteries?
At present, the most common are 36v – 48v batteries in the range of 6 to 12 S, of which 1 to 4 P is the most standard parallel setting. All batteries have two battery styles in their design. For example, a 10S4P battery, it just means that you have 10 batteries in series and 4 batteries in parallel.Of course, when you create a battery, you can add any number of batteries. Just make sure that any ESC you choose to use can handle battery power.
Can you charge the battery?
Yes it is. You can separately purchase a balanced charger to charge different batteries. Every time you charge the battery, you are fixed in a charging cycle. If you are not afraid of overcharging, you can use a battery level indicator, which is very simple. A good rule of thumb is to not let the battery charge drop below the 50% full threshold when storing the circuit board. It is never recommended to completely drain the battery.
A short note about the battery box
Although most parts can be purchased online, the battery and ESC case are still a feature of most customized versions. No matter what kind of case you build or buy, you need to make sure that there is enough space to place the battery in the case and a little space for the circuit board to bend. Or use heat shrinkable film to fix the battery.
Regarding which battery is suitable for which application, as electric skateboards become more and more popular, new innovations will continue to appear, so please follow the DIY trend so that you can rotate when new technologies become available.
