How to make a drone battery?

How to make your own drone battery The battery used by drones is not a lithium polymer battery, but an 18650 battery. The battery has good performance and will not overheat. Almost unable to work, the battery will supply 22 amps of constant current and 35 amps of transient current. Here's how to make your own drone battery! The first step: Collect the following materials to make your own drone battery 18650 battery, balance connector, silicone wire, R/CXT60 battery connector cable, 6.0 mm for electronic DIY XLPO heat shrink tubing, solder and soldering iron. Step 2: Measure the length of the line of self-made drone battery minus (black line) 6.5 cm, add (red line) 16.5 cm, but if you want, you can lengthen them. Step 3: Carefully peel off the rubber end of the homemade drone battery. Remove about 0.5 cm of silicon insulating material from the end, and flatten the welding wire. Be careful not to cut the wires directly, because thin wires are easy to cut. Step 4: Cut two 2.5 cm long wires to make your own drone battery. These are connected to the battery. These batteries are connected to 1-2 batteries and 2-3 batteries. Step 5: Glue the batteries together and make your own drone batteries to ensure that the batteries are arranged neatly and close to each other, and then apply hot glue on the sides of the batteries. Step 6: Prepare to weld the battery to make your own drone battery. Polish each terminal with sandpaper. You can also make it rough with a knife. This step is to ensure welding safety. Any dirt and grease on the terminals must be removed before soldering. I recommend using very pure alcohol. Step 7: Weld the self-made drone battery and be careful not to overheat, otherwise the battery will be damaged. As shown in the picture, weld the balanced cable. You can also solder the batteries together, but most people don’t have access to the batteries, and I find that the soldering works very well. Step 8: Solder the XT60 connector to solder the homemade UAV battery to the XT60 and heat shrink the surrounding solder. Be careful with the wires, as they can short-circuit and damage the device and battery. Step 9: It is very important to insulate homemade drone batteries to prevent short circuits. Ideally, you should use some shrink wrap, but I don’t have any insulating tape, you have to do this. Step 10: Rebuild the self-made drone battery. The battery weighs 144 grams. Finally, domestic UAV batteries have certain risks, and some flight tests must be carried out before use. In addition, non-professionals should not try to make their own drone batteries, so as not to damage the drone batteries.
