The 3c11.1v lithium battery of the model airplane can be charged through the discharge hole. The battery discharge port is transmitted to the motor via the circuit board. We charge the battery directly at the battery discharge port without going through the circuit board. Lithium battery is a type of battery that uses lithium metal or lithium alloy as positive/negative electrode materials and uses non-aqueous electrolyte solution. Lithium metal batteries were first proposed and studied by Gilbert N. Lewis in 1912. In the 1970s, M.S Whittingham proposed and began studying lithium-ion batteries. Since the chemical properties of lithium metal are very active, the processing, storage and use of lithium metal have relatively high environmental requirements.
You need to purchase a special lithium battery charger. If you use 2S,3S, 4S...you need a balanced charge. If you are only charging one battery, charging it directly is sufficient. charger. There will be instructions later.
If you don't buy a charger, you can also use a mobile phone charger to charge. You need to solder a battery head yourself and charge it piece by piece. . The output voltage of the mobile phone charger is 5V higher than the battery saturation voltage of 4.2V, otherwise the battery will be easily damaged.
I hope you are satisfied!
