You need to purchase a special lithium battery charger. If you use 2S, 3S, 4S... you need to balance the load. If you only charge one battery, just charge it directly. after purchasing the charger.
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.
It is recommended to purchase a balanced charger for charging.
With four wires, the voltage between two adjacent wires is 3.7V and the voltage between the two ends is 11.1V.
You can try charging directly by connecting them at both ends.
Note:
1 The internal resistance of the battery special lithium islow, pay attention to damaging the transformer.
2 If it exceeds the load, the lithium batteries are directly damaged. They will not be released as heat like nickel-metal hydride batteries.
3 If you. feel a little grease while charging, be careful not to refill it, otherwise it will burn
First of all, you need to make sure your charger meets the standards. Model airplanes must use a dedicated charger.
While you can settle for a simple balanced charge, you should also choose a brand with better quality and reputation.
Generally, excessive overshoot and excessive discharge can cause air swelling. Too high charging voltage and too large current can also cause air swelling. It is normal for model aircraft to have air bulging during use. As long as you pincez, you can still pinch the polymer from the battery core and continue to use it.
Although the air drum explodes, it will not cause much damage, but it will make a loud noise, like a balloon exploding. You also need to be careful of toxic gases, but it's not a big problem, as long as they don't overheat and spontaneously ignite, it won't be a big deal.
Never try to deflate it. If it is deflated, the battery will die.
