These batteries can be charged 300 to 500 times and they have an internal circuit to stop the charging process at full charge. Also cant be over discharged. A lithium polymer battery using the polymer electrolyte composition can be suppressed from danger of ignition or explosion when the battery is overcharged due to some uncontrolled conditions such as failure of a charger.
The state of charge SOC for step 1 reaches only 85 charge and it is the most recommended level for Li-ion charging.
Since safety hazards can occur during the life of a Li-ion battery understanding its behavior under abusive conditions is important for the development of a safe cell. In a lithium-ion battery overcharging can create unstable conditions inside the battery increase pressure and cause thermal runaway. So if you accidentally run your planecar too. But they can go up in smoke when bad things happen.
