It may explode. It is very dangerous for lithium batteries without protection board. The circuit board inside is a lithium-ion battery protection board. Its main function is protection against overcharge, overdischarge and overcurrent. When when the battery is charged to a certain voltage (fully charged), the protection plate activates, stops charging and provides overcharge protection, because lithium batteries tend to heat up when charging if it there is no protection plate and the battery is charged. all the time, the heat will be too high and could cause an explosion. Over-discharge protection, that is, when the battery voltage is lower than a certain voltage, the protection board works, over-discharge protection occurs, and the battery stops discharging (stops discharging). 'power the phone portable). This requires charging to avoid). excessive discharge of the lithium battery and causing battery usage. Generally, when the lithium-ion battery voltage is lower than 3V, over-discharge protection occurs, which will prevent the battery voltage from falling below 3V. Over-current protection aims to prevent the positive and negative poles of the battery from being short-circuited and causing large currents that can damage the battery.
No, the circuit board is used to protect the lithium battery from overcharging. and over-discharge, and lithium batteries are most afraid of this. In the latter two cases, if you remove the protective plate, it will have a significant impact on battery life. In severe cases, it will cause battery failure or even explosion. . If you really want to charge it for a whilemps, it doesn't matter. You have to seize the time. It is better to use balanced charging.
