Use special lithium battery protection chip, when the battery voltage reaches the upper limit or lower limit, the control switch device MOS tube cut off the charging circuit or discharging circuit, to achieve the purpose of protecting the battery pack. Characteristics: 1. Only over-charge and over-discharge protection can be realized.
Hardware-type protection board: Use special lithium battery protection chip, when the battery voltage reaches the upper limit or lower limit, the control switch device MOS tube cut off the charging circuit or discharging circuit, to achieve the purpose of protecting the battery pack. Characteristics: 1.
When the lithium battery is used in PACK, it is more likely to over-charge and over-discharge, which is caused by the consistency difference of the cell. If the charging and discharging process is not properly controlled, it will be further increased, resulting in the phenomenon of over-charging and over-discharging of part of the cell.
Lithium batteries are equipped with built-in protection circuits designed to prevent overcharging or low temperature, as mentioned earlier. Battery with low temperature protection, like LiTime cold weather batteries. When the temperature is below 0°C (32°F), the BMS will cut off the charging.
Because of the material characteristics of the lithium battery itself, it can not be over-charge, over-discharge, over-current, short-circuit and ultra high or low temperature charge and discharge, so the application of lithium battery always needs a protection circuit.
Sometimes, faulty or damaged charging cables or ports can prevent a lithium battery from charging. Check the cable and port for any signs of damage or wear. If you notice any issues, replace the cable or repair the port to establish a proper connection between the charger and battery. 4. Battery protection mechanisms engaged

How To Choose A BMS For Lithium Batteries
In this example, we will consider a 7S lithium-ion battery running a 24-volt AC inverter. A 7S lithium-ion battery has a fully charged voltage of 29.4 volts and a dead voltage of about 18.5 volts. Drawing a 1100W load from the battery pack will require around 37 amps when the battery is fully charged. 1100 watts ÷ 29.4 volts = 37.4 Amps
