BMS Basic protection function BMS
Overcharge protection: When the battery is charged, the voltage continues to rise, and the protection board detects that the voltage of any cell is higher than that of the battery Charge protection value, the protection board starts timing immediately, when the time reaches the overcharge protection delay, the protection board turns off the charging MOSTube, charge cut-off, can not charge at this time.
Overcharge protection recovery: After the overvoltage protection occurs on the protection board, the battery voltage drops when the battery is standing or dischargingWhen the protection board detects that the voltage of each section is lower than the overcharge protection recovery voltage, the protection board outputs the signal and starts the charging MOS tube.It can be charged at this point.
Overdischarge protection: When the battery is in the discharge state, the voltage continues to decrease, and the protection board detects that the voltage of any cell is lower than the overdischarge protection Protection value, the protection board starts timing immediately, when the time reaches the over-discharge protection delay, the output signal of the protection board turns off the discharge MOS Tube, discharge cutoff, load lock circuit work, can not discharge at this time.
Overdischarge protection recovery: After the protection board is over-discharge protection, the battery voltage continues to rise when the battery is standing or charging When the protection board detects that the voltage of each section is higher than the recovery voltage of the overdischarge protection, the load is disconnected or charged again at this time, and the protection board outputs Out of the signal, open the discharge MOS tube, at this time can discharge.
Overcurrent protection: When the battery is in the static or discharge state, the current suddenly increases. When the protection board detects that the current reaches the overcurrent protection Value, the protection board starts timing, when the circuit current duration reaches the overcurrent protection delay time, the protection board output signal Turn off the discharge MOS tube, the load lock circuit works, and the discharge cannot be performed at this time.
Overcurrent protection recovery: After the discharge overcurrent protection occurs on the protection board, the discharge MOS tube is turned off and the current in the loop becomes 0.now Disconnect the load or charge, the protection board output signal, start the discharge MOS tube, then discharge

The Company promises that if the defects of the battery are proved to be caused in the manufacturing process of our company, the company is responsible for the replacement of the battery for 5 years and will not be replaced if the problem is caused by user abuse or misuse.
Safety warning
In order to prevent battery leakage, heat, explosion, please observe the following precautions:
Don’t put battery into water or seawater, note moist;
Don’t the battery near heat sources, such as fire or heater;
When charging, please use the specific charger;
Don’t reverse battery is negative;
Do not connect the battery in the power of export;
Do not place the battery in fire or hot items;
Don’t across the electrodes of the battery short circuit conductors;
Don’t put the battery and the metal conductor, such as necklace, hairpin, etc connected or stored together;
Do not knock or throw the battery;
Don’t Pierce the battery with pin or other sharp;
Don’t use hammer strike or step on the top;
Don’t direct welding power source;
Battery with safety device, in order to guarantee its inherent security features, please don’t split the battery or change any part;
Don’t charge near the fire or in a hot environment.
Don’t put the battery in a microwave oven or pressure in the closet;
Do not put batteries and other chemical battery (such as dry cell) or pooling of different capacity,brand of battery, if the battery scent, fever, discoloration, deformation, or in the use of charge,storage process, any abnormal please immediately from the device or charger, stop using;
Specify the charging time if can’t charge please do not continue to charge;
Batteries in the children can’t touch place, if children ingest batteries, please immediately go to a doctor;
If the battery leaks or electrolytic gas emit odor, please away from the fire, otherwise leaked solution catches fire, the battery will be on fire;
If the battery leaks or electrolytic into eyes, do not rub eyes, after the application of clean water to rinse the eye doctor, otherwise will cause eye diseases.
Don’t put the battery in high temperature place (such as direct sunlight or heat the world in the car), otherwise, will overheat and fire performance degradation or shorten the life.
Safety device, in order to ensure safety, the battery should be installed in the electrostatic manufacturing when required by the electrostatic when do not use, otherwise, the safety device failure, lead to the battery’s cells from overheating, rupture, explosion and fire.
