13.Lithium battery
1 Safety warning
1.1 Electrodes short circuit is prohibited, do not heat the battery, or throw the battery into water;
1.2 Fully charge the new battery before use;
1.3 Do not mix different brands, different types, different capacities, and old and new batteries;
1.4 The battery combination should not be used in the case of inconsistent capacity saturation of
each single cell to avoid overcharge and over discharge of the cell;
1.5 Battery charging method should use professionally configured charging equipment, do not use
charging equipment at will;
1.6If the battery occurs odour, heating, discoloration, deformation or any abnormal phenomenon
during use, storage or recharging, immediately remove it from the equipment or charger and stop
using it. Please immediately contact our technician department or after-sales department;
2 The following operations are strictly prohibited
2.1 Do not put the battery near heat source, dangerous goods and hazardous material, such as
fire, heater, corrosive chemical or hazardous machinery; store the batteries in cool, dry and well
ventilated places if not used;
2.2 Do not immerse the battery in water or any other liquids, which may cause personnel injury or
property loss;
2.3 Electrodes short circuit is prohibited. Avoid any metal or other conductive objects touching the
positive and negative terminals of the battery. This operation may result in personal injury or
property damage;
2.4 It is forbidden to transport or store batteries together with metals such as tools, cables, etc.
2.5Do not hammer, throw or step on the battery;
2.6 Do not connect the battery with the battery of other type in series or in parallel; this operation
may result in personal injury or property damage;
2.7 Do not operate the whole power system with lithium ion battery protection circuit board or
battery management system in series or in parallel; This operation may result in personal injury or
property damage. If needed, contact our technical department for correct technical support;
2.8 Do not let children or other person lacking of safety knowledge have access to the equipment.
This operation may result in personal injury or property damage;
2.9Do not disassemble, squeeze, puncture, storage at elevated temperature or bake the batteries.
Violent vibration, impact and falls from heights should also be avoided. This operation may lead to
security risks;
2.10 Do not operate the equipment in a location where static electricity and magnetic field is strong.
Or it may damage safety protection device, and lead to potential safety hazard;
2.11 Do not recharge without proper protection device(lithium ion battery circuit board protection,
BMS etc.) or with improper charging device (charger or DC power). This operation may result in
personal injury or property damage.
3 Basic terms and environmental conditions for lithium ion battery
3.1 Basic terms and definitions
3.1.1 Nominal voltage
A suitable approximate value used to indicate the battery voltage;
3.1.2 Rated capacity
The capacity value specified by the manufacturer when the battery is fully charged under specified
conditions;
3.1.3 Actual capacity
The capacity actually discharged when a fully charged single cell is discharged at a specified
current under specified conditions:
3.1.4 Overdischarge
The state when the battery voltage is lower than the discharge cutoff voltage is generally regarded
as the state in which the battery enters the overdischarge state, which generally refers to the state
when the battery voltage reaches 0 V or even the voltage is negative;
3.1.5 Maximum charging voltage
The charging voltage recommended by the manufacturer that should not be exceeded during
charging;
