48V 20Ah Forklift Power Lithium Battery for Industrial Vehicle

Precautions for battery operation
1. Prohibition short circuit
Never short circuit battery. It generates very high current which causes heating of the battery and may cause leakage, gassing or explosion that is very dangerous.The poles may be easily short-circuited by putting them on conductive surface.Such outer short circuit may lead to heat generation and damage of the battery.An appropriate circuitry with PCM shall be employed to protect accidental short circuit of the battery pack.
2.  Prohibition Parallel or string battery
3. Mechanical shock
Falling, hitting, bending, etc. may cause degradation of battery characteristics.
4. Prevention of short circuit within a battery pack
Enough insulation layers between wiring and the cells shall be used to maintain extra safety protection.The battery pack shall be structured with no short circuit internally, which may cause generation of smoke or firing.

    hoffumStoring the Batteries

    The batteries should be stored at room temperature, charged to about 30% to 50% of capacity.We recommend that batteries be charged about once per half a year to prevent over-discharge.
