3.5.1. Safety Instructions for Battery Use, Store and Charging
Please OBEY These Precautions for Battery use and Charging
o Always wear protective gear when handling batteries
o Use a wrench with a rubber coated handle.
o Do not place any objects on top of batteries.
o Do not place batteries on a metallic surface.
o Check the cable is in good condition.
o Make sure all cable connections are properly tightened.
o Keep sparks, flames, and metal objects away from the battery.
o Have a fire extinguisher of the following type: a foam extinguisher, CO2, ABC dry
chemical, powdered graphite, copper powder or soda. (sodium carbonate) on the
premises
o The battery should be stay inside the fireproof and explosion-proof lithium battery
bag when using, charging, and storing.
o The battery MUST be securely fastened to the trolley’s battery seat with battery
straps.
o Don’t impact or drop the battery. No longer use the battery, if it has been punctured,
crashed or water damaged.
o Please do not disassemble the battery or throw it into a fire. EXPLOSION!!!
o Never touch the electric poles of the battery!! Safety hazard!!
3.5.2. Battery Charging Instructions for LFP Lithium Batteries
3.5.2.1. When to Charge your LiFePO4 Battery
If LiFePO4 batteries are not fully discharged, they do not need to be charged after each
use. LiFePO4 batteries do not get damaged when left in a partial state of charge (PSOC).
You can charge your LiFePO4 batteries after each use or when they have been discharged
up to 80% (20% SOC). If the BMS disconnects the Battery due to low voltage, at 100%
depth of discharge, remove the load to reconnect the Battery circuit and charge
immediately. You must use a LiFePO4 Battery charger in order for the BMS to reconnect.
3.5.2.2. Charging Temperature
Lithium Iron Phosphate batteries generate a fraction of the heat of other lithium
chemistries when charging, making them very safe. LiFePO4 batteries can safely charge
between 0°C to 45°C (32°F to 113°F).
LiFePO4 batteries do not require temperature compensation for voltage when charging at
hot or cold temperatures. The LiFePO4 comes with a BMS that protects the battery from
under-temperature and over-temperature. If the BMS disconnects due to low temperature
while charging, the Battery must warm up for the BMS to reconnect and continue charging.
If the Battery disconnects due to high temperature, the BMS will not allow the Battery to
