SAFETY INSTRUCTIONS
WARNING! Risk of injury
·Batteries contain aggressive and caustic acids. Avoid battery fluid coming into contact with your body. If your skin does come into contact with battery fluid, wash that part of your body thoroughly with water. If you sustain any injuries from acids, contact a doctor immediately. ·When working on batteries, do not wear any metal objects such as watches or rings. LiFePO4 batteries can cause short circuits which can cause serious injuries. ·Only use insulated tools. ·Do not place any metal parts on the battery. ·Wear goggles and protective clothing when working on batteries. Do not touch your eyes when working on batteries. ·Do not use defective batteries.
WARNING! Health hazard
Keep the battery out of the reach of children.
CAUTION! Electrocution hazard
· Keep the battery away from water. · Avoid short circuits. · Avoid clothing rubbing against the battery. · Wear antistatic clothing when handling the battery.
CAUTION! Explosion hazard
· Do not place the battery in a area with flammable liquids or gases. · Never attempt to charge a frozen or defective battery. Place the battery in a frost- free area and wait until the battery has acclimatised to the ambient temperature. Then start the charging process. · Do not smoke, use an open flame, or cause sparking near the engine or a battery. · Keep the battery away from heat sources.
-03-

NOTICE! Damage hazard
· Only use rechargeable batteries. · Prevent any metal parts from falling on the battery. This can cause sparks or short-circuit the battery and other electrical parts. · Ensure that the polarity is correct when connecting the battery. · Follow the instructions of the battery manufacturer and those of the manufacturer of the system or vehicle in which the battery is used. · If the battery has to be removed, first disconnect the ground connection. Disconnect all connections and all consumers from the battery before removing it. · Recharge stored batteries regularly. · Do not carry the battery by its terminals.
Safety precautions when handling lithium batteries CAUTION! Risk of injury
Only use batteries with integrated battery management system and cell balancing.
NOTICE! Damage hazard
Avoid deep discharge of the batteries.

WARNING! Damage hazard
·Refer the connection diagram to connect battery pack in parallel. ·A maximum of 4 batteries in parallel. ·Fully charge each battery pack separately or the max difference voltage between battery packs is within 1V. When multiple batteries are used in parallel, each individual battery should be fully charged or fully discharged separately to ensure that the voltage difference between each battery pack is as small as possible, and then connected in parallel. ·When multiple battery packs are used in parallel, the total charging surge current of the charger may be applied to a single battery pack. It should be ensured that the total charging surge current of the charger does not exceed the maximum charging surge current of a single battery. ·When connecting battery with cables, make sure not to reverse the polarity of the connections. If it is indeed connected incorrectly, the BMS may be damaged. It needs to be retested and qualified before use. ·Battery parallel precautions: It is strictly prohibited to connect battery packs of different brands, models and specifications in parallel. Battery cables connected in parallel must have the same length and specifications, and the busbar must have sufficient current carrying capacity.
Charging WARNING! Damage hazard
·Do not hot-swap the battery pack connection with RV system unless necessary, it will cause surge current. ·Do not charge with higher current than recommended value. It will damage the battery electrical, mechanical and safety performance and could lead to heat generation or leakage. ·Charging current should be less than maximum charging current. ·Charging voltage should be less than 28.8V. Charging beyond this absolute maximum voltage is strictly prohibited. ·The battery should charged within the charging temperature range. ·Reverse charging is prohibited.
-09-

·The battery should be connected correctly and the polarity to be confirmed before wiring. ·In case the battery is connected improperly, the battery cannot be charged. ·The reverse charging may cause damaging to the battery which may lead to degradation of battery performance and damage the battery safety and could cause heat generation or leakage.
Discharging
·The battery should be discharged at less than the maximum discharge current. High discharging current may reduce the discharging capacity significantly or cause over-heat. ·The battery should be discharged within the discharging temperature range. ·To prevent over-discharging, the battery should be charged periodically to keep about 40-50% charge. ·Over-discharging may cause loss of battery performance, characteristics or battery functions. ·The charger prevent the battery to be further discharged beyond the end-of-discharge voltage.
CLEANING
The lithium batteries are maintenance-free. Occasionally clean the product with a damp cloth.

STORAGE

The battery is in transit, and SOC is about 30% by air shipment, about 50 % SOC by sea shipment. The storage environment requirement is as follows:

Storage Temperature
Recommended Storage Temperature

-22 ~ 131°F 90RH Max Less than 1 month

14113°F 90RH Max More than 3 months

5095°F 85RH Max

the battery life would be reduced if battery is stored in high temperature.

If you want to store it for a long time (more than 3 months), store it in an environment where the temperature ranges from 50°F to 95°F @ 85% RH Max and does not contain corrosive gases. Charge and discharge it every 3 months and keep the SOC between 40-50%.

TROUBLESHOOTING

Problem
Battery cannot discharge

Possible cause

Suggested remedy

·Protection against over-temperature. (cell temperature is higher than 149°F) ·Protection against under voltage protection. ·Protection against over current protection. ·Battery output terminal is short circuit. ·System failure.

·Regulate battery pack discharge ambient temperature lower than 122°F ·Charge battery ·RV discharge power is over load, should decrease discharge power ·Check the connection wire and try charge battery ·Shutdown system and check the RV system function
