Handle the battery gently during use to avoid damaging internal components 2. The use of batteries in series or parallel is prohibited; Causing malfunction that cannot be guaranteed 3. The battery should be placed inside the battery casing without any looseness, shaking, compression deformation or other adverse phenomena 4. It is strictly prohibited to insert the positive and negative wires of the battery into each other, reverse connect the load, or connect them to mismatched electric vehicle loads 5. Unauthorized disassembly is strictly prohibited during use. Unauthorized disassembly does not provide warranty, and returns are refused 6. It is strictly prohibited to place the battery next to a heat source or high-temperature source (such as fire, heater, etc.) for use and retention 7. The battery is rainproof, but please do not place it in water in contact with water, as water ingress does not guarantee it; Store in a cool and dry environment when not in use 8. It is necessary to use a matching charger for charging, and it is strictly prohibited to use lead-acid battery chargers as they may cause damage or damage 9. It is recommended to keep the charger at home as carrying it with the vehicle may cause internal components to become loose due to shaking 10. The charger is only guaranteed for 6 months (the buyer needs to bear the round-trip shipping cost) 11. Follow national regulations and do not charge indoors to avoid accidents. 12. When purchasing, please choose the same voltage as before. If different voltage causes problems, no insurance will be provided About Charging 1. It is necessary to use our company's specialized or certified charger for charging, otherwise it may result in short battery life, battery failure, and termination of warranty services; 2. It is prohibited to directly contact the positive and negative terminals with conductive objects 3. Please charge the battery within 0 -40 . For daily use, the charger can be charged as needed 4. When the battery leaves the factory, it only has a small amount of power. Please fully charge the battery before use 5. In order to ensure your life safety, it is strictly prohibited to bring it home or charge indoors, and it is strictly prohibited to charge in unattended areas; When charging, please place the charger and battery in a ventilated, stable, dry, open and safe place without flammable or explosive materials, and out of reach of children 6. During the charging process, the charger may generate heat. As long as the temperature does not exceed 60 , it is considered normal. 7. After the battery is completely discharged, it should be charged in a timely manner and the charging time should not be less than 3 hours. 8. During battery storage, the battery should be charged every month About discharge 1. This product can only be used on electric vehicles that match the specified electrical performance and cannot be used on other electrical equipment, otherwise it will not be covered by warranty 2. Damaged or improperly configured controllers, clicks, speakers, lighting equipment, etc. of electric vehicles can lead to high current discharge of the battery. At this time, the battery will protectively stop outputting. After turning off the power and restarting, it can be restored without any impact on your riding experience 3. The applicable temperature range of this product is -10 -45 ; Like all other batteries, as the temperature decreases, the energy utilization of the battery casing decreases, which is a normal phenomenon 4. When using lithium batteries, avoid water, beverages, and corrosive liquids inside the battery, which may cause leakage, heating, smoking, fire, and explosion of the battery 5. It is prohibited to use two or more batteries in series or parallel without au
