Lithium-Ion Battery Instruction Manual
Warnings
 Never short circuit the discharge or charge terminals of the battery.
 Never charge the battery by discharge terminals or discharge the battery by charge
 Keep the battery away from excessive heat and open flames. Never put the battery into  Never subject the battery to intense physical shock or severe vibration or impact.  Protect the battery from water or other moisture. Protect the discharge and charge terminals of the battery from rain or water logging.  Keep the battery away from children.  Never disassemble the battery without permission.  When the battery is not in use for an extended period of time (more than 30 days), remove  Use only the special charger supplied by our company. Never use other charger to charge General use instructions
1 Charge
 Charge temperature range 0~45℃
 Over charging is seemly improving the battery's capacity, but it wil be danger and shorting
 The higher the charging end-voltage, the higher the charging current, the longer the charging time, the more harmer the battery receives;  If there is any abnormal situation such as the battery transforms and bloats, or becomes  Do not connect the battery and the charger to AC for a very long time.  Do not connect the charger with the AC for a long time unless under the condition of  The charging environment should be dry, wel -ventilated and far away from fire.  There should be no inflammables in 1.5 meters around the battery when it is under  Do not charge around inflammable or dangerous things.  It is better to take out the batteries from containers when charging for abstraction of heat.  Keep away from children when the charger is working to avoid danger. 2 Discharge
 Discharge temperature range -20℃~55℃
 Avoid over discharging. When the voltage of per cell is lower than the limit of cut-off voltage,
the battery is under over discharging condition.  Long time of over discharging wil shorten the life of the battery.  Never charge more ful and discharge more empty wil lengthen the battery life.  Avoid large current or it will affect the battery life.  Accelerate slowly when cycling starting, avoid starting at still, and avoid sudden accelerating  Avoid starting at stil when running up the slope; it is best to use pedal power when  It is better to cycle human-assisting when running up, climbing or heading up.  Speed up slowly or pedal at low temperature.  Avoid flooding the battery by the rain when cycling, which may cause danger.  When the battery is not in use for an extended period of time, remove the battery from the load for storage to avoid self-discharge by load.  Do not lay up the battery when there is no electricity or low voltage. 3 Storage
 Storage conditions for the battery: circumstance temperature 0~30℃,circumstance relative
 The battery should be kept in storage in a clean, dry and ventilated circumstance; it should be avoided to touch with the corrosive substance and should be away from excessive heat and open flames.  The batteries should be kept with 50% of the capacity; storage time of the battery should  The capacity of the Lithium battery will be decline when storage.  The battery should be charged once every 30 days when storage, every time charged about  The battery should be with fireproofing measures when storage together, there should be
safe distance or fireproofing material for isolation.
4 Delivery
 The battery should be packed with insulation and shockproof material, and lined out the
 Avoid the damage from jolting in the way.  The battery should be upward, and should be lined out upward labels. Do not upend, or  The batteries should be handled with care when transport. Never throw the batteries. Avoid  Never put heavy goods on the batteries for transport. Avoid damage of the batteries from  Never transport the batteries with the flammable, explosive, or sharp metal objects.  There should be moisture-proof and fireproof labels on the packing, to avoid danger from  There should be 50% of the battery capacity when transport, and charge ful of electricity at 5、Typical trouble and elimination
The battery has been finished the charging, it can Cannot be charged The overcharge protect function works Check the output plug of the charger whether Cannot be charged Output plug of the charger become flexible connect firmly to the battery Power-down suddenly The overcorrect protect function works The over-discharge protect function works Please charge the battery.
