1.Life expectancy is two times that of lead-acid batteries.The weight is more lighter

2.No memory effect and rechargeable.the battery life is more longer

3.Safer and more environmentally friendly, No heavy metals and hazardous substances.

4.Built-in IC chip will prevent battery pack over charge, over discharge, over-current,

over-heat, short circuit .

5.Avoiding mechanical accidents caused by vibration.

1pcs 48V HaiLong Ebike Battery pack, with BMS.

1.High energy density, Fast charging

2. Light weight, small size  Pollution-free, environment friendly

3. Long cycle life; It extends its cycle life up to 600-800 cycles

4. With short-circuit production function, safe and reliable

5. Large overcharge tolerance and safe performance the batterylife is more longer

6. Simplifying battery management system (BMS such as overcharge/ discharge,over current, short circuit,

over temperature andbalancing) and Battery Charger

Precautions:

1.Do not reverse the position and negative terminals.

2.Do not connect the battery electrodes to an electrical outlet.

3.Do not discard the battery in fire or a heater.

4.Does not use or leave the battery near a heat source as fire or heater

5.Do not short circuit, over-charge or over-discharge the battery pack

6.Do not strike, trample or throw the battery.

7.Do not directly solder the battery and pierce the battery with a nailor other sharp objects

8.Do not short-circuit the battery by directly connecting the positive andnegative terminals with metal objects.

9.Do not transport or store the battery together with metal objects suchas hairpins, necklaces, etc.

10.Use the battery charger specifically for that purpose when recharging.Use a constant current, constantvoltage

(CC/CV) lithium-ion (Li+)batterycharge controller

11.Do not immerse the battery in water or seawater, and keep the batteryin a cool dry surrounding if it stands by.

12.If shelve a long time suggested that the battery need for regular recharging (even if not use),must charge and

discharge for three months one time;
