Product Description
48V 20ah Li-ion lithium battery with charger for electric bike Electric Bike, Vehicle, car, golf car.

1. High quality long life Li-ion or LiFePO4 storage battery pack
2. Factory located: Jiangsu of China
3. Quality: A team is composed of hundreds QC inspectors to control the progress quality.
4. Application: Solar energy system, UPS, electric vehicle, electric bike, e-tool, electric forklift, etc.
1Safety: Currently the safest li-iron battery, CE UL approved, none fire, none explosive.
2. Environment friendly, no toxic material contained.
3. Long life cycle, more than 600 cycle in 0.5C-1C discharge.
4. No memory effect: Can be recharged any time, no reduction of capacity.
5. Broad operation temperature -20---70 centigrade.
6. Small in size and light in weight.: Compare with SLA battery, 1/2 size of lead acid battery, 70% size of Ni-MH Ni-CD battery. 1/2 weight of lead acid battery.
The features of the lithium electric motorcycle batteries:
1, Safe: The Li-ion lithium electric motorcycyle battery is more safe and reliable than the lead acid one. It does not explode or burn when bump, heavy stress, needle pricking, short circuit, overcharge and overheat.
2, Environment-friendly: Accredited with CE, with out any hazardous and noxious substances.
3, Small in volume and light in weight: The iron-lithium electric battery is about 1/2 the volume and 1/3 the weight of the lead-acid battery.
4, Steady performance: High power output, 1C continuous, 3C pulse for normal cells and 20 C for special design. Low self-discharge rate, less than3%monthly.
5, Long cycle life: Over 1500 cycles with capacity staying at 80% min.
6, Lower average price per year: The average price per year is less than the lead-acid battery.
7, No memory effect: Always ready for charge and use, with no need to charge after a full discharg.
7, Wide temperature range: Available for use when the temperature ranges from 20° C to -70° C.
9, Intelligent charge system: Voltage of each cell can be detected, each cell can be protected against overcharge, overvoltage, short circuit and overheat, and so that battery can be charged balance. The capacity of readout power volume: Each battery has 5LED lights to readout the capacity of the battery.
