Description

48V High Capacity (11.6Ah or 557h) Lithium Ion Battery for electric bicycles.

High Capacity: 11.6Ah (557 Watt-hour), equivalent to a 12V 45Ah Sealed Lead Acid battery.

Light Weight: weighs 7 pounds. ( A equivalent capacity Sealed Lead Acid battery may weigh around 30 pounds.)

Small Size: 15" x 4.5" X 3.5, can fit in many different places.

Very Powerful: continuous output up to 450-550W, maximum burst output up to 600W.

High Quality: Made with high quality Panasonic Lithium Ion cells.

High Durability: Water-resistant and firm ABS plastic casing. The internal pack is stabilized by braces that can avoiding mechanical accidents caused by vibration.

High Safety: Built-in PCB protection to prevent short circuit, over-current, over-heat, over-charge, over-discharge.

This battery is for professional users with advanced electric knowledge only. We are not responsible for any damages or losses caused by using the battery pack. Please read Battery Safety Information & Guidelines and our Terms & Policies before ordering this battery.

Output Voltage: 39V ~ 54.6V, Nominal Voltage: 48V;
Maximum Continuous Output Current: 15A
Maximum Burst Output Power ( up to 10 miutes) Current: 18A.

This battery output voltage range is 39V ~ 54.6V. Nominal output voltage 48V. When the battery is fully charged, its output voltage is 54.6V. The output voltage will drop gradually during the discharge process and the final cut off voltage is 39V

Battery comes with a mount rail with key lock.

Charge Ports: The battery itself has a charge port. The Mount rail also has a charge port. When battery is on bike, you can charge it from mount rail port. If you remove battery from bike, you can charge it from home and office from charge port on battery.

Safety Features:

Water-resistant and firm ABS plastic casing.
Built-in PCB protection.
Prevent short circuit, over-current, over-heat, over-charge, over-discharge.
The internal pack is stabilized by braces, thereby avoiding mechanical accidents caused by vibration.

Lithium-ion battery vs. Lead Acid Battery

Although this battery is rated as 626 Watt-hour, theoretically its capacity is equivalent to a 12V 55Ah Sealed Lead Acid battery. However, since lithium batteries can be fully discharged while most lead acid batteries cannot, this battery's actual output capacity may be close to a 12V 60Ah ~ 65Ah lead acid battery.

Using a lithium-ion battery offers many advantages over older SLA (Sealed Lead Acid) batteries because of lithium-ion's high energy density, small size, and low weight. A typical lithium-ion battery has 1/4 of the weight and is 1/2 of the size of a same capacity traditional heavy bulky Sealed Lead Acid battery.

Battery Type	Lithium ion Battery	Lead Acid Battery
Voltage fluctuation in working	Remains stable with different output	Voltage fluctuation based on output
Cycle life (Residual capacity over 5%)	500 ~700 cycles	150~300 times
Capacity	Very stable and very little affection by output current	Suffer a big affection in by output current. Capacity will be much smaller than rated capacity when output current is large.
Depth Of Discharge (D.O.D.)	99%	50-60%
Self discharge rate (per month)	1~1.5% (Capacity remains over 80% even the battery is idled for one year)	30% (Battery capacity drops near to zero if it is unused for 3 months)
Fast charge capability	Charge to full capacity in about 6 hours	needs 8 ~ 12 hours to fully charge the battery
Discharge working temperature ℃	-20～+75	-20～+55
Memory effective	None	None
Thermal stability	Outstanding	Acceptable
Weight (Compare to the same capacity)	1/4 of weight to lead acid battery	comparatively heavier weight
Installation	Any direction	Upright position is necessary
Safety	Built-in safety protection function	Danger of acid leakage
Environmental conform-ability	Conforms to RoHs standard	Violates RoHs standard；Lead and sulphate acid are pollutants
Disposition of used battery	Lithium-ion batteries are generally not considered an environmental hazard because they do not contain lithium metal. The United States government labels them as non-hazardous waste and does not oppose them being discarded together with the trash that makes up the local waste stream.	Needs to be specially recycled after treatment utility

Package Contents:

The battery comes with a AC charger and mount rail. The AC charger can charge the battery from any 100V ~ 240V AC power source.

Warranty: One Year limited warranty. The one year limited warranty covers manufacturing and quality defects only. Please note that batteries wear out with use. The amount of charge a battery can hold gradually decreases due to usage and aging, which is normal, and this is not the issue covered by warranty.
