Using Lithium-ion battery  offers many advantages over older SLA (Sealed Lead Acid) battery  because of  Lithium-ion battery's high energy density, small size, and low weight.   A typical Lithium-ion battery may only has 1/4 of weight and 1/2 of size compare to same capacity traditional  heavy bulky Sealed Lead Acid batter. This battery weight is less than 4 pounds. A same capacity Sealed Lead Acid battery may weigh around 16 pounds.)

Package Contents:

The battery comes with a AC charger and output box. The AC charger can charge the battery from 100V ~ 240V AC power source.


Charging the Battery:

The battery can be recharged by the provided AC charger  from 100V ~ 240V AC power source.

Output Box:


The output box can easily slide on the battery by following the track. The output box provides output wires and a lock: if locked, it can not be removed from the battery. If unlocked, it can slide on/off the battery contact socket easily.

The Four-level LED indicates current power status.

Features:

	The Four-level LED indicates current power status.		The 15A fuse, serves as a second protection device, can prevent the battery pack from excessive discharge.
	It is easy to hold the battery with the well designed handlebar.		Battery can be recharged either by fastening on the bike or by itself with the provided AC adapter.
	The LED (at the power button controls on/off of the battery) glows when power is on.		The key lock is used to fix the battery onto the output box.
	Battery holder can be welded on the bike vertically or horizontally. The Contact of KF541 is also adjustable in order to enhance the flexibility of battery installation.		KF542, the fixed holder, is designed for multi-direction installation. User can change the position of battery (vertically / horizontally) by adjusting the clamp.
	Battery can be installed easily. Simply slide the battery towards the holder by following the track.
