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 cable. The AC charger can charge the battery from 100V ~ 240V AC power source.

Battery Charging:

Battery can be recharged  with the provided  battery AC charger.

Output Port:

The output cable  provide output  with 2 wires: one wire is +24V, one wire is ground.

On / Off Switch:

The battery has a On /Off switch. The LED at on/off of the battery glows when power is on.

 
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.
• - Avoiding mechanical accidents caused by vibration.

	Battery can be installed and removed easily by using the easy-carrying handlebar.		Battery can be recharged either by fastening on the bike or by itself with the provided AC adapter.
	The Four-level LED indicates current power status.		The LED at on/off of the battery glows when power is on.
	The 15A fuse, serves as a second protection device, can prevent the battery pack from excessive discharge.		The multi-pole circular connector enables effective and proper battery contact.
