Small Size and Light Weight:

This battery only weighs around 3.8 pounds (same capacity Lead-Acid battery will be around 16 pounds). 


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 weightand is 1/2 of the size of a same capacity traditional heavy bulky Sealed Lead Acid battery.

Package Contents:

The battery comes with an AC charger and output box. The AC charger can charge the battery from any 100-240V AC power source. 




Output Box:

The output box can slide into the battery contact socket. Its output cable has 2 wires: red wire is +24V, black wire is ground. 

KF542B Output box: 

If you are using this battery for a e-bike, you may select this output box. This output box comes with a lock for mounting on a bike or other devices.

Size: 95.00 x 89.00 x 59.00 mm (3.7" x 3.5" x 2.3") 

The output box is lockable: if locked, it can not be removed from the battery. If unlocked, it can slide on/off the battery contact socket easily.

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.

	The Four-level LED indicates current power status.		Battery can be recharged either by fastening on the bike or 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 holder.
	Battery can be installed easily. Simply slide the battery towards the holder by following the track		The Output Box KF542 is designed for multi-direction installation. User can change the position of battery (vertically / horizontally) by adjusting the clamp.

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, and this issue is not covered by warranty.
