  • Lithium-ion battery vs. Lead Acid Battery
    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 the weight and 1/2 of the size compared to 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 ~1000 cycles

    150~300 times


    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.)


    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

    8 ~ 12 hours to fully charge the battery

    Discharge working temperature ℃



    Memory effective



    Thermal stability



    Weight (Compare to the same capacity)

    1/4 of the weight compared to lead acid battery

    comparatively heavier weight


    Any direction

    Upright position is necessary


    Built-in safety protection function

    Danger of acid leakage

    Environmental conform-ability

    Conforms to RoHs standard

    Violates RoHs standard;Lead and sulphate acid are pollutant

    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 special recycling after treatment utility

    Package Contents:

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

    Output Box:
    KF562 Holder & Output Box can be used as a battery holder. You can mount it on the frame vertically or horizontally. The battery then can slide on /off to the output box and locked into place with the key. It is designed for multi-direction installation. You can change the position of battery (vertically / horizontally) by adjusting the clamp.

    LED Display:

    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.

    Output Box (Model# KF562)

    Model No.:KF562B.150
    • Size: 95.00 x 89.00 x 102.00 mm
    • Wire Length: 1500 mm

    Optional Anderson Power Pole Output Connectors:
    The default output connections are two bare wires. We also offer optional Anderson Power Pole connectors as output. You can select this option and we will them for you.

    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.
