36V High Capacity (17.4Ah or 626 Wh) Lithium Ion Battery for electric bicycles.

  • High Capacity: 17.4Ah (626 Watt-hour), equivalent to a 12V 55Ah Sealed Lead Acid battery.
  • Light Weight: weighs ~9 pounds. ( A equivalent capacity Sealed Lead Acid battery may weigh around 40 pounds.)
  • Small Size: 16.5" x 6" X 2.6", 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: 30V ~ 42V
    , Nominal Voltage: 36V;
    Maximum Continuous Output Current: 15A
    Maximum Burst Output Power ( up to 10 minutes) Current: 18A

    This battery output voltage range is 30V ~ 42V. Nominal output voltage 36V. When the battery is fully charged, its output voltage is 42V. The output voltage will drop gradually during the discharge process and the final cut off voltage is 30V:

    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


    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.)



    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 ℃



    Memory effective



    Thermal stability



    Weight (Compare to the same capacity)

    1/4 of weight 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 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 output box. 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.
