Important: This battery is designed for independent use only. Do not connect this battery with another battery directly in serial or parallel. Connecting this battery with another battery may damage the battery's safety protection and power management circuit board.Features: Built-in charge and equalizing protection board to prevent battery from over-charging Remarkably low self-discharge for extended storage periods up to 2 years. More than twice the service life of conventional lead acid batteries No corrosive liquids, nor toxic heavy metals make the Li-On batteries environmentally friendly Super lightweight: only 3.3 kg (7.3 pounds), less than the 1/4 weight of a similar lead acid battery. Fast 6 hour charging time When using this charger, the battery can still output power while it is charging. This battery output terminals are separated from charge port. Charge battery from charge port only. Do not charge the battery from output terminals. The charger will control charging voltage and current. Internal circuit will provide over charge and over discharge protection, but will not control charge voltage and current. Applications:1. Directly use this battery to provide power:This battery output voltage range is 21V ~ 29.5V. When the battery is fully charged, its output voltage is 29.5V. The output voltage will drop gradually during the discharge process and the final cut off voltage is 21V:Only use this battery with devices that can accept every voltage in the 20-30V range and require 500W or less power. 2. Use this battery with a DC to DC converter to to provide different voltagesThis battery output voltage range is 21V ~ 29.5V. This output voltage can be converted to different voltages to meet different needs by using DC to DC power converters.3. Use this battery with a DC to AC Power Inverter to provide 110V or 220V AC power This battery's output voltage range is 21V ~ 29.5V. You can use a 24V DC to AC Power Inverter to convert DC power to 110V or 220V AC power.4. Use the single 24V lithium ion battery to replace two 12V lead acid batteries connected in serial:You may use this single 24V lithium ion battery to replace two 12V lead acid batteries connected in serial. This battery is perfect for devices that need up to 500W power, such as 24V motors in electric scooters and electric wheelchairs. TECHNICAL SPECIFICATIONS Battery Type Lithium Ion Nominal Output Voltage 24V Output Voltage Range 20V ~ 29.7V Capacity 576 Watt-hour ( 24Ah @ 24V) Maximum Continuous Discharge Current 20 A Maximum Burst Discharge Current 30 A ( up to 10 minutes) Size 180 x 170 x 75 mm ( or 7" x 6.8" x 3") Weight 3.3 kg ( or 7.3 pound, ) Operate Temp.
