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.
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:

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.

| 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.
