Battery Features:

12.8V 20Ah Lithium Iron Phosphate (LiFePO4) Portable Rechargeable Battery



High Capacity: This battery capacity is 256 Watt-hour( 12.8V 20Ah)

Light Weight: This battery only weighs 5.6 pounds. A same capacity lead acid battery may weigh 13 pounds

This battery has two Input/Output connectors. You may use them to charge battery or get power from battery. One end is 5.5 x 2.5mm female connector with positive polarity ( Inside positive, outside negative/ground). Another end has two wires with Anderson Power Pole connector. Red Wire is positive, Black wire is negative/ground.

Lithium Iron Phosphate (LiFePO4)Pros:

Long life span (5-10 years) vs lead acid (1-3 years), depending on depth of discharge and assuming that the cycle limit doesn't kill the battery first Longer cycle life, as LiFePO4 batteries last 1,000 to 3,000 charge and discharge cycles, compared to similarly sized lead-acid batteries, which can range from 200 - 1000 cycles (again, assuming depth of discharge is within recommended limits for both battery types).

Very safe - the odds of a "thermal runaway" (aka battery fire) are very low. The same can not be said of other lithium ion chemistry.

Note

The package comes with a DC to DC power converter that can convert battery variable 12V power to 24V regulated stable DC power. The converter output connector is specially designed for ResMed Airsense 11 series CPAP machines.



The DC Converter input side has a barrel connector that can directly plug to battery output port:





You may use the battery independently to power a CPAP machine



You may also charge the battery and power CPAP machine at same time. This will provide a function like a UPS (Uninterrupted Power Supply) system:



This UPS system is very simple to use, just connect battery with AC charger and power Converter together, then connect battery AC charger to a 100V ~ 240V Power source, DC converter to CPAP machine. When AC charger has power, it will charge battery and at same time power CPAP machine. When AC charger has no power, the battery will provide power to CPAP machine. The system can support uninterrupted DC power up to 90W continues output.

This power pack can power ResMed AirSense 11 CPAP machines for 3 ~ 4 nights with the humidifier turned off.

DC Converter Features:

This DC to DC power adapter can convert variable 12V DC (range 9V -32V) to 24V regulated stable DC power. Maximum output 65W

his DC to DC power adapter's input side has 5.5 x 2.5mm barrel connector that can plug to battery directly.

Wide input range: 9V ~ 32V
Output: Max. 65W
Small size: 90 x 36 x 27mm ( or 3.5" x 1.5" x 1.1")
