12.8V 20Ah Lithium Iron Phosphate (LiFePO4) Portable Rechargeable Battery
Features:
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.
Optional Carry Bag:
Multi batteries can be connected in serial or parallel to provide more power:
Most lithium ion batteries can not be connected together directly without extra circuits protection. This battery has built-in circuits inside that make this battery being able to connection in serial ( Maximum 4 batteries allowed in serial) to provide higher voltage, for example, 2 batteries in serial to provide 24V power, 3 batteries in serial to provide 36V power, 4 batteries in serial to provide 48V power. Multi batteries can connected in parallel to provide more power also, for example, 2 batteries in serial to provide 12V 40Ah capacity, 3 batteries in serial to provide 12V 60Ah power.
Warning: Only this battery and some other specially designed batteries can be connected in serial or parallel. Unless specifically mentioned, all other BiXPower lithium ion batteries are designed to provide power independently, can not be connected directly with other batteries in serial or parallel.
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).
LiFePO4 batteries are less susceptible to problems caused by depth of discharge...a LiFePO4 battery can be dropped to 20% of charge without long-term damage. Most lead-acid batteries lose capacity or cycle life if they're discharged more than 50%.
Lighter than lead-acid batteries.
Arguably, LiFePO4 batteries are more environmentally friendly than lead acid.
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.

Output Voltage:
The battery output voltage range is 10V ~ 14.6V, nominal
voltage is 12.8V. When the battery is fully charged, its output voltage
is 14.6V. The output voltage will decrease gradually and finally will
cut off at around 10V. Most of the time, the voltage will be in range 12V ~ 13.6V
Package Content (Battery Only):
Battery Optional AC Charger:
You may order battery with optional 14.6V 6A AC Charger or 14.6V 10A Charger.
 14.6V 6A AC Charger
With 14.6V 6A AC charger, the battery pack can
be fully charged in
less than 4 hours from any 100-240V AC power outlet.
 14.6V 10A AC Charger
With 14.6V 10A AC charger, the battery pack can be fully charged in around 2 hours from any 100-240V AC power outlet.
Cautions: Please
use the BiXPower authorized charger with correct setting to charge the battery
only. Wrong chargers may damage the battery and can cause fire. This battery charging voltage is 14.4V ~ 14.6V, maximum charging current is 10A.
Safety Guide
Do not disassemble the battery pack..
Do not puncture, drop, crush, throw, hit, open, or modify the battery.
Do not let water getting inside the battery.
Do not insert any foreign object into the Output and In port.
Do not expose the battery to heat above 60°C (140°F) or incinerate the battery.
Keep the battery away from children.
Always dispose of used batteries in accordance with local regulations.
If this battery is misused or abused, it can result in personal injury from heat, smoke, fire or explosion.
Obtain approval of airlines or courier companies before traveling with or shipping this battery pack.
Charging: Only use the chargers supplied with the battery or BiXPower authorized chargers to charge the battery. Chargers with incorrect voltage, current, or polarity settings may damage the battery. Please monitor the charging process and react to potential problems that may occur. If you cannot, please make sure to leave it on an isolated fireproof area, away from other flammable materials.
Storage & Handling: DO NOT leave a fully exhausted battery on a shelf. Charge it to least at 50% or more if you do not need to use it for a long time. Do not leave the battery dormant for long periods of time. We recommend using the battery at least once a month. If a battery has not been used for a long period of time, please perform the new battery exercise. Fully discharge and then fully charge the battery at least once every 3 months. Always store the battery in a cool and dry place between 0°C (32 F) and 20°C (70°F), and away from flammable materials.
Fire/Smoke Emission: Batteries contain flammable/combustible material that can be ignited, explode, release toxic materials, cause burns or give off gases when heated or in contact with sparks or flames. In the event of fire, vapor releases, and/or smoke emissions, evacuate the immediate area of all unnecessary personnel.
