Feature Of Lifepo4 Battery:
1. Superior Safety: Lithium Iron Phosphate chemistry eliminates the
risk of explosion or combustion due to high impact overcharging or
short circuit situation.
2. High power: Delivers twice power of lead acid battery, even high
discharge rate, while maintaining high energy capacity wider
temperature range: -20℃~60℃.
3. Long cycle life: offers up to 20 times longer cycle life and 5
times longer/calendar life the lead acid battery, helping to
minimize replacement cost and reduce total cost of ownership.
4. Lighter weight: About 40% of the weight of a comparable lead
acid battery. A “dron in”replacement for lead acid batteries.
5. Superior Safety: Lithium Iron Phosphate chemistry eliminates the
risk of explosion or combustion due to high impact, overcharging or
short circuit situation.
6. Increased Flexibility: Modular Design enables deployment of up
to up to ten battery in parallel.

The Advantages of Lithium Iron Phosphate Batteries
1. High Charging and Discharging Efficiency
Lifepo4 batteries are lithium-ion secondary batteries. A major use
is for power batteries. lifepo4 battery charge and discharge
efficiency is high, with charge and discharge efficiency reaching
over 90% in the discharged state.
2. LiFePO4 Battery Safety Performance is High
Lithium iron phosphate crystals in the PO bond is stable, not easy
to decompose, will not collapse or heat as lithium cobaltate, even
at high temperatures or overcharge will not form strong oxidizing
substances, good safety. It is reported that in actual operation, a
small number of samples were found to be burning in the pinprick or
short circuit test, but no explosion occurred. In the overcharge
experiment, a high voltage charge several times higher than the
nominal voltage was used and an explosion was still found.
Nevertheless, its overcharge safety has been greatly improved
compared with ordinary LiCoO2 battery with liquid electrolyte.
3. LiFePO4 Battery Has a Long Cycle Life-Lifepo4 battery is a lithium-ion battery with lithium iron
phosphate as the positive electrode material. Long-life lead-acid
batteries have a cycle life of about 300 times, up to 500 times.
Lithium iron phosphate power batteries have a cycle life of over
2000 cycles, with a standard charge (5 hour rate) of up to 2000
cycles. The same quality of lead-acid batteries is "new half year,
old half year, maintenance half year", up to 1 ~ 1.5 years, while
lifepo4 battery in the same conditions of use, the theoretical life
will reach 7 ~ 8 years. Considered together, the cost performance
is theoretically more than 4 times that of lead-acid batteries.
High current discharge can be charged and discharged quickly with
high current 2C. Under the special charger.
4. Good Temperature Resistance
The peak temperature of lithium iron phosphate can reach 350℃-500℃.
Wide operating temperature range (-20C - +75C), high temperature
resistance, lithium iron phosphate electrothermal peak temperature
can reach 350 ℃ -500 ℃.
5. LiFePO4 Battery High Capacity
It has a larger capacity than ordinary batteries. The single cell
capacity is 5AH-1000AH.
6. No Memory Effect
Rechargeable batteries work in the case of often not fully
discharged, the capacity will quickly drop below the rated
capacity. This phenomenon is called the memory effect,like NiMH,
NiCd battery, but lifepo4 batteries do not have this phenomenon, no
matter what state the battery is in, with the charge, no need to
charge and discharge.
