Home > About LifePo4

Specification:

1.Standard Voltage; 3.3V

2.OverVoltage: 3.9V

3.Best charging current: 0.1--0.2C

4.Most charging Rate: 1.0C ( may reduce 10% cycle life)

5.Most discharging Rate: 10C(special designed product)

6.Most discharging rate: Can be fully discharged (The voltage of single battery 1.8V, remanent rate nearly approach Zero)

6.Cycle Life: at least 1000-3000 cycle times

Characteristics:

1. Fast charging: Can be 90% fully charged in 60 minuates(1.0C).

2. For all high discharge/ power output applications : Quite safe and can high discharge(5C~10C),more than 5 times discharge of the rechargeable battery used at present.

3. No memory effect :no matter how much the electric quantity is , can be recharged at any time, no reduction of the capacity.

4. Large capacity: can be fully discharged, lead-acid battery can only be 70% discharged, over discharge may destroy the battery.

5. Extra long cycle life : Even high C-Rate discharge can have more than 1000 cycles( 5-10 years cycle life), For Normal C-Rate discharge,can have Up to 3000 cycles in theory.

6. Quite safe: The positive pole of LiFePO4 is non-flammable and stable in high temperature,So quite safe when high discharge. Little discharge heat so no explosion.( No temperature controller needed)

7. High Volt and stable: Better than Lead-acid , Ni-MH and Ni-Cd battery, Lead- acid 2V/cell; Ni-Mh/Ni-Cd: 1.2V/cell, operating voltage of li-ion3.3V/cell,moreover, can be stable voltage within 85% discharge.

8. Small in size and light in weight : campare with other moto battery , 1/2 size of Lead-acid battery , 70% size of Ni-Mh/Ni-Cd battery, 1/2 weight of Lead-acid battery, 70% weight of Ni-Mh/Ni-Cd battery.

9. RoHS approved : No pollution during production, 100% green product, absolutely environment protection.

10. High energy efficiency: energy efficiency up to 95%.

11. Broad operation temperature: -20~75 Centigrade.

COMPARISON DATA AMONG VARIOUS LITHIUM BASE BATTERIES

	LiFePO4	LiCoO2	LiMn2O4	Li(NiCo)O2
Safety	Excellent Safest and most envirofriendly among all the listed groups	Very unstable, must handle with extremely care, it might explode or catch fire under collision, over-charged, short circuit or when heat build-up.	Have to handle with care, or it might explode or catch fire under collision or over-charged.	Very unstable, must handle with extremely care, it might explode or catch fire under collision, over-charged, short circuit or when heat build-up.
CYCLE LIFE	ExcellentCycle life can be as long as over 5,000 cycle, best among all the listed groups.	AcceptableCycle life only up to 300~500 cycle. Not good for high C-rate discharge.	UnacceptableCycle life only up to100~800 cycle, depending on the discharge C-rate.	AcceptableCycle life can be 300~500 cycle. Not good for high C-rate discharge.
POWER WEIGHT DENSITY	Acceptable	Good	Acceptable	Good
LONG TERM COST	Excellent Most economic	High	Acceptable	High
Temperature Range	Excellent (can be discharged at -45~ 70 Centigrade)	Decayed beyond 55 ~ -20 Centigrade	Decayed extremely fast over 50 Centigrade	Decayed extremely fast over 55~ -20 Centigrade

REMARKS

1. Although, Lead Acid battery is lower in cost and safety acceptable; however, with extremely toxic, worse for the environmental concern, short cycle life, heavy in weight, therefore, we don't put it as a group for comparison.

2. Nickel Hydride battery has a characteristic of low Power Weight Density, decayed faster under the high temperature, worse in memory effect, not suitable for high output usage.

3. The Lithium Iron Phosphate Battery has been proven as the most environmental friendly battery. It is the safest and most suitable for high output usage. It is also the best for storage battery usage. It is not necessary to use the equalizer and the protecting PC Board module.

The LiFePO4 battery Does not have the security hidden danger!!!!
