Discharge performance in normal temperature

 

Discharge capacity /standard capacity×100%

(A)0.2C5A 100%

(B) 1C5A 98%

(C)5C5A 90%

 

Charge with 0.2 C5A standard charge in the condition of temperature 25°C±5°C,relative humidity 45%~80%(if there is especial statement,the charging way is same as this), rest for 10min,separated discharge with 0.2C5A,1C5A,5C5Ato cut-off voltage 30V,cycles for three times,One cycle capacity arrive standard, that’s to say it is qualified.(The below as the same)

2

Charging keep ability in normal temperature

Rest capacity standard capacity *85%

Recover capacity standard capacity*90%

Voltage reducing rate≤3%

Impedance increasing rate ≤10%

After standard charged,rest for 28 days,discharge with 0.2C5A to 30V,test the rest capacity; 0.2C/0.2C test the recover capacity, cycle for 3 times ,One cycle capacity arrive standard, that’s to say it is qualified.

3

Charging keep ability in high temperature

Rest capacity original capacity *80%

Recover capacity original capacity*90%

Voltage reducing rate≤5%

Impedance increasing rate≤20%

After standard charged,rest it in the constant temperature and humidity case of 60±2°Cfor 7days,Then take it out in room temperature for 2hrs,and discharge with 0.2C5 to 30V,test the rest capacity;0.2C/0.2C test the recover capacity.

4

Cycle life

Capacity Standard capacity *85%

After 1C standard charged ,discharge with 1C5A to 30V for10min,cycles for 2000 times.

5

Storage performance

0.2C5A discharging time

Store 3 months ≥4.5h;

Store 6 months≥4.25h;

Store 12 month≥4h.

After charge to 54.8±0.02V,separated store the battery for 3 months,6 months,12months,discharge with 0.2C5A to 37.5V and record the discharge time. The cycle for 3 times with 0.2C/0.2C and record the discharge time

 

 

 Remarks:

(1)    Standard charge:with the ambient temperature 20°C±5°C,charge with 0.2C5A,When the voltage is up to the limited charging voltage 54.80V,change to constant voltage charge, stop charging until the charging current is≤ 0.01C5A.

(2)    The Original situation:the original appearance, open voltage, impedance

(3)    The last situation:the last appearance, open voltage, impedance

(4)    Rest capacity:The first discharge capacity after the specific inspecting process.

(5)    Recover capacity:The discharge capacity that through time after time cycles after the specific inspecting process.

(6)    Charge with 0.2C5A,When the voltage is up to the limited charging voltage 43.80V,change to constant voltage charge, stop charging until the charging current is≤ 0.01C5A,Finish to charge,rest for10mins,discharge with 0.2C5A(1C5A,5C5A)constantly to cut-off voltage 34.5V.

 

 

 48v 15ah battery for e bike , e motorcycle ,e scooter  ,e tricycle ,e quadricycle . etc .

 

 

 

 

 

 

Feature

 

1)Long cycle life (2000 cycles) is several times greater than Ni-MH, Ni-Cd or SLA.

 
2) Non-Toxic, environmentally-friendly product.
 
3) High safety
LiFePO4 is an intrinsically safer cathode material than Lithium-ion since exothermic reactions can not occur in batteries based on this material
LiFePO4 cells do not incinerate or explode under extreme conditions
 
4) Good performance in high-current discharge cycles.
 

 

Aplification

used for e-bike,e-motor,electrical equipment ,electrical tool,EV-car,e-scooter
