Product Description

Product advantages

 

The charge and discharge efficiency of lithium iron batteries is more than 2 times higher than that of general-purpose batteries. When the start-stop system is frequently started, the rapid charge and discharge characteristics of lithium iron batteries can make the starting system more stable and the battery life longer.
 

 

The fast and stable power supply characteristics of iron lithium batteries can improve the combustion effect in the cylinder, make combustion safer, and achieve the effect of improving starting power. Simply replacing the battery can easily increase the power of the car.

Product Description

 

Using LiFepo4 battery, it has super power and longer life.

High efficiency output: standard discharge is 2~5C, continuous high current discharge can reach 10C, instantaneous discharge (10S) can reach 20C
 

 

The performance is good at high temperatures. When the external temperature is as high as 65°C, the internal temperature is as high as 95°C. When the battery is discharged, the temperature can reach 160°C. The battery structure is safe and intact.
 

 Even if the inside or outside of the battery is damaged, the battery will not burn or explode, and is extremely safe.


Excellent cycle life, after 500 charge and discharge cycle tests, the battery discharge capacity is greater than 95%
 

 

features and benefits

increase motivation,
The fast and stable power supply characteristics of lithium iron phosphate batteries can improve the combustion efficiency of the car's missing cylinder, making it safer to burn, and achieving the effect of improving performance.

Reduce fuel consumption,
Due to its fast charging and discharging characteristics, lithium iron phosphate batteries can minimize the loss of the car's generator and compressor and reduce fuel consumption by more than 10%.


Extra long life,
The lithium iron phosphate battery itself can be deeply charged and discharged for more than 2,000 times, giving it a lifespan of 5 to 10 years
 

 Light weight,
The lithium iron phosphate battery weighs only 1/2 to 1/3 of the original tram in the same size, effectively reducing the weight of the vehicle.

emergency start function,
If the car is left idle for a long time, or you forget to turn off the headlights, you no longer have to worry about running out of power. You can start the car with just one click.

Voltage display function,
The health status of the tram can be detected at any time to ensure that the vehicle's performance remains at its peak.
