Why Choose LiFePO4 Battery?
Traditional electric golf trolley battery use Lead Acid battery, it’s heavy, recharge is slow, need to be replaced every 2 years, the performance is average, and it’s not as green as the golf field grass.
As a new battery technology, LiFePO4 has lighter wight, strong power, short recharge time and amazing cycle life, what’s more, it’s more economic in a long term evaluation.
When we test the cycle life of lithium iron phosphate battery pack and lead-acid battery, we can see:
Testing Condition:
LiFePO4 Battery Pack as following:
Temperature: 20℃-30℃
DOD(Dept of Discharge): 100%
Charging Current: 1C(3.2A CC/CV)
Discharge Current: 1C(3.2A CC)
Lead Acid Battery as following:
Temperature: 20℃-30℃
DOD(Dept of Discharge): 100%/50%/30%
Charging Current: 0.1C(2.45V/cell)
Discharge Current: 0.1C(700mA CC)
Testing Results:
LiFePO4 Battery Pack as following:
Cycle Life＞2500 cycles
Lead Acid Battery as following:
Cycle Life at different DOD
100% DOD: 200-300 cycles
50% DOD: 400-500 cycles
30% DOD: 1000-1200 cycles
When we test the discharge efficiency of lithium iron phosphate battery pack and lead-acid battery, we can see:
This is a discharge performance curve of a 12V 7Ah lead acid battery from a leading manufacturer at room temperature. By constant current, the battery fails to meet its rated capacity, even at 350mA (0.05C) discharge rate. When the battery is subjected to higher loads of 1400mA(0.2C) and 5000mA (0.7C) the voltage drops is more severe and the delivered.
By comparison, CTECHI LiFePO4 12V7.5AH is the same size as its lead acid equivalent but less than half the weight. This battery exhibits a consistently flat voltage profile throughout its discharge until energy is depleted. This superior performance is maintained even at higher discharge currents, and the discharge capacity keeps stable even the discharge rate changes.
From the results of these tests, No doubt lead acid is a great product, but let`s check out our new-born: LiFePO4 Battery Pack.
We are dedicated to developing this killer product, geared to challenge lead-acid battery by its cutting edge feature.
