Longer Life---The LiFePo4 battery boasts greater stability when compared to other battery types, depending on its unique physical structure. Furthermore, its cycle life outperforms lead-acid batteries by an impressive 5 times.
Long Mileage---48V 30Ah batteries are a perfect fit for motors with 300-800W power. These batteries are capable of traveling up to 50km, but factors such as load bearing, road condition, and speed can affect their performance. With a max constant discharge current of 28A, these batteries ensure a reliable and efficient power supply for your motor.
No Memory Effect---The battery does not require a full charge for each charge, and a partial charge does not have any impact on the battery's cycle life or longevity.
More Safe & High Quality---This lithium-ion battery is equipped with a BMS protective board, which prevents overcharging, over-discharging, over-current and short circuit, while ensuring a long life expectancy.
Scope of Application---This battery pack series is widely utilized in various electric vehicles such as electric bicycles, scooters, motorcycles, tricycles, electric wheelchairs, and more. The 48V/60V electric bike battery is designed to be installed in any position, providing excellent resistance to shock and vibration.
