This 48V 20Ah LiFePO4 E-Bike battery is optimal for both Electric Motorcycles and Electric Bikes due to its Lithium Iron Phosphate composition and integrated Charge Protection with BMS. The BMS feature ensures the battery is safeguarded against overcharge and low discharge. In comparison to traditional lead-acid batteries, this lightweight battery provides ample power to your motor.
The battery is equipped with anti-vibration, flame retardant, and high-insulating materials that are environmentally friendly, ensuring maximum safety. Sunpack has developed a state-of-the-art packing process using high-quality LiFePO4 cells and an exceptional BMS. Our strict picking and matching process ensures consistent cell performance and adequate storage. The battery is required to undergo cycle testing to verify its qualification and durability.
Features:
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.
