What is the expected lifespan of the battery?

Under normal usage conditions, our battery maintains optimal performance for approximately 800-1000 charge cycles, equivalent to 3-5 years of usage, depending on riding habits and maintenance.

 

How long will a 48V 20Ah battery last on an ebike?

The battery life depends on various factors, including motor power, riding conditions, terrain, rider weight, and assist level. On average, a 48V 20Ah battery provides approximately 40-70 miles (65-110 km) per charge when used with a 500W-750W motor under moderate riding conditions. Higher power motors or aggressive riding styles may reduce the range, while efficient riding on flat terrain can extend it.

 

How many batteries does it take to make a 48V 20Ah battery?

48V 20Ah batteries are usually composed of 21700 or 18650 lithium-ion batteries, at GEB, we first use high-quality 18650 lithium batteries (3.6V, 2500mAh each battery), usually the battery needs 13 series, 8 parallel (13S8P) configuration, a total of 104 batteries. If 21700 batteries (3.6V, 5000mAh each) are used, a 13S4P configuration of 52 batteries is sufficient. The exact amount may vary depending on the battery brand, capacity, and manufacturer design.
