SERFAS E-BIKE OWNER’S MANUAL
How can I calculate the capacity of an e-bike battery?
E-bike battery capacity is measured in Watt-Hours, or Wh.
This is the size of the “fuel tank” on the e-bike. Like a car,
some motors guzzle fuel, others sip. To calculate capacity,
multiply the voltage (V) used on the bike by the Ampere-
Hour (Ah) rating.
For the Serfas Dash Plus 500W, for example, multiply 48V
by 11.6Ah = 556.8Wh. More Watt-Hours equals more range
for your e-bike.

Why does the remaining battery amount shown on the
LEDs on the battery not match the “Energy Bar” on the
display?
The LEDs on the battery itself shown the remaining
charge left in the battery, but this doesn’t account for how
you are using the bike. The Energy Bar function on the
display is designed to account for the charge on the battery
plus other factors, like speed, throttle usage, and riding
conditions like hills or wind. You’ll see it fall more quickly
under heavy usage, and more slowly when you are not
taxing the motor.
