BATTERY
Your Grati uses the Eggrider V2 display which works in harmony
with your motor controller to read information from your batteries
to give you information about your remaining battery power. Battery
percentage is read by the system based on voltage (see previous
section). 58.8V will be 100% charge, 44V will be 0% 52.4V will be
50%.
It’s good to understand how your bike is calculating remaining bat-
tery level so that you can accurately judge how far you can keep trav-
leing. Your remaining battery percentage can be aected by hard ac-
celeration, big hills, top speed tests, etc. This riding uses large current
draws that can create momentary reductions in the voltage reading
that can make your remaining battery appear less than it is. A return
to normal riding will slowly return the remaining battery to the correct
reading soon after.
For dual battery bikes, the bike will draw from both batteries at the
same time. Both batteries will drain at a slightly dierent rate, but the
remaining battery level will be taken as an average of both batteries. If
you turn o one battery and leave the other on, the bike will only drain
from the battery that’s on. You can choose to ride with both batteries
on or switch them on and o as you like.
Battery level can be seen on both the top of the display and the
Eggrider app when connected and in use (only when the bike is pow-
ered on and connected to the app)
READING BATTERY LEVEL CHARGING YOUR BATTERY
Ensure the battery is fully charged before your first ride. To connect
your charger to your battery, locate the charge port on the side of the
battery under the protective rubber plug. First, plug the charger into
the battery and then into your wall outlet. The charger will show a red
light indicating that the battery is charging. Once fully charged the
light indicator will turn green.
Remove the charger from the battery within one hour after it has
been completely charged. The charger will automatically stop
charging when the battery is full, however, unnecessary wear to the
charging components can occur if the charger is left attached to the
battery and power source for too long. The battery can be charged
after each use. Charging the battery after short rides will not cause
damage.
TIPS:
• Do not charge the battery in a wet/humidplace or anywhere ex-
posed to strong sunlight.
• Always charge your battery where temperatures are between 5
- 25 °C. Charging outside these temperatures can damage your
battery.
• Charge the battery with the supplied charger. Do not attempt
to use another charger as it may damage the battery or cause a
• fire or an explosion.
• Do not leave the battery unattended while charging.
• The battery can be charged on or off the bike. To remove the
battery, turn the key to the off and unlocked position.
