Battery characteristics
This Gepida battery is a large-capacity, high performance lithium-ion (Li-ion) battery that outputs large current. More compact and lightweight
than the conventional nickel cadmium (Ni- d) and nickel-metal hydride (Ni-Mh) batteries as well as it can keep a large amount of electricity.
Moreover, conventional batteries suffered from the memory effect, that is a symptom wherein batteries that were charged repeatedly before
being entirely discharged each time had an apparently strong decrease in capacity over the time. In contrast, the Li-ion battery does not have
the memory effect, so you can charge it anytime at your convenience.
Battery does not operate well in extremely hot or cold environment. During charging cycles, the battery goes through a chemical reaction
which is greatly influenced by temperature.
A battery is subject to self-discharge even if it is not used. The loss suffered due to self-discharge can be recovered by charging the battery
before use.
Sometimes, the travel distance with a new battery might be shorter, but this will improve by using and charging it 2 to 3 times.
In a cold environment, below approximately 10 ° , the output capacity of the battery decreases, leading to a shorter travel distance or a
reduced power assist. Its capacity automatically recovers by the rising temperature. Even a high-performance Li-ion battery will suffer a gradual
decline in its capacity after repeated charge-and-discharge cycles (appr. 800 cycles), necessitating its replacement. This is the nature of the
battery and is not considered as a malfunction.

Battery characteristics
Avoid charging the battery at high temperatures, such as exposed to direct sunlight or near hot stove, or immediately after operating the
battery. These conditions can shorten the battery life or travel distance. If the temperature of the battery increases significantly as a result of
direct heating, it might become unusable.
The self-discharge rate is lower than that of the conventional batteries. Nonetheless, a battery that is completely discharged will suffer
accelerated deterioration. If you do not ride the Pedelec for a period of 3 months or more, remove the battery from the vehicle and place it
apart. Store it indoors, in cool (10-20 ° ), dry area.
The Li-ion battery does not operate well at high temperature.
Do not store the battery at high temperatures such as inside an automobile exposed to direct sunlight or near to any kind of heating device.
Do not charge a battery that is fully charged.
The necessity of replacing the battery depends on the usage of the pedelec, external temperature, and charging method. If the travel distance
per charge becomes considerably shorter than normal; it is time to replace the battery.

Battery characteristics
After 350 to 450 charging cycles the capacity of the battery decreases to approximately the half of the new battery. This average is calculated
on the basis of a usage at general road conditions, and an annual 200 charging cycles at 25 ° .
The necessity of replacing the battery depends on storage conditions, charging temperature, riding conditions, and external temperature. The
replacement interval might be shorter than the above stated if the battery is used under unfavourable conditions.
The Li-ion batteries are recyclable. When a used battery is due for replacement, you can have it recycled by the dealer. By taking this little
effort, you can contribute to a sustainable development of the planet.

Before charging the battery
Do not use the power cord if it is damaged.
Keep the charger away from pets and the reach of children in order to avoid injuries.
Never use the charger to charge other electrical appliances.
Do not handle the power plug for charger with wet hands nor touch the contacts of
charger.
Do not touch the charger or the battery for long time during charging.
The temperature of the charger might reach 40 ° to 60 ° during charging.
Be sure to use the original Pedelec charger, because other chargers a likely to cause
unrecoverable damage to the battery.

Before charging the battery
Place the charger on a flat and stable surface.
Avoid dropping the charger.
Do not place any objects on or cover the charger during charging.
Do not step on the charger.
Make sure the contact points of the charger and the battery are clean and dry.
Do not touch the contact points with metal object.

Charging
The optimum temperature for charging the battery is between 15 ° -25 ° . The internal temperature of the battery can be higher immediately
after a ride or if the battery is exposed to direct sunlight. This can result in the internal temperature of the battery exceeding the specified
starting charging temperature, which prevents it from being charged. To cool down the internal battery temperature, to a level that enables
the charger to start charging, can take up to approximately 3 hours when the room temperature is 30 ° .
. hoose a location that meets the following conditions for charging:
Flat and stable surface
Dry place
Well-ventillated and without excessive humidity
Out of reach of children or pets
Room temperature between 15 ° and 25 °
Even though charging might start normally, it will terminate automatically in case the temperature
falls below 20 ° , or rises above 30° .

Charging
There are two ways of charging:
1. onnecting the charger to the battery directly.
2. Leaving the battery in the console of the pedelec, and charging it
via the carrier console.
The remaining capacity of the battery pack can be checked any time
by pressing the button on the left side (as shown in the picture).
Each LED indicates about 20% of the overall capacity of the battery pack.
If the battery pack is on the charger, it indicates the charging process with the green
LEDs „running”. When the LEDs stop running, it means the process
has ended and the battery pack is fully charged.
Now you can unplug the charger.
The batteries are protected against overcharging.

eatures of the Control Unit
1. To turn the control unit on, press the lower-right button
and hold it for one second.
2. If the bicycle icon is flashing, that means the battery pack
is not fitted properly. This means you will not have the
assistance! In this case the remaining distance meter is
empty as well.
3. If the bike sign is permanently visible and you see a
remaining distance value, the assist system is ready for
operation. Now you can adjust the assistance level for your
convenience. Use the left (decrease) and right (increase) arrow
buttons. However you can also change the assist level
during riding.
4. Final step, you should check the light and set them
on\off\auto mode with the lower left button.
5. Now you are ready to go!

Gepida Automatic Reduction System
There are 10 different assist levels for you to be able to use the pedelec always at your convenience. If the battery charge status is less than
35% the Gepida Automatic Reduction System lowers the assistance ratio down to the optimum level ensuring maximum range with assistance.
When the system turns on, the change in the assist level becomes immediately visible on the display.

GPDS system
The assistance is switched on by the speed sensor soon after you start pedaling the bicycle. So when the pedelec starts moving, you will
instantly experience the assistance. The reason why the assistance does not start immediately when pressing the pedal is to avoid accident for
instance in case you just put your foot back on the pedal at the traffic light. That is why the system is set in a way that the speed senson must
capture a minimal speed to turn the assistance on. When the assistance is on, ride the bicycle just like a regular one . The power and the
duration of the assist force depends on two factors:
1. How strong you push the pedal.
This is captured by the special torque sensor, and is very important at accelerations, when usually a higher pedal force is needed, so the assist
force will be higher as well.
2 . Which assist level the pedelec is used on.
This factor is more important after the starting period, when you want to keep a desired speed during the ride. If you wish a higher travelling
speed, just raise the assistance level on the control unit . The torque sensor will still work at this part though, so if you press the pedal harder,
the assist force will raise allowing an easy acceleration.
Warning!
If the assistance level is set to maxim m or near, be ca tio s when accelerating! In this case, the assist force is really high that may „p ll” the bicycle
from nder yo , which may lead to accidents and/or inj ries.
