Battery almost empty, recharge now
Battery empty, recharge immediately
The remaining battery capacity does not translate directly to remaining physical range of the power chair. The
remaining physical range depends on the ambient temperature, the capacity, age and state of the battery, the
driving style of the operator and the terrain that the power chair is being used in.

Battery warnings are shown at the centre of the screen, in the "Active Mode" area.

Meaning
Battery overcharged.
Slow down and turn on the lights (if
fitted).
Battery completely empty. System turns off.
Recharge.
5.1.3: Complete charge:
A complete charge is long (from 10 to 12 hours), but efficient.
An incomplete charge will also reduce the durability of your batteries by one charging cycle.
The battery will not have enough time to store the energy correctly.
It will not be able to reconstitute the missing energy. The autonomy will be reduced.
A series of incomplete charges will have an even more disastrous effect: with the different batteries charged
incompletely and to different levels.
They will be out of balance and the entire set will have its life time reduced.
Conclusion:
To maintain maximum autonomy and optimise the durability of your batteries, every charging cycle started
should be completed.
Repeated short or incomplete charging cycles gradually reduce your batteries
’ capacity.
5.1.4: Specificities of lithium batteries :
Lithium batteries have two specificities :
More of 2 000 cycles of charge.
La décharge n’est pas progressive comme avec des batteries traction traditionnelles mais linéaire
puis extrêmement rapide.
En pratique cela signifie que les diodes passeront du vert au rouge en quelques minutes et que la phase
intermédiaire « orange » ne durera que quelques minutes.
Afin de tomber en « panne sèche » il est donc indispensable de procéder à une charge complète avant toute
longue sortie.
5.1.5: Range of the wheelchair:
The autonomy of your wheelchair on flat ground is about 20 to 30 km at nominal operation.
This autonomy is subject to the influence of various factors.
In practice the road condition, inclinations, driving mode, use of lights, tire pressure, total transported weight,
outside temperature, etc. … are some of the elements to be considered.
The way the batteries are charged has a considerable influence on the energy consummation and thus affects
the rapidity of discharge.
Attention: at 10 km/h, a distance of 25 km is overcome in about two hours.
When driving outdoors it is recommended to assure that a sufficient amount of energy is available to return to
the point of departure.
