GENERAL INFORMATION ON Li-ION BATTERY
The Li.-ION BATTERY PACK consists of a group of elementary battery cells based on the Li-ION technology (Lithium
-ION) opportunely connected encased into a suitable shell, equipped with a specific plug for the connection to the
battery charger and one cable, ended by a red connector, designed to connect the battery pack to the motor
propulsive to the SUEX DPV.
To exploit the Li-ION technology provides the SUEX battery packs the utmost performance, the compactness,
reliability and user -friendly characteristics that makes them, at the present state of the art, the most advanced energy
source to feed the SUEX devices.
It is anyway important to know that the correct and safe interaction with the battery packs of the Li-ION kind
– in
particular to prolongate their high efficiency along the time
– is related to the understanding of some characteristics
that are intrinsic for the Li-ION technology and to the respect of basic good practice from the users.
Therefore the user must be aware of the following.
The Li-
ION cells, diversely for other kinds of batteries, does not show any significant “memory effect”, then IT IS NOT
NEEDED AND IT IS IN FACT ARMFUL TO DISCHARGE COMPLETELY before recharging.
Their DISCHARGE BELOW CERTAIN LEVELS determines the RAPID DETERIORATION OF THE BATTERY and
even ITS EARLY AND IRREVERSIBLE DAMAGE: it is therefore OPPORTUNITY AND RECOMMENDED to always
keep them at a high level of charge.
The correct recharging conditions (current and voltage) cells are of the utmost importance to ensure the best and
most prolonged battery efficiency: it is for this reason that RECHARGING MUST BE EXCLUSIVELY WITH THE
CHARGER SPECIFICALLY INDICATED.
The safe use of lithium-ion cells is made possible thanks to advanced internal electronic systems integrated on board
the battery packs (called BMS: Battery Management System) which have the function of preventing, controlling and
solving combinations of electrical and mechanical factors and environmental that - if they were not properly managed
- could cause the cells to overheat and fire. THE FUNCTIONING OF THESE ELECTRONIC SAFETY SYSTEMS
necessarily presents a (very low but never zero) ENERGY CONSUMPTION WHICH DRAWS FROM THE STORED
CHARGE in the battery: IF THE BATTERY PACK IS LEFT INACTIVE FOR LONG PERIODS OF TIME - months,
years - CONSUMPTION OF THE INTERNET CONSUMPTION (for the mechanism described in the previous point)
TO THE IRREVERSIBLE LOCK of a battery that is initially lightly charged.
For intrinsic reasons related to the chemistry they use, all batteries are subject to a natural progressive and slow
aging which determines - in the very long period - a reduction in the amount of charge to be stored at full charge.
Therefore batteries have a LONG BUT NOT INFINITE OPERATING LIFE. They last several years in efficiency if
they are used and recharged properly.
Finally, the user should be aware of the fact that THE TRANSPORT OF LI-ION TYPE BATTERY PACKS IS
SUBJECT TO STRICT RESTRICTIONS - IN PARTICULAR TO AIR TRANSPORT - AND TO SEVERE CONTROLS
ACCORDING TO THE INTERNATIONAL REGULATIONS in place and historically in rapid evolution . Therefore
special packaging practices and transport documentation are necessary for the handling of these items.
Therefore, the BATTERY is an element with a very high technological content thus it requires a conscious use by
those who use it: the few and simple precautions necessary to keep it performing and safe over time are widely
described in the remaining chapters of this manual.

BATTERY DESCRIPTION
The LI ION BATTERY cannot be opened, it is sealed by the manufacturer and cannot be dismantled in any part. It is
a unique piece and is a spare part in its entirety.
The Li-Ion BATTERY is made by several cells connected in series / parallel placed inside a special container, a buit
in BMS electronic device manages the cells both in balancing and in protection.
The BATTERY is marked with a serial number and with the certification code,
marked on the top cover of the battery (see Fig. under).
In case of need, the number shown must be mentioned for requests for assistance
or for the supply of spare parts.
