5. 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 ARMFULL 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.
6. BATTERY DESCRIPTION

8. KNOW THE BATTERY CHARGE STATUS
8.1. CHARGE INDICATOR ON BOARD THE SCOOTER
On the right side of the Scooter there are two led: one blue and one red.
The BLUE LED lights on when the Scooter switch ins in ON position –both in LOW and HI speed.
The RED LED lights on when the battery is discharged and the residual autonomy is of few minutes : about 15
minutes in LOW speed and 10 mins in HI speed with a brand new battery pack.
Note the following:
•The charge indicator on the Scooter (or its display on an external device) provides an approximate indication of
the BATTERY charge status. Depending on the general condition of the BATTERIA and its use, the various
elements that indicate the state of charge during use may not accurately reflect the residual state of charge of
the BATTERY.
•The indication of the state of charge is a relative indication, that is referring to the actual condition of the
BATTERY and not to that of a new battery (at maximum efficiency).
•The BATTERY is subject to a natural decrease in its capacity over time due to various factors including the
main ones being age, how to use it and environmental conditions.
•Particularly heavy use or, on the other hand, too mild (with a few complete charge / discharge cycles),
particular environmental factors and battery damage can lead to:
•- early decay of its effective capacity
•- the reduction of its delivery duration for use
•- falsified readings of the state of charge.
•The same BATTERY in different environmental situations could therefore show different delivery durations.
•It is therefore important to charge the BATTERY 100% before each dive, that is, charge it, until the charger
marks the end of the charge.
•Do not use the charge indicator as a tool to program the dive or the duration of the dive during its course, but
program the dive with the usual safety parameters.
NOTE: SUEX s.r.l. declines any responsibility for the failure or incorrect evaluation of the residual battery
charge that has led to incorrect assessments regarding the autonomy of the Scooter.
8.2. BATTERY STATUS THROUGH BLUETOOTH CHANNEL
SUEX DPVs are equipped with bluetooth devices that allow to get motor and LI ION battery information.
These functions are available only out of water and require the Calypso App (available on Google Play & App
store).
In order to turn the Bluetooth system on, the battery has to be connected to the motor and the Scooter has to be
switched ON.
In order to read the battery data when the battery is off-board, connect the battery to the charger and plug the
charger to the main. Once the Bluetooth devices are ON, the application is ready and the data can be read.
First time connection will require Bluetooth pairing of devices and smartphone.

9. BATTERY CHARGE
9.1. HOW TO CHARGE THE BATTERY
To charge, place the BATTERY in a safe place away from people and flammable objects and proceed as described
below.
USE ONLY THE APPROPRIATE BATTERY CHARGER
The battery should ONLY be recharged using the specific battery charger supplied (code 71101).
When the charger is not in use, disconnect it from the wall outlet and put it in its case.
CHARGE PROCEDURE
CAREFULLY READ THE BATTERY CHARGER INSTRUCTIONS MANUAL.
Charge the battery before each use, allowing it to cool before inserting it into the Scooter; during this phase the
battery could release hydrogen which would inevitably accumulate inside the airtight scooter.
The accumulation of hydrogen (in special conditions) could cause accidents, with injuries to people and things.
Extreme temperatures can affect the battery's charging capacity.
Leaving the battery in hot or cold climates, such as a closed car in mid-summer or mid-winter, reduces battery
capacity and life. Always try to keep the batteries between 15 ° C (59 ° F) and 25 ° C (77 ° F). Battery performance
is significantly reduced in temperatures below 0 ° C (32 ° F).
Charging must take place in an appropriate place: covered and ventilated, away from flammable objects or liquids,
away from crowded rooms:
1. Remove the battery from the Scooter. When the battery is removed, disconnect the red connector;
2. The battery must be connected to the charger by means of the appropriate connector (26).
THE BATTERY SHOULD BE CHARGED ONLY THROUGH THE CONNECTOR (26),
IT IS FORBIDDEN TO USE THE CONNECTION (RED) CONNECTOR TO THE
MOTOR: DANGER OF FIRE, EXPLOSION, SERIOUS DAMAGE OR DEATH.
Unscrew the plug of the charging connector (24) (fig.1);
Connect the charging connector (26) to the charger (see charger instructions);
Connect the power supply socket of the battery charger to the mains;
Do not connect any other device to the battery while charging;
During charging, the battery should be kept outside the Scooter (the battery must, in fact, be inserted and
connected to the motor only immediately before use and removed from the Scooter immediately after use);
If, however, the battery should be recharged from inside the Scooter it must first be disconnected from the motor
(by disconnecting the red connector) and it must be taken into account that the charging phase naturally
determines a certain development of heat: it must be taken care of perform the operation to make sure that the
temperature and ventilation conditions are such as to effectively dispose of the heat produced and avoid the
abnormal overheating of the battery;
Once charging is complete, disconnect (in order) the charger from its main power source and battery;
Once charging is complete, NEVER leave the charger connected to the BATTERY;;
After charging, allow the battery to cool down before inserting it into the Scooter.
CHARGING FROM OUTSIDE
To charge the battery from the outside:
•remove the cap (6A - Fig.1);
•connect the charging cable (supplied with the LI ION battery charger) to the charging connector;
•connect the charger power socket to the mains;
•connect the connector to the charging cable of the charger.
NEVER stop charging the battery: partial charges damage the battery and reduce
the autonomy of the battery itself!

IMPORTANT SAFETY WARNINGS DURING THE CHARGING PHASE
DO NOT attempt to CHARGE the BATTERY USING THE RED CONNECTOR
located on the bottom of the battery.
DO NOT attempt to CHARGE batteries that are DAMAGED or leaking, or that are
RUSTY.
ENVIRONMENTAL CONDITIONS IDEAL FOR CHARGING
The charging temperature range is 0 ° C + 36 ° C. The ideal battery temperature at the start of the charging phase
is 20 ° C.
9.2. WHEN CHARGE THE BATTERY
Fully recharge the BATTERY:
•BEFORE EACH USE taking care to let the BATTERY cool before inserting it into the Scooter;
•At least once every 2 months;
•When the RED LED lights up (the charge level is less than 20%).
9.3. NEW BATTERY, FIRST USE
A new battery operates at full capacity only after a few complete charging cycles (4-5): this for reasons related to
the activation of internal chemistry.
10. IMPORTANT WARNINGS ON THE BATTERY LIFE
BATTERY life (i.e. the total amount of energy that it can supply to the user device after a full charge) is a feature
that depends on numerous factors including environmental conditions, how it is used, how to charge and
discharge.
To counteract the natural progressive - normally very slow - decay over time of the battery life, the user must keep
in mind that:
•Extreme temperatures can affect battery capacity and charging efficiency.
•Batteries must be stored at a temperature between 15 ° C and 36 ° C (the ideal temperature is around 20 ° C):
conditions other than those described above can affect the effectiveness of the recharge as well as the number
of possible recharges.
•Leaving (and storing) the BATTERY in a hot (> 36 ° C) or cold (<15 ° C) environment reduces the battery
capacity and its life span.
•If during the use of the Scooter you notice a significant drop in distributed power, immediately stop use and turn
it off using the switch.
The state of efficiency of the BATTERY, as regards the duration of delivery, must be periodically checked: batteries
that show a 20% reduction compared to the condition at the beginning of their life must be replaced and disposed
of in the manner provided (see Cap. "Disposal").
WARNING!
At the end of the charge and before each dive, make sure that the cap (6A - Fig.1)
is closed correctly (HAND TIGHTEN WITHOUT FORCE).
Before screwing the cap (6A), check that the O-Ring and its seat are clean and
adequately lubricated with petroleum jelly.
IMPORTANT NOTE!
Excessive discharge can irreparably damage the battery.

Rev.01 –21/12/2020
Pag. 10/19

An indication of the current state of efficiency of the battery is the "burn-test" test (see User manual Burn - test).
11. IDEAL CONDITIONS FOR BATTERY OPERATION AND DISCHARGE
It is recommended to use the BATTERY at a temperature between 15 ° C and 36 ° C.
To avoid rapid deterioration, the BATTERY must NEVER be completely discharged under any circumstances: the
cut-off device is present in to the BATTERY (see chapter "In the event of cut-off intervention").
12. ELECTRONIC BATTERY CONTROL SYSTEMS (BMS) AND THEIR EFFECTS (CUT-OFF)
LI ION BATTERY PACK integrates the following electronic devices / systems with the function of managing the
safety of the cells that make up the BATTERY.
•Emergency thermostat: intervenes during the charging phase in the event of a BATTERY charger failure which
could lead to battery overcharging. It prevents the BATTERY from overheating by cutting off the charging
current.
•Cut - off: intervenes in case of attempt to overdischarge. It eliminates the electrical absorption by interrupting
the supply of current to the user device, it is restored by recharging the BATTERY.
•Overcharge protection: during the charging phase it prevents the circumstance that the charger does not
automatically interrupt the charging period.
•Short circuit protection: each cell inside the battery pack is individually protected electronically against
accidental short circuits, in any case DO NOT SHORT CIRCUIT THE BATTERY BECAUSE IT COULD
DAMAGE THIS SYSTEM IRREPARABLY and the BATTERY should be replaced.
•Auto OFF system: the battery is equipped with a protection system against accidental discharges. It provides
for the interruption of the voltage in case the scooter is left on for more than 4 hours without using it. To restore
operation, simply turn off the scooter by turning the switch to the OFF position, wait at least 5 seconds before
turning on again.
Particular attention must be paid to the presence of the cut-off system as its intervention determines the supply of
energy to the Scooter and this occurs suddenly.
The non-operating condition imposed by the cut-off system is temporary and normal operation is restored after
having recharged the BATTERY using the special charger. The cut-of intervention is to be considered the
electronic BATTERY protection system against accidental total discharge, it is located inside the BATTERY and is
connected in series between the BATTERY and the Scooter motor.
The function is to prevent the excessive discharge of the cells with the possible danger of reversing the polarity of
one or more cells, with consequent possible destruction of the BATTERY pack with the potential to create even
very serious damage to things and / or people.
During the discharge of the batteries, the voltage drops until it reaches a limit value at which point the cut-off
prevents, by interrupting the power supply, the BATTERY can be discharged further.
When the cut-off intervenes, the battery no longer supplies voltage to the connector.
To restore the situation of use of the battery, it is necessary to recharge it only by means of the special battery
charger (see user manual of the battery charger) and restore the circuit.
The cut off intervention is to be considered exceptional and this event should not occur during normal use of the
battery, as the correct use of the vehicle does not require excessive discharge of the same.
12.1. IN THE EVENT OF CUT-OFF INTERVENTION
In case of intervention of the cut-off system, proceed as follows:
•Follow the procedure for opening the scooter;
•Disconnect the battery motor power connector;
•Remove the battery from the Scooter;
•Leave the battery to rest for at least 2 hours: this is the minimum time necessary, in this case, to allow the
battery to cool down and return to the waiting state for charging;
•Connect the battery charging connector to the battery charger;
•Proceed with charging, following the instructions in the battery charger user manual.
IMPORTANT NOTE!
After using the Scooter, always cut off the power supply to the motor by using
the Scooter main switch: the electronic control of theScooter motor board, even
with the engine not running, has a very low energy consumption which, in the
long term, can lead to complete discharge of the BATTERY, with possible
irreversible damage of the BATTERY PACK.
