SAFETY GUIDLINES
General safety
Attention should be paid to all safety instructions in this manual. Keep the manual located close to the battery for
future reference. Maintenance or repair work should only be carried out by qualified personnel. A damaged or abnormal
functioning battery should not be used. Keep the battery away from children. The battery should be used for general
purpose, small drive trains and source for static electrical equipment. The batteries should not be used for critical
equipment like medical equipment unless a thorough risk analysis has been conducted. Furthermore, the battery can be
used for light drive systems as well as for power supply of static equipment.
Explosion and fire
>The battery terminals have a dierent polarity. For this reason, you should not place any conductive materials on the
battery. When working close to the battery it is advised not to ware any jewelry or watches to prevent short circuits.
>The battery should not come in contact with fire or be placed close to a heat source.
>Use and store the battery on a non-flammable, heat resistance and non-conductive surface.
>Contact with very humid air and water should be avoided as much as possible. Store the battery on a dry and safe place.
>Use a type D, foam or CO2type fire extinguisher in case of fire.
Safety and protection
>Never try to open the battery or dismantle the battery. The battery contains electrolyte. Under normal operational
conditions contact with the electrolyte is impossible. If the battery casing is damaged do not touch the electrolyte or
other materials released from the battery. In case of contact with the electrolyte: rinse thoroughly with water and consult
a doctor.
>Prevent damaging of the battery. A damaged battery should not be used anymore.
>A damaged battery has to be disposed according local guidelines as small chemical waste.
>Prevent mechanical shock and extreme vibrations as the batteries can get damaged. Never cut or drill in the casing.
>Prevent contact with the connections of the battery.
>Use only special LiFePO4chargers or standard chargers programmed to be used within the specifications of the batteries.
Instructions for connecting battery packs
>Use cables of sucient thickness. Pay attention to the required current load and length of the cables.
>Putting batteries in series is only allowed for 12V batteries and up to a maximum of three of the same type (36V). Make
sure that the batteries are fully charged separately, before connecting them in series.
>Up to eight batteries can be placed in parallel to increase the capacity. For safety reasons however it’s recommended
to limit the current to two times the maximum current of one battery or to fuse every battery separately by a fuse of
two times the maximum continuous current of one battery. This is to avoid large current spikes across one battery as
the other batteries would fail.
Charging and discharging
>Check the mains on the right voltage before connecting your battery charger to the mains.
>The battery may only be charged with the cables supplied with the battery charger. Extending the charger cables can
cause slow or not completely charging of your battery.
>The battery may only be placed in a dry environment, in a non-flammable environment and on a non-conductive
surface be charged.
4

>Only a charger suitable for LiFePO4may be used to charge the battery.
>The battery must not be charged with damaged cables. Check this before charging the batteries.
>Use the charger in a dry environment. The charger should not come into contact with moisture unless it is a waterproof
charger.
>Rapid temperature changes can lead to condensation. If this happens, wait until the charger is dry and has assumed
the correct temperature of its environment.
>A JARO BT battery cannot be overcharged, is protected against over-discharging and will not be damaged when
completely discharged.
>When discharging, ensure that the maximum current remains within specifications. It is important that sucient
battery capacity installed to prevent operating outside specifications at maximum consumption. Although the battery
switches o at high current, this only happens after a certain time to be able to absorb peak currents. Working outside
the normal current range regularly will shorten the life of the battery.
>The battery has a self-discharge of 3 to 5% per month. This is of course faster with connected equipment.
Check the battery regularly for State of Charge (SOC) and charge it if the battery is less than 50% SOC or less than
12.8V (12V batteries) or 25,6V (24V batteries) or 38,4V (36V batteries).
>In case the battery is not used for a longer period of time it is recommended to disconnect all the equipment from the
battery to prevent discharge by e.g. monitoring instruments.
>The battery should not be charged when the temperature of the battery is below 0°C. Discharging the battery up to
-20°C is allowed. Since the battery temperature will increase during discharge, charging can be done directly after
discharge when the temperature is over 0°C.
>A fully discharged battery should be recharged within 24 hours. The loads will be disconnected automatically when the
battery is fully discharged but the remaining energy is minimal. Self-discharge can lead to damage of the battery when
the battery is left in fully discharged state for a longer period.
>Even if the battery is not completely discharged, it is recommended to fully charge the battery at least once a month
to recalibrate the internal measurements to ensure that the reading remains reliable.
Warning when used in parallel or series
>When used in parallel or series, the batteries must be in the same State of Charge (SOC). Charge the batteries
completely separately and then connect them in parallel or in series.
>When connected in series the batteries should be fully charged separately before connecting them (only 12V batteries
and not more than three in series).
>When placed in series the battery pack can be charged by using a 12V charger (dedicated LiFePO4charger or charged
programmed to the charging specifications) for each battery.
>Charging batteries connected in series with a 12V charger on each battery is allowed when the minus of the chargers
are not connected with each other directly or through ground. Consult an electrician or your supplier in case of doubt.
>No more than three 12V batteries may be connected in series. With 24V batteries the maximum is two in series (48V);
provided they are charged separately by 24V chargers. The 36V batteries may not be connected in series.
Warnings for transportation
>Transportation of the batteries should be done packed in the original packaging or a packaging suitable to protect the
battery against shock of falling on the ground.
>Make sure the batteries are fixed properly during transport to prevent shifting of the load.
>Avoid mechanical shocks such as knocks and falls.

MANUAL LITHIUM ION BATTERY JARO-BT SERIE

THE JAROCELLS APP
General
All information that is available within the battery about the degree of charge, power consumption, voltage, temperature,
etcetera is made available via a wireless bluetooth connection to be read via our JAROCELLS App on an Android or
Apple device.
To download and install
>The App is available for Android (from version 4.3) and
Apple (from iOS version 7.2) devices.
>Download and install the JAROCELLS App from the Google Playstore

The names of the found batteries will be listed on the screen.
>Click on the battery you want to connect to. You will see the message “Connecting”.
>The App connects to the chosen battery and will display the data from this battery.
Available information
>When you have established a connection with your battery, the basic information
appears the screen. In the center you see the degree of charge of the battery (the
percentage, also known as the State of Charge) and below the voltage,
the capacity of the battery and the status. At “Estimated duration” you can see
the time it takes for the loading to complete, if the battery is being charged or the
time remaining until the battery is empty when it becomes empty and the load
does not change.
>If you swipe left (swiping motion) the following screen appears with actual
information: the voltage, the current (when charging / discharging), the temperature
of the battery and the number of charging cycles. The latter is the number of times
the battery is complete discharged and recharged (for the full capacity).
>After swiping left again, the System info screen will appear. This screen shows
notifications of possible particularities.
Change the name of the battery
>Give each battery a unique name.
>Connect your device to the battery and click on the three dots next to each other
in the upper right corner. Then tap the field with the current name.
>Enter the password 5678 and confirm with “Confirm”.
