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.
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 CO2 type fire extinguisher in case of fire.
Safety and protection
>Never try to open the battery or dismantle the battery. De 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 LiFePO4 chargers or standard chargers programmed to be used within the specifications of the batteries.
Guidance for connecting battery packs
>Use connection wires of sucient diameter. Take maximum current and length of the cable into account when
selecting the connection 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 they are connected.
>Up to 8 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.
Charging and discharging
>Check the mains on the right voltage at the moment you connect your battery charger.
>The battery should only been 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 should not be charged with damaged cables. Check before charging the batteries.
4

>Use the charger in a dry environment. The charger should be kept away from moisture unless the charger is a waterproof
one.
>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.
>The battery can’t be over-charged and is protected against over-discharging. The safety-electronics will disconnect the
load in case of over-charge or over-discharge.
>Prevent charge and discharge currents outside the specifications. Make sure you install enough battery capacity to
guarantee that currents stay within specification when maximum load is applied. The battery will disconnect in case
of over current but allows higher (peak) currents for a few seconds. Working outside the normal current range regularly
will shorten the life of the battery.
>The battery has a self-discharge rate of 3% per month when no equipment or monitoring instruments are connected.
Check the battery regularly on state of charge and charge in case the battery is below 50% SOC (State Of Charge) or
below 12,8V. Charging the batteries once a month will make sure that the State of Charge readings stay accurate since
the measurement is recalibrated automatically every time the battery is fully charged.
>In case the battery is not used for a longer period it is advised to disconnect all the equipment from the battery to
prevent discharge by e.g. monitoring instruments.
>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.
Warning when used in parallel or series
>Before batteries are connected in parallel they should be charged to the same State of Charge level (+/- 10%). This
to prevent high currents and sparks when they are connected in parallel. The voltage on the connections should not
exceed 0,1V dierence at the moment the connections are made.
>When connected in series the batteries should be fully charged separately before connecting them (only 12V batteries
and not more than 3 in series).
>When placed in series the battery pack can be charged by using a 12V charger (dedicated LiFePO4 charger 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.
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.

THE JAROCELLS APP
General
All the information available inside the battery, like State of Charge, current going in or out, voltage, temperature are
transmitted real time through the Bluetooth transmitter. The parameters can be made visible with the use of the
JAROCELLS App. Even the smallest JAROCELLS battery is equipped with this modern wireless monitoring system.
Download and Installing the App
>The App is available for Apple and Android smartphones.
>Download the JAROCELLS App from the Google Playstore of App store.
Android version 4.3 or higher is required.
Making a connection with your JAROCELLS BT
>Make sure you are close to the battery (max. 6m) and your Bluetooth is
switched on on your smartphone.
>When the App is activated it will search for JAROCELLS batteries automatically.
Found batteries will be listed on the screen.
>Double click on the battery you want to connect with. The App will make contact
now and the main screen will appear.
Available information in your App
>When the connection is established the main screen appears showing State
of Charge, voltage and general status of the battery.
>By swapping the main screen to the left, the next screen appears. This screen
shows information about in- or outgoing current, number of cycles, voltage
and temperature.
>By swapping the screen to the left another time the information screen is shown.
On this screen massages will be shown like end time of charging.
