Lifos 105 quick user guide
This guide should be read in conjunction with the main instructions included overleaf,
but the following points will enable speedy deployment of your Lifos 105 battery.
1. Your Lifos 105 is supplied partially charged. Please use this charge before connection to
a charger.
2. Lifos 105 can be charged by a solar panel (via a suitable charge controller) and any lead acid or
lithium phosphate battery charger. However, certain chargers are unable to charge Lifos 105 to
100%. In this case go to www.lifos.co.uk to see a large list of chargers that are approved or to
purchase the ocial Lifos Battery Charger.
3. The Battery Management System (BMS) within each Lifos 105 battery may give inaccurate data via
the Bluetooth App until ten charge and discharge cycles have taken place. This is because during
these ten cycles the BMS is balancing and calibrating the four lithium cells within Lifos 105.
4. If more than one Lifos 105 has been purchased and you wish to connect them in series,
parallel or both please see page 1 of this manual for detailed instructions.
If you have any questions regarding the use or operation of your Lifos 105 battery please contact the
Lifos help line on 01684 774000 or see the FAQs on www.lifos.co.uk

Lithium Iron Phosphate Battery
(LiFePO4)
Thank you for purchasing this advanced lithium iron
phosphate (LiFePO4) battery. Combining the very best
lithium cells along with an outstanding battery management
system ensures this battery will provide you with incredibly
long-lasting power in a super lightweight package.
A few tips on how to get the best from your Lifos 105 battery:
•Protect the battery from direct sunlight although it will work well in
a wide temperature range (-20 to +60 degrees C).
•Avoid using Lifos 105 in damp or wet conditions but if you do need to
use it in these conditions consider using an all-weather enclosure such as the
BB0001 Battery Box.
•Observe the correct polarity otherwise permanent damage could be caused
– the battery casing is marked with + and –.
•Don’t short circuit Lifos 105 otherwise permanent damage could be caused.
•Lifos 105 can be connected in Parallel (Fig.1). You are able to connect
up to 4 Lifos 105 batteries in parallel giving you a battery bank capacity
of 420Ah (105A x 4).
•Lifos 105 can be connected in Series (Fig.2). You are able to connect up
to 4 Lifos 105 batteries in series giving you a battery bank voltages of
12v (single battery), 24v (2 x batteries) 36v (3 x batteries) or 48v (4 x batteries).
The Lifos 105 can be connected up in parallel or series when needed but
only in the below congurations:
Please note when connecting up multiple batteries you must rst fully
charge each battery and check they don’t have a dierence of more than
0.02v (20mv). Note to test all Lifos batteries’ voltage over 24 hours after
charge to get rm values.
•Most mains lead acid battery chargers will charge the Lifos 105 but some smart
chargers might only charge up to 85%. If this is the case we recommend getting
a new charger, please see our website for recommendations on the FAQ pages.
However you will not cause any damage to the battery if using your old charger.
For DC – DC charging please also check our website for recommendations on the FAQ pages.
•Lifos 105 can be used if it is positioned on its side but will give best performance if it is positioned
with its terminals facing upward.
NOTE – do not mix new Lifos 105 batteries with old batteries, whether in series or parallel.
Storage of Lifos 105
Lifos 105 battery has an extremely low rate of self-discharge but if you intend not to use the battery
for an extended period of time please charge it 50% to 80% prior to storage. It is recommended to
re-charge the Lifos 105 once every 3-6 months.
NOTE – allowing the battery to over discharge (+6 months since its last charge) can lead to a
shortened life, or even damage the battery.

Accessing the Lifos App
The App is available for all Apple and Android devices. Search the Apple App
store for Lifos and down load for free. If using an Android device go to Google
Play search Lifos and down load for free. The App will give you full visibility of
your Lifos 105 battery and its performance. Your device connects to the
Lifos App via Bluetooth so you need to be within 10m of the battery to access
its data. Each time you wish to view the data you will need to log on
via the App but this is quick and easy.
If you are using more than one Lifos 105 battery, you will not be able to
identify each battery separately if they are in close proximity to one another.
If you have connected your batteries in parallel then you only need to look at
any one battery (it does not matter which one) to see the total power for the
complete battery bank (SOC).
If you have connected your batteries in series then you also only need to look
at one battery to see the total power for the complete battery bank, however
you will only see the voltage of the battery bank from the single battery and
not the battery bank as a whole.
If you have any questions about this connectivity please visit www.lifos.co.uk
for help.
NOTE – only one Apple/Android device at a time can be connected to
each battery.
Lifos 105 battery load limitation
The Lifos 105 battery is perfectly suited to heavy DC loads such as motor movers, but its Battery
Management System (BMS) will not allow any load higher than 120A or 1350w at 12.5vdc or 1200w at
230vAC through an inverter. It should be noted that inductive loads, even if rated at 800w may not
be powered by the Lifos 105 because the inrush current of these devices can often be many times
the rated load during initial start up. Examples of inductive loads are microwave ovens.
Resistive AC loads (via a suitable 12vDC to 230AC inverter) that can be powered by Lifos 105
include: toasters, travel kettles, travel irons, hair dryers, heaters etc (Max 1200W).
NOTE – in the event an AC load higher than 1200w is connected to Lifos 105 the battery will shut
down and will not power the device but the battery will not be damaged because its BMS will
protect it. In this circumstance the Lifos 105 will be instantly reset so it is able to power loads within
its approved power range as noted above.
Connecting up your Lifos 105 battery
Your Lifos 105 battery has removeable battery pole terminals.
Generally the pole connections are great for quick release connections found in caravans, RVs and
boats. However if you unscrew the pole connections you will then be able to use ring terminals
directly onto the battery.
When connecting to the Lifos 105 using the bolts and washers provided, we recommend a torque
setting of 8Nm.
Please connect the Positive (+) connection rst before connecting the Negative (–) connection.
Disconnection is the reverse process, Negative (–) rst, Positive (+) last. (This is standard
disconnection procedure for connection and disconnection of batteries and will help to avoid
short circuits).
