User Manual
IMPORTANT: PLEASE READ BEFORE FIRST USE
LiFOS Quick User Guide
The guide should be read in conjunction with the main instructions included overleaf,
but the following points will enable speedy deployment of your LiFOS battery.
1. From new, please discharge LiFOS fully before connecting to a charger.
2. LiFOS can be charged by a solar panel (via a suitable charge controller), vehicle alternator and
any lead acid or lithium phosphate battery charger. However, certain chargers are unable to
charge LiFOS to 100%. In this case use the LiFOS charger supplied with this battery (or another
approved charger – see www.lifos.co.uk for the approved list).
3. The Battery Management System (BMS) within each LiFOS 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.
4. If two LiFOS batteries have been purchased (for two different uses or to connect two in parallel)
please ensure the app is fully closed down on your smart phone on the first battery before
searching for the second battery. Unless the app is fully closed there will either be no visibility of
the second battery or the information given by the app will be corrupt and very inaccurate.
If you have any questions regarding the use or operation of your LiFOS battery please contact the
LiFOS help line on 01684 774000 or see the FAQs on www.lifos.co.uk

‘Smart’ Battery Chargers
Your LiFOS battery can be charged using any battery charger and alternator that delivers
no more than 30A. In a few cases a ‘smart’ battery charger can only charge LiFOS to 90%.
In this case, we have provided a LiFOS lithium battery charger that can be used in these
circumstances. If using this charger please connect the ring terminals to LiFOS using the bolts
supplied and observe the correct polarity – red to red and black to black.
Plug the adaptor into a mains wall plug and once the LED on the charger goes from red to
green it indicates the battery is 100% fully charged. Disconnect the charger and use the LiFOS
as described on the attached.
If you have any questions about this process please contact us on 01684 774000.

LiFOS Battery Load Limitation
The LiFOS 68A 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 80A or 1000w at 12.5vDC or 800w
at 230vAC through an inverter. It should be noted that inductive loads, even if rated at 800w may not
be powered by the LiFOS 68 because the inrush current of these devices can often be many times the
rated load during initial start up. Examples of inductive loads are micro wave ovens and motors.
Resistive AC loads (via a suitable 12vDC to 230AC inverter) that can be powered by LiFOS 68 include;
toasters, travel kettles, travel irons, hair dryers, heaters etc (Max 800W).
NOTE – in the event an AC load higher than 800w is connected to LiFOS 68, 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 will be instantly reset so it is able to power loads within its approved
power range as noted above.
Connecting up your LiFOS Battery
Your lifos battery has removeable battery pole terminals depending on how you wish to connect
you battery.
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.
Please connect the Positive (+) connection first before connecting the Negative (-) connection.
Disconnection is the reverse process, Negative (+) first, Positive (-) last. (This is standard disconnection
procedure for connection and disconnection of batteries and will help to avoid short circuits).
Disposal
Disposal of a used or damaged LiFOS battery must be done at a certified recycling
location. There are many of these nationwide – please see www.lifos.co.uk for details.
Warranty
A LiFOS battery is supplied with a 5-year warranty from the date of purchase (please keep your proof
of purchase) or 2750 battery cycles, whichever comes first. Note a full battery cycle is determined by a
fully discharged LiFOS (down to 10% of its gross capacity) and charged to 100%. The 5 year warranty
period assumes no more than one full cycle per 24hr period. In the event of a valid warranty claim the
manufacturer will, at its discretion, supply a new or re-conditioned LiFOS battery dependent on how
many years have passed since the date of purchase or how many cycles the battery has undertaken.
Conditions
a. Any warranty claim can only be validated by a proof of purchase.
b. The warranty is invalid if the battery has been subject to misuse, abuse or physical damage.
c. This LiFOS battery must be of the correct size, design, and capacity for the intended application.
d. The battery should be installed and operated at a temperature not exceeding the batteries design
limits as noted on the previous page and on the battery itself.
e. The warranty shall be voided if the battery becomes unserviceable due to: fire, freezing, abuse,
alteration, modification or it suffers from an over discharged state.
f. Installation of the battery must be performed by a responsible adult.
Thank you for purchasing this advanced lithium iron phosphate (LiFPO4) 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 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 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 –.
•Do not short circuit LiFOS otherwise permanent damage could be caused.
•LiFOS can be connected in parallel but not in series (you cannot connect two LiFOS batteries
to create a 24v system). A maximum of two LiFOS batteries can be joined in parallel and it is
important that when two LiFOS batteries are thus linked they are at the same level of charge (ie
<0.005v of each other) - check the details of each on the App to confirm this and if one is higher
than the other, charge both batteries fully so you can be certain they are at the same level.
•Any mains lead acid or lithium charger (max 40A) can be used to charge LiFOS or a 12v solar
panel with suitable charge controller or a vehicle alternator. If a “smart” battery charger is used
it is possible LiFOS will only be 90% charged so in this instance we recommend using the LiFOS
lithium battery charger supplied with this battery. For Dc to DC charging, please check the list on
back of these instructions or check our website www.lifos.co.uk for most up-to-date list.
•LiFOS can be used if it is positioned on its side but will give best performance
if it is positioned with its terminals facing upward.
Storage of LiFOS
LiFOS 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 fully charge it prior
to storage. It is recommended to re-charge the LiFOS once every 6 months.
NOTE – allowing the battery to over discharge (+6 months since its last charge)
can lead to a shortened life.
Accessing the LiFOS App
The App is available for all Apple and Android devices. Visit www.lifos.co.uk
where a link will take you directly to download this App for free. The App will give
you full visibility of your LiFOS 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 two LiFOS batteries whether
independently or joined in parallel, you will not need to down load the App twice.
When your mobile device is searching for the battery it will see two different
serial numbers. Each LiFOS has an individual serial number printed on top of its
casing so you can quickly determine which battery the App is showing you the
information for. You simply switch between each serial number as required.
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.
