Lifos Go 200Ah 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 Go 200Ah battery.
1. Your Lifos Go 200Ah will be supplied partially charged. Please ensure the battery is fully
charged before rst use.
2. Lifos Go 200Ah can be charged by a solar panel (via a suitable charge controller), vehicle
alternator (via a suitable DC to DC converter) and any lead acid or lithium iron phosphate
battery charger. However, certain chargers are unable to charge Lifos Go 200Ah 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 ofcial Lifos Battery Charger.
3. The Battery Management System (BMS) within each Lifos Go 200Ah 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 Go 200Ah.
4. If more than one Lifos Go 200Ah has been purchased and you wish to connect them in
series, parallel or both please see page 1 of this manual for detailed instructions.
5. Always use appropriate sized cable and fuse (on all positive cables) connected to a Lifos
Go 200Ah. This ensures the electrical circuits within the load and the battery are protected
at all times. Fit the fuse/s as close to the Lifos Go + terminal as possible. If in doubt consult
a qualied electrician for advice.

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 Go 200Ah 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 Go 200Ah 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 Go 200Ah otherwise permanent damage could be caused.
•Lifos Go 200Ah can be connected in Parallel (Fig.1). You are able to connect
up to 4 Lifos Go 200Ah batteries in parallel giving you a battery bank capacity
of 800Ah (200A x 4).
•Lifos Go 200Ah can be connected in Series (Fig.2). You are able to connect up
to 4 Lifos Go 200Ah 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 Go 200Ah can be connected up in parallel or series when needed but
only in the below congurations:
Please note – when connecting multiple batteries, fully charge each
battery and allow at least 6 hours to “settle” and then check each is within
50mV of each other. Once all are within this tolerance they may be connected
to one another.
•Most mains lead acid battery chargers will charge the Lifos Go 200Ah 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 Go 200Ah 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 Go 200Ah batteries with old batteries, whether in series or parallel.
Storage of Lifos Go 200Ah
Lifos Go 200Ah 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 Go 200Ah once every 3 months.
NOTE – allowing the battery to over discharge (+3 months since its last charge) can lead to a
shortened life, could damage the battery and invalidate your warranty.

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 Go 200Ah 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 Go 200Ah 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 Go 200Ah battery load limitation
The Lifos Go 200Ah 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 150A or 1875w at 12.5vDC
or 1500w at 230vAC through an inverter. It should be noted that inductive loads, even if rated at
1875w may not be powered by the Lifos Go 200Ah 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 Go
200Ah include: toasters, travel kettles, travel irons, hair dryers, heaters etc (Max 1500W).
NOTE – in the event an AC load higher than 1500w is connected to Lifos Go 200Ah 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 Go 200Ah will be instantly reset so it is able to
power loads within its approved power range as noted above.
Connecting up your Lifos Go 200Ah battery
When connecting to the Lifos Go 200Ah using the bolts and washers provided, we recommend a
torque setting of 8Nm.
Please connect the Positive (+) connection rst before connecting the Negative (–) connection.
In all circumstances, an appropriate sized fuse must be tted to all positive cables being
connected to the + terminals of Lifos Go 200Ah as failure to do so could result in damage to
either load circuit or Lifos battery in the event of an accidental dead short etc. Please consult a
qualied electrician if guidance is needed regarding fuse or cable size appropriate to your load.
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).
