Safety
Roamer have taken every precaution to ensure that our batteries are
as safe as possible and give you complete peace of mind while using
our products. No battery is 100% safe however, and caution should
always be taken when handling or operating equipment containing, or
connected to, high-capacity energy storage devices.
LiFePO4 batteries should only be installed and operated by a
competent person. Please read this manual carefully and pay particular
attention to the recommended charge, discharge and temperature
limits as these may be dierent to the Battery Management System
(BMS) maximum limits.
Please read the separate Safety User Guide carefully. This contains
essential safety information and best practice on how to use your
battery. If you have any concerns or questions about safety, please do
not hesitate to contact Roamer at support@roamer.com

Quick start guide
We’ve put together a summary of the installation
process to help you get started straight away.
Installation
Your battery should be installed in a location where it cannot be exposed to extreme
temperatures, moisture or vibration. If possible, install your battery, inverter and
chargers in the same area to keep cable lengths to a minimum. If installed in a
vehicle, fix the battery securely using brackets or ratchet straps bolted to the chassis.
Connecting cables
Our batteries are supplied with female M8 terminals and corresponding bolts. Cables
should be finished with copper tube M8 ring terminals, we do not recommend using
battery post adapters as these are not suitable for the sort of sustained high currents
possible with a Roamer battery.
You should also avoid connecting more than one cable to each battery terminal, if
you need multiple cables at the same voltage then you should install busbars and
connect one cable to each stud. Make sure all connections are tight and unable to
shake loose, we recommend using a torque setting of 10Nm.
Install the Roamer BMS app
Our SMART batteries can be monitored in real time using the free Roamer BMS app
for iOS or Android. During installation, make sure that you allow Bluetooth and GPS
connections when prompted or you will not be able to connect (don’t worry we do not
collect your data). You can use the app to check the state of charge, individual cell
voltages, current draw, and any fault codes.
Please note that the state of charge reading may be inaccurate until the battery has
completed 1-2 cycles, including a full discharge to 0% (10.8V for a 12V battery or
21.6V for a 24V battery). This does not aect the operation of the battery and you can
continue to charge the battery when the state of charge suggests it is full, as long as
the battery voltage does not exceed 14.2V.

Charging
For safety reasons your battery will be shipped at a low state of charge so you
should charge your battery on arrival. Battery chargers should be configured with a
LiFePO4 profile. Boost/absorption time should be 1 hour, and equalisation mode and
temperature compensation should be disabled. Do not leave the battery unattended
while charging and do not allow battery voltage to exceed 14.2V. Please read the
charging section of the user manual carefully.
Long term storage
If you are not ready to install your battery yet or you will not be using it for a while, we
recommend charging the battery to between 13.0V and 13.25V (40% and 80%) and
then isolating it completely from all external loads and chargers. If you really need to
keep the battery turned on when not in use and your charger has a storage mode,
you should set this to 13.2V. It is not necessary to trickle or float charge as Roamer
Batteries have an extremely low self-discharge rate of just 3% per month.
You should also monitor your battery voltage occasionally and ensure it does not
drop below 12.8V, if voltage drops below this then you will need to top up the charge.
You should fully cycle your battery every 6 months if storing for an extended period.
Recommended Charging Voltages for 12V and [24V] LiFePO4 Batteries
Absorption/Boost – 14.2V [28.4V]
Float – 13.5V [27.0V]
Storage – 13.2V [26.4V]

What’s inside a Roamer battery?
Roamer only use the highest quality components including factory original grade
A cells purchased directly from top tier manufacturers. We also provide cell serial
numbers for complete transparency and traceability. These are logged by Roamer
before shipping and are printed on the factory test sheet and via the QR code on the
battery case. This can be scanned to view the serial numbers.
Our custom high-power BMS and Roamer app give you complete protection and
visibility of what is going on inside your battery, and our premium balancer circuitry
helps keep all cells perfectly in line for a long and healthy life.
Your battery is professionally constructed using precision engineered brackets, CNC-
cut epoxy insulation board and high-capacity busbars and cables. We take immense
pride in the quality and reliability of our batteries, but we also make them fully
serviceable in case of problems or if an upgrade becomes available. While the case
can be opened for repairs and upgrades, please do not try to do this yourself without
speaking to Roamer Technical Support as you will invalidate your warranty.

Installation
Your battery can be installed in any orientation, including on its side. If installing
in a vehicle, then it is crucial that the battery is securely fixed down so it cannot
slide while the vehicle is moving. It must also be accessible so it can be removed
or disconnected in an emergency. We recommend having tools readily available
including cable cutters and a socket wrench of the correct size.
You should install the battery in a way that avoids exposing it to extreme hot or
cold temperatures and facilitates an even temperature distribution across the
whole battery pack. If installing the battery on the floor of a vehicle, you should fit
insulation and/or an air gap between it and the floor’s surface as this will prevent
cold bridging from the metal sub-floor. Our XTREME series are extremely tolerant of
low temperatures and can be charged quickly even in sub-zero temperatures but
caution should still be taken when used in extremely low temperature environments,
particularly where the batteries are not installed in an insulated location.
Your battery comes supplied with M8 bolts, flat washers, and spring washers. You
should therefore terminate your battery cables with copper tube ring terminals with
an 8mm hole. The cable terminal should be placed flat, directly onto the battery
terminal. Next place the flat washer, then the spring washer, then feed the bolt
through this stack. The bolts should be tightened to a torque setting of 10Nm. Loose
connections can introduce contact resistance which will cause the termination to heat
up during high current flow. This is a serious fire risk and must be done correctly. If
you are upgrading from a lead acid battery with clamp posts, we recommend
re-terminating your cables as described above, instead of fitting screw-in battery
posts. These are not appropriate for the high current flow possible with your battery.
You should only have one main cable connected to each battery terminal bolt. If
you have multiple chargers and other components to connect, then you should use
busbars or a distribution system. Too many cable connections on one bolt adds
excessive resistance, which under high current flow can become extremely hot. You
should ensure that this risk is minimised by only installing one ring terminal on a
single stud or terminal. Shifting any complex connection points away from the battery
reduce the risk of starting a battery fire.
Be very careful not to short-circuit the positive and negative terminals. The resulting
current surge could cause damage to the battery and any external components it
flows through. Double check the polarity of the battery and any equipment before
connecting them. Connecting a battery the wrong way around can cause irreparable
damage to the battery and any components connected to it.
