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.

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.
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.
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.
• We do not recommend connecting more than 4 batteries in parallel. Where possible, a single higher capacity battery is usually safer and easier. • We do not recommend connecting more than 2 batteries in series. Roamer also sell 24V and 48V batteries if required.
(or charger) to energise the DC system. For example, you could use a DCDC charger powered by an engine alternator. Please note that your Roamer battery BMS includes a surge current protection feature, if you attempt to connect the inverter without pre-charging then your battery may enter full protection mode with an error code of ASCD.
The ideal charge profile for your battery involves bulk charging at a constant current up to a target voltage of 14.2V and then stopping. The active balancer in your Roamer battery means an absorption or float stage is not required although we recommend a short absorption period (up to 1 hour) to ensure battery is charged to its absolute maximum capacity.

This protection will remain in place until the temperature rises back above the release temperature to prevent charging and discharging right on the threshold. Due to XTREME series batteries using smaller, less bulky cyclindrical cells than SMART series batteries, it takes less time for the internal temperature to match the ambient temperature, and for all cell temperatures to equalise.
MUST accept all security permissions, this includes GPS on Android phones. We do not collect any customer data. The Roamer BMS can only connect to one device at a time, if you install the app on multiple devices then you must force close and disconnect the app on the first device before attempting to connect on the second device.

BMS dashboard The dashboard gives you the main overview of your battery. The top ‘clock’ display shows you the estimated state of charge and amp-hours remaining. Please note that this state of charge reading is just an estimate, if it has not been calibrated recently then this could be incorrect.

(within 0.1V). The only exception is when the battery is at 100% state of charge. If you notice that there is a significant difference between cells at any other time, please contact Roamer as this may indicate a problem with your battery.
You can verify this on the Roamer BMS app home page, look to see if either charging or discharging button is turned off (button will be greyed out if off – this means it is in protection mode). If it is in protection mode, then check the protect state page for the corresponding error code.

Where possible, please also provide screenshots of the home page of your Roamer BMS App, full details page, and the protection state page.
Monitoring state of charge The Roamer BMS app should keep a fairly accurate track of the state of charge of your battery but it is helpful to have a second point of reference for comparison and troubleshooting. You could install an external shunt based battery monitor and battery capacity can also be roughly estimated from the voltage.
Storing your battery If you happen to need to store your battery for an extended period of time – for example through the winter months – we have a few recommended tips to prolong the life of your battery. • Before putting into storage, you should discharge it to between 13.0V and 13.25V (equivalent to 40% to 80% state of charge) and fully isolate the battery from any chargers or loads.
