SMART4 battery be powered-on. Install the Roamer BMS app SMART4 batteries can be monitored in real time using the free Roamer SMART 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). - Page 6 13.2V. It is not necessary to trickle or float charge as Roamer Batteries have an extremely low self-discharge rate of just 5% per month in standby, and almost nothing when turned off via the power button.

Page 7: What Else Is In The Box
What’s inside a Roamer battery? Roamer only use the highest quality components including matched 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. -
Page 9: Installation
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. -

Roamer first. If you want to change any settings on your battery (for example to change charge parameters to match a specific inverter or to install in a hybrid setup) please contact Roamer support at support@roamer.com. -
Page 13: Data Communication Ports
The default protocol is for Victron Energy BMS-Can but this can be changed in the Roamer SMART app. Roamer can supply the cables you need to connect to these ports but if you need longer cables or have other specific requirements, its possible to make up your own cables - please contact Roamer Support for the wiring pin-out diagram. -
Page 14: Victron Gx Integration
When connecting any cables to the battery, ensure the battery is first powered off. Next, take your Roamer CAN cable, and line up the slot inside the M12 connector with the slot on the connector in the battery, the cable should point towards the middle of the battery. -

230Ah, a peak delivery current of 300A, and a nominal system voltage of 25.6V. • Up to 16 battery modules can be connected in parallel with the SMART4 series. If you want to monitor all batteries, these must also be addressed within the Roamer app and the data-link cables installed for communication between modules. -
Page 16: Discharging
Pre-charging involves slowing down the inrush current, thereby filling the capacitors with charge in a steady and controlled way. The SMART4 range of batteries have a pre-charge circuit built in, this is activated when the battery is turned on, for up to the first 10 seconds. -
Page 17: Charging
The ideal charge profile for your battery involves bulk charging at a constant current up to a target voltage of 14.4V 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) if this cannot be disabled. -
Page 18: Low Temperature Charging
Low temperature charging LiFePO4 batteries should not be fast charged at temperatures below 0°C as this can permanently damage the cells. Roamer batteries therefore include a low temperature charge protection function in the BMS which will prevent you charging once the internal battery temperature reaches this point. -
Page 19: Troubleshooting
If using an Android device, you will need to provide all security permissions including location (this is to enable the use of Bluetooth Low Energy, Roamer do not collect your data and we do not track your location). - Page 20 Q) My battery won’t charge / discharge A) First step is to check the Roamer SMART app. Are there any protection modes active? There are many reasons why the BMS would go into protection mode but the app should provide enough information to be able to rectify the problem.

Page 21: Monitoring State Of Charge
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. There are subtle differences in the voltages of different batteries so the below parameters are for reference only. -
Page 23: Storing 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. With SMART4 batteries, you should also press and hold the power button to turn the battery off entirely. -
