Page 5: What Else Is In The Box
What’s inside a Roamer battery? The Roamer HOME battery consists of sixteen 105Ah 3.2V grade A LiFePO4 cells connected in series to create a pack with nominal voltage of 51.2V and charge capacity of 105Ah. This provides a total energy capacity of 5.38kWh. Cells offer an industry leading 4000 cycles @ 80% depth of discharge and are rated for a continuous charge and discharge of 1C (105A). -

Page 8: Installation
Your battery should be installed lying flat with the Roamer logo the correct way up, or upright with the Roamer logo facing upwards. If the battery is installed in a vehicle, then it is crucial that the battery is securely fastened down so that it cannot slide while the vehicle is moving. -
Page 9: Connecting Power Cables
48-105HOME batteries in parallel will have a total capacity of 210Ah, a peak delivery current of 200A, and a nominal system voltage of 51.2V. • It is possible to connect to 15 HOME batteries in parallel. • We do not recommend connecting HOME batteries in series. -
Page 10: Connecting Rs485 Link Cables
Connecting RS485 link cables When using multiple batteries in parallel, you should use the link cables provided (or any other standard RJ45 ethernet cable). You should use the two ports on the right side of the battery as you look at it, labelled as RS485 / Link in the diagram. Connect one end of the link cable to one RJ45 socket on the first battery, and the opposite end of the link cable to the corresponding RJ45 socket on the next battery. -
Page 11: Connecting Your Battery To A Pc
Connecting your battery to a PC Roamer provide windows PC utility software to monitor the status of your battery and configure system parameters. First, you’ll need to connect the provided USB to RS485 adapter to the 9-pin D-SUB to RJ45 cable. They should mate together easily using the captive screws to make a secure connection. -
Page 13: Discharging
The recommended maximum inverter size that can be used with multiple Roamer HOME batteries are given in the table below. If you are installing multiple batteries in parallel, you can connect a larger inverter. To allow for unbalanced loading on the batteries, we recommend limiting the total discharge current to 80% of the total rating from all batteries added together. -
Page 14: Charging
Charging You should choose a charger or inverter-charger with an appropriate default (or configurable) LiFePO4 charge profile. The Roamer BMS will automatically prevent you from overcharging the battery by blocking further charging when the high voltage threshold is reached. This is an emergency protection however and should not be relied upon as a substitute for an appropriate LiFePO4 charger. -
Page 15: Low Temperature Charging
Low temperature charging Standard LiFePO4 batteries should not be 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 if the internal battery temperature reaches below this point. -
Page 16: Monitoring State Of Charge
Monitoring state of charge The state of charge (SoC) is tracked by the BMS by monitoring the current flowing in and out of the battery, combined with additional information about self-discharge, internal losses, and cell condition. This can be viewed through the PC software or via a connected monitoring system. -
Page 17: Storing Your Battery
Storing your battery If you happen to need to store your battery for an extended period – 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 52.0V and 53.0V (equivalent to 40% to 80% state of charge) and fully isolate the battery from any chargers or loads. -
