Drop-in Lithium Leisure Batteries
SMART4 makes upgrading simple
Direct drop-in replacement for campervans and motorhomes
Roamer SMART4 batteries include several new and exclusive features that makes the process of upgrading from lead acid to lithium easier than ever before. You can now adventure further and for longer, with the confidence that comes with buying the best LiFePO4 leisure battery on the market today.
What makes Roamer
the best upgrade
With our 4th generation of SMART batteries, we've added several new BMS features, helping to make Roamer the number one lithium upgrade battery for campervans, motorhomes and boats.
Active Balancing makes Roamer batteries much more forgiving of irregular charging. You can use almost any lead acid charger, without risk of cell imbalance or BMS shutdowns.
Emergency Mode keeps a small amount of power in reserve and if your battery runs flat, you can remove the protection mode and wake up the BMS without needing a lithium charger.
Storage Mode reduces standby power draw to almost zero, allowing you to shutdown your system for months without running the battery flat. No need for a trickle charger over winter.
Several capacity options with standard G31 battery footprint or smaller. You can also maximise the space under the seat with our clever 230SEATBASE4 design or go big with up to 460Ah.
Enjoy home comforts
on the road
Lithium batteries are a perfect choice for those looking to bring their home comforts on the road. While the battery will give you a big power boost, it also unlocks the potential to add an inverter that lets you run power almost anything while off grid, from a kettle to a hair dryer, air fryer to a dishwasher. The sky is the limit!

“Most of the time we go off grid, we very rarely use campsites now.”
