Bluetooth Connectivity
Monitor your camper's deep cycle battery from anywhere in your rig. WattCycle’s Bluetooth-enabled system plugs directly into its built-in BMS—no extra shunt or module needed. Via our app, you’ll see real-time voltage, current, state of charge and temperature, so you always know your deep cycle RV battery’s health before heading off-grid.

Low Temperature Protection
European nights can dip below freezing, especially in mountain passes. Our LiFePO4 chemistry, paired with a smart BMS, automatically blocks charging below 0 °C to prevent crystal formation. That means your camping car battery stays safe from damage, and you wake up to a fully functional system, even after a frosty night.

Deep Discharge Capability
WattCycle cells deliver 6000+ cycles at 80% DOD (depth of discharge), outlasting lead-acid by years. This robust deep discharge performance makes it an ideal deep cycle battery for travel trailer use, whether you’re on a coastal tour or a weeklong back-country trek.

While traditional lead-acid batteries and AGM battery have served their purpose, LiFePO4 RV batteries offer a more reliable and maintenance-free solution, making them ideal for modern motorhome and camper van users.
In Europe, a standard Category B driving licence caps your rig’s maximum authorised mass at 3.5 tonnes, and most roads restrict vehicle width to 2.55 metres. Every extra kilogram you load—even from batteries—eats into your payload, affects handling on narrow lanes, and can push you over weight.
Traditional lead-acid banks are bulky and heavy, often adding several hundred kilos to your motorhome’s mass. WattCycle’s LiFePO4 packs, by contrast, are up to 70 % lighter for the same capacity—freeing up space and keeping your 6–7 m coach under the 3.5 t threshold without compromising energy reserves.
Whether you’re towing a caravan or a campervan, our slim-profile modules slot neatly under seats or into lockers, respecting Europe’s tight width rules. Even if you hitch a small trailer, a dedicated travel trailer deep cycle battery from WattCycle lets you power towables without blowing your weight allowance.
