Looking for the best auxiliary battery for a converted vehicle?

Opt for the highest-performing auxiliary battery on the market in terms of energy storage: the lithium battery! With a capacity of 200Ah, it is the indispensable ally for your road trips, while being significantly lighter than a lead-acid battery at equivalent power.

This new version takes things to the next level: it is now equipped with integrated heating sheets. No more stress about charging in extreme cold — your battery takes care of everything to stay operational, even when the temperature plummets.

Smart technology to tackle winter

The Ultimatron LiFePO4 Smart BMS battery integrates an automatic heating function that activates as soon as the temperature drops below 0°C, provided an external charging current (approximately 7A) is applied.

• Zero battery consumption: The heating system uses only the energy from the charging current, thus preserving your autonomy.
• Extreme performance: Thanks to this system, the battery can be charged in environments down to -35°C.
• Total protection: The integrated BMS (Battery Management System) continuously monitors voltage, temperature and current to protect your cells against overcharges and overheating.

Your battery under control with integrated Bluetooth

Monitor the status of your installation in real time directly on your smartphone or tablet using the Ultimatron France app. You will find the charge level, voltage and temperature of your battery.
