Master the Frost

When cell temperatures drop below 0°C, the WattCycle 12V 314Ah Mini self-heating battery automatically activates its integrated heating module once connected to a charger.

To safeguard your battery's health, the self-heating feature prioritises heating the cells to an optimal 5°C before charging begins.

This smart thermal regulation ensures a stable and secure energy supply, even in the harshest sub-zero environments.
