Backup Battery
We use a large-capacity 45Ah lead-acid battery as the backup power source, consisting of four batteries since the system operates at 48V.
When the engine is not running, this backup battery can supply power to the drive motors, allowing the machine to move easily during transportation.
When the generator is generating power and the drive motors don’t require as much energy, the backup battery can store the excess electricity.
Its substantial weight also acts as a counterweight, reducing vibrations and ensuring stable operation of the machine while helping to maintain an optimal center of gravity.
