POWER MANAGEMENT SYSTEM
BATTERY INFORMATION
the Orca H9 is equipped with a power management system to prevent accidentally running
out of battery charge during use:
• At 50% charge remaining - maximum power is limited to level 5
• At 40% charge remaining - maximum power is limited to level 4
• At 30% charge remaining - maximum power is limited to level 3
• At 20% charge remaining - maximum power is limited to level 2
• At 10% charge remaining - maximum power is limited to level 1
Nominal voltage = 48V @ 60% [50.4V fully charged] per battery pack
• Capacity = 20AH per battery pack
• Peak discharge current = 80A

Usually caused by excess loading or partial
jet-blockage. Turn off immediately & allow to
cool.
If error reoccurs frequently, return to
manufacturer for repair.
Fatal system error. Unit malfunction.
Make note of code number (1-5) and return it
to manufacturer for repair.
To perform a hard/factory reset (note: when there are errors on the display screen, or it has some
problems in the operation, a hard reset can apply), press and hold B-LEFT and B-RIGHT buttons
simultaneously for 15 seconds. Leave unit for approximately 2 minutes and then restart as normal.
