B) Startup Procedure
1) Charging the Battery
The rechargeable 9 V block battery included in the
VARIOBOT kit, unlike conventional 9 V alkaline
batteries or NiMH batteries, can deliver a current of
up to 600 mA. It provides power to variAnt for a
minimum of 3 hours.
Average power consumption: approx. 160 mA
Peak current for both motors: 400 mA
The battery has two 3.7 V lithium-ion cells.
However, its electronics simulate a typical 9 V
battery at the output. During operation, the voltage
drops to around 5 V, at which point the battery
shuts off to prevent deep discharge.
Before using it, fully charge the battery by
connecting it to the Micro-USB port.
While the battery is charging, the LED indicator
will be red. Once the battery is fully charged,
the LED indicator will turn blue.
Charging time may vary depending on the current
battery level and can take up to 2 hours.
Key specifications for the VARIOBOT battery:
Output voltage: 9.5 V - 5 V
Maximum output current: 600 mA
Capacity at the output: 4500 mWh
USB charging voltage: 5 V
USB charging current: 0.5 A
Voltage of the internal Li-Ion cells: 3.7 V
Capacity of the internal Li-Ion cells: 1200 mAh
Weight: approximately 28 g
If your kit does not include a Lithium-Ion 9 V
block battery that can deliver 400 mA of
current (which is necessary), we recommend
ordering one from www.variobot.com.
