Hi, I would like to know that what is the maximum possible voltage and current for the mBot ranger to use as a power source? (external battery/adapter)
In the manual I found that the voltage should be 9-12V, but my external power source sometimes output voltages like 12.8V, is this a problem?
And what is the maximum recommended current? Could be a problem for the mBot ranger or for it’s components (ultrasonic sensor, arduino board, etc.) if the current from the battery would be 1-2A?
For example I have found this battery.
Is it suitable? Or can it damage the product?

Think about it, or if you have much money try it 
If the output voltage is higher then the recommended voltage range - what do you think?
Yes select a different one which has an output voltage of 9-12V e.g 10V …
Current limit is mostly important for the charging of the battery. There is a regulator in the Auriga - so I guess that is not a problem. Anyway the sensors will not draw high currents - that can happen only with the motor, or in case of a short circuit…
