battery voltage strange behaviour when using battery.getConverted() on MKR Motor Carrier

[gbr1]

Hi!
I have connected a 2s battery to the carrier.
I discovered that:

• using (float)battery.getRaw() / 77 I obtain 7.41V
• (float)battery.getConverted() gives 7.00V
• (float)battery.getFiltered() gives 7.00V
  Using an external voltmeter, measure is 7.41V

Why getConverted method doesn't return 7.41V?

Thank you in advance!

Thanks for your report @gbr1. The reason is that the developers used an integer type in the library source code. Clearly that is not an appropriate API design for these functions.

Fortunately it is only a convenience function and the user is still able to calculate a usable battery voltage value in their own code as you did.
