How long will a Stratus PRXv2 bat last?

[DKirkpatrick]

Hello. Just deployed one of these, but don't have a battery charger port in the airplane. Can I expect 4 hours of battery capacity? It's paired with an iPad.
Coaching much appreciated.
thanks

Look up the amp-hour capacity of your battery.

Look up the amps that the stratus draws.

Divide the former from the latter to get your answer in number of hours.
