If you fly a lot, how do you handle battery backup in Pro controller, especially in bright sun with the display at full brightness? Can you pop in a spare battery, or even attach a power bank via cable to maintain sufficient battery power for long days of flying fun?
Do you use a supplemental or spare battery? I plan to do hiking / backpacking trips with A2s and 8 flight batteries.
