Matt13: I had the unfortunate incident that should never happen but happened still. My 10S pack slipped out of the velcro bands. On a downline they slipped forward, releasing themselves and on the next upline got disconnected altogether with the leads so no more power. Without a receiver pack the plane would be lost.

I only use 30-35 mAh per flight so on a 800 mAh pack even after 10 flights it is only half empty. So the receiver battery is never an issue, always full enough for a few flights.
