On a F-16 jet with small movements on the flying surfaces I think you should be safe, although flaps/breaks down and a lot of speed will draw some current. I do know that a freind of mine (in my club) lost his 3.3 meter Yak with the exact same setup. He was drawing around 20 amp at that time in silly tight diving snap rolls. He used the Hitech 59xx titan gear servos.
I do know he switched to lithium manganese after that and it was ok (although on another planes as the first one was destroyed). As I said, I do not think you will get that high. Check your current and check how high you are. For your backup to be safe you should be above 2C sustained for more than 1 sec for your setup to be fully redundant as your backup is much weaker than your main battery.

Hi guys!
I have recently switched to Fromeco Relion packs in my SM F-16 1:6, a 5200 MaH pack as the main battery and a
2700 MaH pack as backup. Yesterday, I spoke with one of my jet friends here and he warned me that if pulling a lot
of amps the Fromeco (or any LiIo) packs will drop the volt below Weatronics cutoff values and I would have a lockout.
I have heard that this can happen with big 3D prop models with a lot of servos, I fly the F-16 with 3 servos only, and
I fly the FB Panther with the same packs and 5 servos - ailerons, elevators and rudder. Does anyone have any
experience with the Fromeco batteries/Weatronic or any other receiver and a battery management system?
Thanks,
Tor
