You calling his dad a liar?
No it is not really too high (2300 kv motors don't go on a slow camera quad so I assume you are going to be doing faster harder flight). I had a problem with 40C- 80C, 1400mAh batteries sagging on a punchout when they were a bit low, and causing my voltage to drop (which could cause loss of video, LVC kicking in, or the FCB to turn off and disarm).
Well, some companies 'inflate' their C ratings just by having lower standards. If they decide that the battery can be safely used with a 25% voltage drop then so be it. But that does not mean higher C ratings don't exist. Many good companies have higher than advertised capacity and the voltage drop at their C rating is very minimal. Test them with whatever tools you have, or fly them. You can tell the difference in how the battery voltage drops (more linear or closer to exponential drop) toward the end. You can also tell the difference when you speed your motors up to counteract a turn and your video feed cuts out, or your ESCs turn off (BTW never fly with LVC enabled if possible) and leave you tumbling toward the ground.
Hahaha, amazing how much this hobby can teach you in a couple months.
