I'm running a 6V, 2300 mAh NiMH battery in my Raptor 50.
Full charge, the voltmeter reads 6.7 to 6.8 volts under load.
In 4 to 5 flights, my voltmeter is reads close to 6V and I quit until I recharge.
My question is whether or not I am being too conservative. Can I safely fly down to 5 volts?
If I was running a 4.8V battery I would fly until I was near 4.8 volts.
I think you answered your own question. That is what I would do. I will let people with more experience in batteries be more specific.
