High output LiPos loose their burst ability towards the end of their flight time. The weight versus available power ratio is moving towards the negative and weight is becoming more of a factor. If you punch the throttle in rabbit when you are below 15V, you may get the low voltage warning but it will go away when you go back to throttle neutral. This is the sag in power I’m referring too.
Having the extra amps with the GiFi battery makes the H run smoother over all. The weight difference is only 2.5 ounces. The latch is a bit sketch but I’ve learned that lesson so I’m extra cautious on the install. Price is decent also. So far, so good.
