Ive just bought a 450pro v2 and was looking for any advice on batteries.

The standard setup is supposed to be able to take a 4s lipo.

What's better - a decent 3s 45-90C or a 4s 40C?

3s would be 2200mah and the 4s would be around 1800mah. Is there much difference in flight time? Difference in performance?

Any advice welcome.

Adam

Very high, very fast, too much money, no you cant have a go!

can't really mix/match those two setups. They will at the very least require different pinions. usually 4S setups use in the range of a 3000kv motor where the 3S setups are in the range of 3700kv motors.

my experience is with 4S you get a better running, cooler running batteries. if the motor is geared correctly it'll run well. The ESC needs to be able to handle the 4S setup. I did it with the stock Align ESC and it worked but I put a separate BEC so the ESC wouldn't get too hot. I think the Align ESC is only rated for 4S if it is not using the BEC.

C ratings on battery packs are 75% marketing hype IMO. better to judge a pack based on it's internal resistance and how many flights it'll run before IR starts to go higher.

A 4S 1800mah pack weighs about the same as a 3S 2200mah pack. They will both give you about 4 minutes of flight time, same headspeed. 4S setup bogs less when you get aggressive.
