4s vs 6s

[jamie]

I am looking at building another hydro for sport/fun running and was wondering what would be a better combination 4S 2200kv@ 32,560 RPM or 6S 1450kv@ 32,190 RPM.
Im looking for lower amps/less heat and both are 4082Y wind motors in a 30 inch Hydro. 200 amp esc with around M445 to M645 props.
My thinking is that the 6S would be a bit better package all round, but wanted to get some more experienced views on it thanks.

I always go with the higher voltage myself..........

If you are looking for the same speed with both setups, then using 6S means lower amp draw, lower temps, and longer run time.

this compleatly depends on what battery packs your planning to use/buy. would you be using a single 6S pack, or two 3S in series? how much battery weight can you handle in the boat?

[jamie]

3S 2S and room and weight should be ok compared to 2S 2S about 300 Grams more.
Why would it make a difference running 6S1P or 3S2S ?

[jamie]

Also would running 6S help to run a bigger prop if needed easier than 4S ?
Thanks for the replies

The higher the voltage the less amp draw for same wattage

6S is 22.2 volts, 3S is just 11.1 volts. It makes a huge difference in performance and a small one in run time. What "C" rating and capacity and make are your packs?

I think he's asking what difference is one 6S pack vs two 3S packs in series.

Thats correct still 6S just the series connection from 3S packs ....22.2V total.
