Lipo battery question, 20c enough?

[marko500]

Is 5s too much for a 8xl? The specs I got from the Hacker website says 1973 Kv, 4-5 Lipo, 60 amp operating current,1700 watts peak. I sure don't want to burn anything up,yet. This is also running a FD turbo Trans if that makes any difference. I don't know enough about this to be doubting anybody I'm just confused.

If you run the Transmission on a 1.3 gear ratio you will reduce the amp load on the motor with the same prop running direct. If you have not bought the motor I would use this Product ID: fei-580-L
Feigao 580L "Long" Sized Brushless Motor
And run it direct on the cat
I prefer to run large low rpm/volt motors and use higher voltage within the limits of the motor to obtain what I desire in large hulls for sport boating. My 2 cents

I would invest in two 4s1p 4300mah packs with atleast 20c rating for that setup. Two of these wired parallel (4s2p 86,000mah) would be safe for sport running and racing. You could also use both of them in the SV27 and UL-1 wired parallel (4s2p) for loooong run times. Of course you could use just one 4s1p pack in the low amp draw SV27 and UL-1 boat, but with shorter run time.

These 20c lipos will work, but something with a higher discharge rating of 20c would be even better.
