Unsure of what C rating lipo to get

[boater76]

I am unsure of what C rating lipo to get for my boat. I have a 18" hydro with a 60amp esc and a Turnigy TR 28-45 3600kv Brushless Inrunner. Thanks.

Id say minimum range is 20C and 4000mah

The highest you can afford.

Which packs are good from Hobby King? Zippy,Rhino?

I've used the Zippy Flightmax's all season racing / fun running with great success.

Some of the club members are running the Rhino's as well and they seem to be surviving the abuse also.

If your boat is only 18" long just get the biggest lipo that you can find that will fit in the space you have :)

Weight is an issue with small boats, especially hydros and cats. I would say to find out the amps that the motor pulls and get a pack that has a total c rating is 40% or more percent higher than the motor amps. For instance if the motor will pull 40 amps. Look for a 20c 3000 pack or 25c 2500 pack.

What is the calculation to figure that out Steve? Now what is the difference between the number of cells as well? I was going to go with a 2 or 3 cell.

I see some packs that say 3s1p. What does the 1p stand for?

Ken

The 3S is the number of cell voltage in this case 11.1V, the 1P stands for the number of cells in parallel. it could be 2P which would be a total of 6 cells at 11.1V

The 1P is totally unnecessary actually. P means parallel. If you had a 3S2P, it would be two 3S packs wired in parallel to double the mah.

[boater76]

Im looking to just run 1 pack. So to my understand i would just need a plain ol 2s or 3s pack right? Nothing with 1p or 2p? I am just not sure if I want to run a 2s or 3s pack. Any ideas on that? It's an 18" hydro with a 40a 3600kv motor with a 60amp esc.

Just a plain ole pack is 1P. Forget 1P, it doesn't mean anything. 3600KV motor you could run 2S or 3S. It will be a rocket on 3S. Watch your prop size! 3S on that motor will want a very small prop!

[boater76]

Think im gonna get a 3600mah 2s 30c, and get a 3s as well.
