Boat: Apparition Catamaran (800mm)
Prop: 38mm x 1.4
ESC: SeaKing 180A
Motor: Leopard 3674 2650KV 2.5D
Batteries: 2 x Turnigy 5200mah 2S 30C (Series)
I originally ran this setup with a SeaKing 120A ESC and it was getting up to 140F, and the caps were hitting in the 165F's. I don't quite understand why the ESC was getting so hot. The motor was around 100-110F and the batteries were around 100F. I ran the same motor and ESC in a shovelnose hydro with 2 x 4200mah 2S2P 65C (Series) batteries, and everything was around 90-95F, and this was on a 42mm x 1.4 prop. The boats weigh about the same.
I have been reading about how to calculate the amps from the motor, and then trying to match the ESC and batteries, but I just don't quite know if I am getting it. As the scenario above confuses me.
Can anyone help explain this, and if this is a decent setup for my boat? I would much rather run the 120A ESC, as the 180A is a very tight fit. I have linked all the electronics to their specs. Also, what do the caps actually do, and why would they get so hot?
Thank you!
