MAX Continuous Current on MMM?

[BrianG]

legobrains: Knowing how Castle underrates their ESCs, I would expect at least 50% headroom for bursts. So, that 200A continuous would be something like 300A bursts. Just speculation here. But TBH, currents that high are inefficient and if very high power is needed, would be better off going with a high voltage and lower current setup.

BL_RV0: max current rating is a fuzzy thing to calculate. Not many setups will pull the max current all the time. Cars are peaky, so there are going to be high current bursts that level out for most of the run. But anyway, you can guesstimate the max current. Let's say a motor is rated for kv=2000, power=3000w, and max rpm of 60k. To get 60k rpm, you need 30v. To get 3000w at 30v, you need 100A. But then, you could go lower on the voltage and up on gearing to pull more current to get that same 3000w. rpms would be lower though as well. See how it gets kinda fuzzy? And then, the max power rating is usually for a relatively short duration. 3000w is a LOT of power for a small motor!
