800A has to do with the absolute measurement capability of the FSESC components. This number has nothing to do with anything other than I * R = 1.65 Volts, where I = 800 Amperes and R = .2 milliohms.
200A is likely the maximum burst you could fit through the transistors for a very short period of time without damaging them. Like 2 seconds.
120A is probably the maximum long burst you could get out of the FSESC for 30 seconds to 1 minute.
The limitation is how heat travels from the switches to the outside environment, and conduction is probably not a well understood concept at Flipsky. I wish it was.
Hi, I have an easy time to foil with 120amp max. I am using FS65161 motor (100kv) with FR prop. Mast is Gong 65cm with Allavator L foil. Board and rider together might be around 120kg. Batt is 12s11p. Top speed is 32km/h.
Flipsky ships from China. You can get this controller from banggood - it’s even cheaper than flipsky. You can easly get -20% coupons on banggood too, and choose EU Priority line as shipping method - that should avoid taxes in EU.
Btw, flipsky is known for not so good warranty, one reason more to order from banggood.
