For my 1967 wooden Boat which I fully reworked, I have designed and built an outboard engine. It is a 85165 fully waterproof BL Innerrunner, capable of 18Kw (according to the maker) As I can run only 4,4Kw becuase of local laws, it will be a long lasing motor I hope. I am running it on a 14S1P...

I am using this resitor; https://www.conrad.at/de/p/hochlast-widerstand-6-8-axial-bedrahtet-5-w-tru-components-tc-prw05wjw68jb00203-1-st-1583571.html no heatso far, but I did not put any load to the system, just switch on/off several times. About C1, this one does not have to be higher voltage...

Today I tried again with a switch. Now in fact it is working. Sorry for the confusion

Well, as mentioned the esc had full power before I could switch to the 10Ohm resistor

Battery voltage is 14S Liion so around 54V capacitance is 6x 560µF I can not measure the time. And I did not use a switch, but a wire to manually "do" the switch. So my switching time might be longer than 1 sec. In this time the controller already got full voltage, before I "switched" to ON...

Did anyone built this one? I am waiting for the parts.

I used this Mosfets Infineon Technologies IRFB7730PBF MOSFET 1 N-Kanal 375 W TO-220AB And yes I am sure I have built it correct. Did it 2 times. Same result, in the moment you open the switch from the "off" pos, the esc is switched on.

Well I have build it. And it does not work

what part is suitable for Q3? Q1 can be the same as Q4,5...?

This circuit does not work. As soon as you open the switch from the off position, the controller gets full voltage, Seems the 10Ohm is useless.

When you switch on, you connect + to - via 200k ??

I cant see this cap in your pcba, did you skip it?

nice, what current are you using it with cont.? And can this recuperate?

Thank you. Is this a reliable and good controller?
