Re: [Electric Boats] Re: minnkota wiring

 

As I live in the Netherlands I do not know the vendors and favorite brands in the US of A.So you have to look for yourself and/or be advised by the wizzkids in the shop.
Minn Kota has motors 12 or 24V and up to about 70A I believe.
 
Your speedcontroller is thus 4 or 7 cells or better (They only think in Lithium being 3.7 V)
"they" have operating times of 5 to 10 minutes. So look for the "continuous" rating. That is about 50 or 60% of the advertised performance on the box
You can watercool (OEM or DIY) and depending on its effectiveness you can draw much higher currents.
 
You need to actuate the speedcontroller with a servotester or (very posh and comfortable) by RadioRontroll.

Hey Carel,
Can you elaborate on your statement and maybe show some vendor links on what can be done with the RC controller parts.
I have a kids size remote control boat that is a lot of fun... I am wondering if we could scale that up to a 50 foot long boat that could be controlled remotely too!
My current research is leaning to an old ferry hull with dual motors with about 10kW each output if you can make suggestions in that ball park. Charging would be dockside and via a solar array.

Share some of your experiences if you would. If anyone else has any input on these systems, please also share with the group.

Many thx
Bill
