Brushless trolling motor?

Post by gobi » Jun 22 2021 1:54pm

I bought a 30 lb minnkota from walmart for $93 today for my little row boat (folding plastic thing called porta bote).
I plan on running it on a little 12v LIFEPO4 battery.

As usual AFTER I bought this trolling motor I peeked at the forum for brushless trolling motor as I was stunned to see that the minnkota was NOT brushless.

Only garmin and lowrance have brushless motors which run around $2k plus,

Really? wow, trolling motor technology is still stuck in the 80s?
Are there any other sources for brushless trolling motors?

they have trolling motors and outboards, their outboards are quite well priced,

When you buy a $93 trolling motor from Wal-Mart you are going to get the cheapest thing China can make - which means a brushed motor and a one-FET controller.

true, but the lack of a brushless unit for the "ramen" budget guys was disappointing to say the least.
I have 48v batts and a bunch of 36v batts that I can use to power a 36v or 72v motor,

:?..Wow ! Does it really have a FET ?....or just a resistor + wiper .. :lol: :lol:

Nowadays a FET is going to be cheaper than a big pot!

Let's see for $93 - I need:

24 FET controller
1kw brushless motor
100% money back if I fail to catch fish.

Definitely not a pot. It's a selector switch so you can choose one of (say) eight different power levels. Each connects a different combination of those conductors.

If you have a 300 watt motor operating at half power, a pot has to drop the other half of that power. That's not something that's going to be inside a plastic housing.

I bought a DROK PWM motor controller after I watched this youtube video

the guy just sets the Minnkota to MAX i.e. 5 on the control and uses the PWM to control the motors power inline.
Love it,
The only problem I see is that the DROK PWM controller is NOT waterproof or water resistant and COOLING, I will have to add more cooling.

I will going to dry run this tonight, I will have to cut off the factor spades and crimp a quick connect.
