Bait Boat wiring

Projects General Guidance

Hi Guys!

I am not an Electricity Expert, i am not good in wiring to, but this wiring work?

So in nutshell: i want to use an 11,1V 3S 5000 mAh LiPo battery. I attach a HobbyWing 1060 Brushed ESC to it. This ESC have a built in switch, that i replace into a water resistance 2A switch. The ESC output wire directly to the 12V-24V max. 150W dc motor. The ESC's BEC power the arduinio, servos, and H-bride. I have a Flysky 6CH Receiver, each signals are processed by Arduinio. The two servo controlled by arduino too. On the H-bridge device there is a lower power output DC motor that run only on 5V. There is 1-2 LEd Strip from 5V too...

Is this good? Can it work? I want to avoid burning down ESC, Motor, Battery...

At full power, a 150 Watt, 12V motor will draw over 12 Amperes, and the startup (stall) current will be higher than that.

If it works at all, don't expect the LiPo battery to last for more than a few minutes.

The basic rule for run time of a new rechargeable battery is approximately (battery capacity in Ampere hours)/(average current draw in Amperes) or (capacity in mAh)/(average current in mA). Derate for battery age.

Battery life should be around 20 mins at full power. Should be enough to get the bait out and the boat back.

Please post schematic of your proposed wiring (a Fritzing wiring diagram is not a schematic).

Your main motor is connected to pin 13, which does not have PWM available so does not allow speed control of your motor. That doesn't sound right.

The harder part is going to be to deal with the currents and resulting EMI, heat in control electronics, etc.

Yes, sorry... I replug it into a PWM output :wink:
And i see, that there is no GND in Flysky Receiver, so i fix it too...

Sadly i cannot give you schematic (i am not an expert in this) i tought that Fritzing will be good.

Anyway, this can work?

  • There is no shortcut, there is no serious msitakes whit i can brun down parts?
  • The 2A switch in right position?
  • The 5V and GND wiring good into devices?

Assuming it is connected to a water propeller life will be more complicated and simpler.

The propeller needs to be matched to the motor, otherwise the motor will either drive a small propeller too fast and cause cavitation or it won't be able to turn a too-large propeller fast enough. There will probably be advice about propeller choice on a forum that deals with model boats.

I reckon with a properly sized propeller it is unlikely that the motor will be used at full power. And the startup load for a propeller won't be high if the motor has speed control. Also, I assume the boat is intended to move gently so as not to disturb fish.
