Needs some volts and amps for your 24 trolling kicker ?

[Crosbyman]

this little $20 module should supply a 24v from your 12v battery if you mostly slow troll.
it can give you 15- 20 amps and no need for a second battery.

Don't see how that is going to work very well

Specs list 20Amps max and with 15Amps add cooling fan which will draw power

【Output Power】Input voltage * 20A, such as: input 12V * 20A = 240W, input 24V * 20A = 480W，input 60V * 20A = 1200W Note: Do not use the short-circuit output method to adjust the current. It is recommended to use a smaller adjustment range.

So 480 watts won't give you mach and note that is max, so running at that it probably won't last long

This should be an interesting debate.

When it sounds to good to be true....it is !

Trolling motor spec:
PWM Frequency: To avoid audible humming noises, it is recommended that PWM controllers operate around 15–25 kHz.

The unit in question operates at 150KHz

15-20a? I got a small watersnake and that draws 45a max . What happens if you give it a bit much wellie ? , fry the unit and leave you to row home ?
Just an observation but the 12v motors seem to go about 1 lb thrust per amp draw . Most electric outboards here are rated in lb's of thrust ....which tells you nothing ....like whats that in hp so I can get a rough idea of size req , and how much current so one can size cables and batteries.
I just sussed it as a lb per amp after looking at various specs from different manufacturers and saw a bit of a pattern .

Far out , should be able to ski behind that

just a suggestion gents... a slow troll means low amps maybe 10 ampsx24v . I am not suggesting max power on a 24v kicker ! ..150khz should not create any audible noise power wise. Us old boaters probabaly don't hear much above 12 khz Young ears can catch 18-20KHZ violins . Most phone services only carry the 300-3200 hz band of speech.

again..just a suggestion gents...if anyone wishes to try it. btw that unit is the same as used to build a pulser circuit to clean injectors like ETECs needing 50-55 vdc)

Crosbyman....once again your very "elegant" with your words and your "offerings" to all that might need it.

Auditable noise isn’t the issue.

PW supplies and controls are notorious for EMI emissions. Cross talk with “Maximizer” controls and sonar are a common problem

How clean is this supply?
I’m running CHIRP @ 80-160 kHz. Don’t want a trolling motor banging away at 150 kHZ

case closed then.
