How long would this last on a full charge with a 30 lb thrust

Like, a bunch

The motor is old, but I only paid 20 bucks for it

Trolling motors are optimized for squeezing the most possible range out of lead acid batteries, which are usually shit for electric propulsion applications

They draw current at exactly the most efficient rate, they do all kinds of power conserving shit as the charge drops below a certain threshold, etc.

I have a Minn Kota and I'm routinely surprised by how long it runs on a regular deep cycle marine battery. It just goes all fuckin day, no problem, and the battery is a year old.

This motor will run for about 1.5 hours on full blast.
Also have a larger battery

Marine deep-cycle batteries are good for about 50% of the stated amp-hour rating of the battery.
So if that battery's rated at 100 amp-hours, multiply by 0.50, resulting in 50 useable amp-hours.
If that motor's drawing 10 amps, that battery will drive it for about 5 hours.

Automotive starting batteries are usually only about 20% amp-hours, since the plates are designed to provide high current for very short periods of time.

Find out how much your motor uses then use this calculator:

https://www.digikey.com/en/resources/conversion-calculators/conversion-calculator-battery-life

1A = 1,000mA
1Ah= 1,000mAh

Find out how many amp house (Ah) that batter is. Like 105Ah = 105,000mAh. In this image it would be a 105Ah battery with a drain of 4Ah motor which will last 18+ hours. Though, always cut that time in half since you don't want to destroy your battery. In fact 1/3 of that time would be better (6 hours).

How do I find out how much my motor uses?

You may need to hook it up to the battery and put an clamp-on ammeter on a wire to find out. You can get a cheap one from harbor freight.

Not sure why you got a 24DC....but my 27DCs will last about 4 hours full speed with my 55lb thrust motor until they start to fade considerably (top speed at full charge 4mph, fading charge speed = less than 3mph). I use three 27 series batteries and get about 25 miles total with them in my canoe. With a 33 lb thrust motor I'm not sure if your mileage will be better or worse.

sounds like a good practice question for learning electronics

I bought the battery on a whim. I noticed how the UPC stickers came right off so I removed the hundred-dollar battery sticker off and put on a battery sticker from a lawn and garden that was only 26 bucks. When they rang it up and said battery so boom I was out of there with a real good discount

lol....you asshole.

I may try it.

>>1091602
you operate 3 marine batteries in your canoe at the same time?

My batter only makes 5 pancakes how do you find the house

Do you hop?

>>1091672
i run 3 car batteries parallel

>>1092226
If I do that with marine batteries, should I get the same exact battery, or would one a little stronger be okay?

If you're chaining batteries together, its best to use the same size and age/capacity cells.

The general rule of thumb is that car (starter) batteries shouldn’t be discharged below 5-10% and deep cycle lead acid boat batteries below 20-30%, while AGM (absorbed glass mat) batteries can be safely discharged 50+% and also be recharged far more often.

There is really no reason nowadays to not use an AGM battery.

AGM batteries are fucking expensive

They’re more than a conventional deep cycle battery but not outrageously so and AGMs can be discharged further and recharged a lot more, so they’re cheeper in the end.

Easy one op, bring 2 batterus and when one dies plug in the other one and go back to where you started. Might help to bring a couple paddles

Egh, I have a foot one and thinking about doing it via hand sounds terrible. I guess if you need a workout...

I'm sure there's some calculations somewhere but I use a 50lb thrust motor with a bigger battery and I'm able to fish all day at Boerne Lake. I get in at 8am and leave at 9pm. Come home and still have 60% of the battery left. Granted I'm actually fishing and not just driving around all day. Stop for lunch, etc. When the battery starts going low you can feel it. The highest power seems to move you a little slower and you know it's time to start heading back towards the boat ramp.

(thought I'd bump this thread, as we're also talking about generators in another thread due to the hurricane)

You can put together your own "power pack" with an AGM batter or two, inverter, solar panel and controller, all packed in a Action Packer.
