iPilot runtime question
For those of you with an iPilot, how long could can you keep it running or on spot lock before it drains your batteries?

I have an 80#, 24 volt and it usually only lasts 2-3 hours when running constantly. Could this be due to running the lowrance gps and radio at the same time? Still seems like something's wrong.

All batteries tested around 13v. Ideas?

Need bigger batteries is all I can say. My buddy has a 112# on his 24' boat and it lasts all day (like 8 hours all day) in a stiff wind.

Need to look at the ah on your batteries, they should be over 100 for great battery life. Shouldn't be dying after a couple hours.

I have the same trolling motor. And I can run 6 or 7 hours. It's on a light boat though. Get new batteries and check your charger.

re: iPilot runtime question
so a different 12v deep cycle battery would make a difference even if my current batteries are good? I never put much thought into shopping around for batteries.

Yeah I have two 27 or 29 series deep cycles they work really well

Just testing voltage of batteries doesn't tell you their status. Need to put a load tester to see if their good. Everyone should have one of these! LINK
If good may need to step up to larger size batteries group 27 or 29

I have the 24V 80lb Ultrex. I would easily say that spot-lock can last me 4+ hours staying on.

I have the green interstate marine batteries FWIW.

Also I watched Brandon Palanick (so?) Spot-lock yesterday for three hours straight in a stiff wind on Mille Lacs.

Buy the highest reserve capacity (RC) you can afford, I use the 3 Cabelas AGM on my iPilot and can troll all day long.

re: iPilot runtime question
Possibly. The reserve capacity of a battery is a good indication of how long it will last under load. If yours are small batteries and the motor is on a big boat than you might just not have enough pounds of battery in the boat to make it work even though they're showing 24 volts. As a general rule of thumb the heavier the battery is the longer it will last.

What size is the boat?

re: iPilot runtime question
First off, you should not have your radio and GPS hooked up to the same batteries as your trolling motor.

Mine will run for days but I have 2 group 31 AGMs . Way overkill, but I take my rig on week long camping trips. SAMs Club batteries are the best deal. Most likely you need new ones.

This! Nothing besides trolling motor is to be hooked to them. Run it to cranking battery or a house battery.

Also I'd jump up to size 27 batteries. I have a 24v 80 lb I pilot on two group 27s and I can run it all day in bad winds or current with no issues. Sounds like your batteries are bad. It should go all day or even more.

This. Hook all your toys up to cranking battery. Only trolling motor should go to your 24v setup.

20' skeeter bay. The batteries were on the boat when I bought it a few months ago. A sticker on them says MCA @ 32 deg F, CCA @ 0 deg 650, minutes @ 23 amp 225.

Also part number is 29HM. Duracell battery. Not sure if that's the group. This is all I could gather from the pics the wife sent while I'm at work.

Also the electronics are probably hooked up to the cranking battery.

re: iPilot runtime question
Switch all the gizmos to the cranking battery.

Cranking amps and reserve capacity are related but not the same thing. Cranking amps is how much juice the battery can put out for a brief period, I think 30 seconds. 225 minutes at 23 amps is your reserve capacity but it's stated in a weird way. Seems like I remember the batteries I deal with (marine diesel so a little heavier duty) are usually 80 amps for around 120 minutes or so. Meaning, it can discharge 80 amps for 120 minutes continuously before it shits out.

You have small batteries and they're probably old as well which is a double whammy.

ETA: never mind, reserve capacity is usually stated in terms of 25 amps at 80 degrees. I knew there was an 80 involved somewhere. I'd say a set of bigger fresh batteries on their own circuit would solve your problems.

Group 29 is not a small battery....

But it does sound like they have bit the bullet. Like everyone has stated your going to need three batteries in all.

One cranking and gizmos and 2 trolling motor batteries.

Best scenario is to have a perks switch wired so that if your cranking battery dies you can switch over to on of your trolling motor batteries and not have a ruined day

re: iPilot runtime question
Idk anything about battery groups. I just know CCA and reserve capacity.

I don't get how a GPS and a radio (assuming he doesn't have a big amp or anything) would make an appreciable difference on trolling time. Both are very tiny loads compared to a working 80lb trolling motor.

re: iPilot runtime question
That looks like a pretty good battery (from a quick search)...are u sure your charger is doing its job? Any idea how old they are?

re: iPilot runtime question
And whether or not it started as a good battery or not is not much of a difference. They all go bad after a while.

It's more for short protection than anything. Also pulling a higher load in one battery than the other can put a strain on the system.
