It's a long story but I might be having to run an Ace pot puller off of a battery that I'm only able to charge on shore. If anyone has done this, how's it worked out? I know there's a lot of variables like depth, pot weight, battery size, etc, but have you been able to pull your pots on one charge?

Using the numbers from Ace website...

140 feet/min using 600' of line is about 4 minutes of hauling per set, unloaded, so use 5 minutes
It uses up to 35 amps when loaded up
That is 35 amps for 5 minutes, or 3 amp-hours
A group 31 battery at 12.5 volts is good for about 90 amp-hours
IF you don't want to kill the battery, it should only be 50% discharged, so 45 A-h useable capacity

That means you can haul at max draw maybe 8-9 times before you must charge your battery. Real world conditions mean that this would actually be less than expected, so I would say 5-7 times hauling would be about all you should do. But, it should be enough.

How big is your battery? I assume this puller is designed to run on 12V.

Also what's the chemistry of the battery? If it's lead acid, then as mentioned above you shouldn't drain it below 50%. The newer lithium varieties however can be drained much lower though.

Thanks for the replies guys. I don't have the battery yet, might use an extra one I carry in a different boat or buy a dedicated battery for it. It's to be used on an inflatable that is at a remote cabin. The outboard doesn't have a charging system.

Since you aren't committed to any particular battery yet, you may want to take a look at a LiFe (Lithium Iron) battery. As I mentioned above, you can get a lot more use out of a given size battery and they're way lighter and more portable than the lead acid batteries.

Thanks, I'll look for one.

Don't forget you need a LiFePo4 battery charger. The charger you have may not work.
One other thing LiFePo4 battery are ship between 30% / 50% charged they must be charged before using them.

Keep in mind that draw down on a battery is only about 50% (flooded), unless you plan to kill the battery, which will severely shorten its life, Realistically speaking a group 31 (~100AH) will only yield about 50 useable amps. that will give you a theoretical 1.4 hours, but I would expect 30 to 45 minutes more likely.

These pullers are power intensive, you would need a pretty big bank of batteries to pull more than once. Sometimes the pots get hung up, sometimes there is a current, if so it takes longer and at a higher load.

Thanks. I'm pretty much only needing two pulls. Will charge the battery on shore, pull two pots, then return to recharge. The lithium battery sounded good till it was pointed out it needs a special charger.

Do you have a plan “B”?

In case your not able to retrieve the pots using the pot puller?
