how long would you estimate it would last on a minakota 27 lb thrust and how many times can it be recharged looking for light weight battery

Get a AGM 35 amp hour wheel chair battery. Nice and small/ light, and lasts a long time. I use one to power a motor guide 55 lb thrust varimax. It lasts as long as I want to fish, has an extremely long shelf life. Mine is over 4 years old so far.

Check around, you should be able to find them for $60 - $75. AGM batteries are about the best you can get.

You might wat to look at one of the Cabelas portable sonar batteries. 12V and rechargeable many times. I've used one on a rental rig with the same power motor you are talking about. It lasted all the while I was fishing - but I didn't use it all the time - rather just to reposition the boat and getting to the next spot on a small pond. I know it works; I just do not know how long it will last. But it certainly is small and very inexpensive at only $25.00 a pop. You could get two and you'd still be ahead of the game compared to a normal size battery. Just a thought that you might find worth looking into. :)

As far as your lawnmower battery goes, the device (any) doesn't much care where the power comes from, as long as it get the power!

I use my 12v lawn mower battery to run my electronics and lights, and a regualr deep cycle 24 for my MinnKota 30lbs TM.

Don't think you'll be happy with the performance a small battery provides you, not to mention you'll end-up over discharging the battery, and with the discharge/recharge cycle (being only so many cycles built into the life of a battery) shortening the battery life a bunch.

Go to SprawlMart and buy a Deep Cycle Marine Battery made for the job, there's a reason guys don't use small batteries for trolling motors, they aren't made for it.

Find an Interstate battery center in your area. They have the deep cycle batteries for the powered wheel chair/scooter chairs. Those batteries are designed for the cycling, discharge/recharge of trolling motors (or wheel chairs). Other batteries will not do the job. They WILL not last. A DCM0040 is a 40 amp/hr sealed battery not much bigger than your lawn mower battery. That would be my bet. 7 3/4" x 6 1/2"

Weight directly correlates to how long the battery will last.

oh my acheing back. don't care if i only get a year out of the battery, I like the idea of a wheel chair batttery I'll check it out. thanks but the model number would be nice . I've got about 50 foot from my cabin to the water an 80 pounds is more than I can handle

Sounds like you need a off-raod wagon to ahul the gear in. Ya know, a Red Rider with 12" tires.

Rich ... why not get the biggest series that'll fit in the space available, and have someone carry it down to the boat for you ... leave it there, in the boat, and run a electric line down to it whenever you need to charge it ?

Hey, I know what you mean about packing them big honkin' batteries ... my boat is over 50yds from my apt, so I bring both batteries in to charge them. They come out of the boat & into the truck, out of the truck & up the stairs into my place ... then in reverse order whenever I go fishing. :Doh: rotfl

Pap, i have the same problem. Found that a stayncharge system would work wonders for me. I get a good charge on the way to the lake and on the way home. Might want to give em a look. Stay'N'Charge by Retrotec (http://www.stayncharge.com)

lots of good ideas.. keep them coming I'm sure there are more ole guys that need a helping. yes I do have electri on my dock but it's used for my bigger boat not my pond prowler. would need to get another onboard charger , but we got theve's that help them selves to what ever they see.
