Battery weight

My Optima BlueTop 34M 50 AH AGM weighs about 42 pounds, and far outperforms big heavy lead-acid batteries for safety, mounting options, deep discharge capability, no need for a battery case or outside mounting, etc. I'd buy one again, but this one is going strong after many years of tent-camping.

Lifeline group 27 is what I recommend.

camping not camper.

So what weight is your max do you think? Your problem will be recharging the trolling motor battery since it will run down in a few hours of fishing. I have 2 90AH ones I use and I swap them out while one recharges from a solar panel. You might find that the canoe uses less power than my pontoon though, so you might get two days. If you know your max weight you can handle it's pretty simple to identify the battery.

This.
What happens if you want to keep something in the RV running while you are out in the boat ?? A LOT of things won't work without 12 V power. That includes some propane appliances.

Get a proper battery for the RV and then whatever kind of junk you want for the boat; WalMart usually has good prices but you get what you pay for.

This isn't going to work.
Get one deep cycle battery for a camper, and one marine "hybrid" type for a motor.

House battery people usually have at least 90 AH, it weighs over 55 lbs but for a trailer weight doesn't matter. It has to be deep cycle.

Marine for your purpose can be 40-60 AH, less heavy. This one should be a hybrid, kinda in between deep cycle and starter battery. Get Optima Blue Top (or Yellow Top, don't remember the difference), if you can afford it. Though people with trolling motors often carry a cheap hybrid battery from places like Walmart.

I put a 2.5 HP 4-stroke motor on a canoe with floats/amas similar to yours. Weighs 30 lbs, runs 4 hours at trolling speed on one liter built-in tank. Though I'm on sea, lots of wind and currents, trolling motor would be too weak.

Lithium is an interesting idea, but I haven't heard of anybody using it on canoes. A small 20 AH for electric bike weighs 20 lbs and costs ~$900. The problem is that they come in 36, 48 and 52V, this is a typical voltage of a bike motor. Don't remember if there are any 12V. If you really want to spend a lot, get Torqueedo Outboard. It's a trolling motor with a proprietary Li battery. Expensive and not too popular.

I am looking for a deep cycle battery that I can use camping as well as use on the trolling motor for my canoe. Weight is the main issue. I can deal with any issues as far as battery life or how long it will run the trolling motor. The main issue is weight, so what is the lightest battery out there. I can't spend hundreds of $$$ but not looking for the cheapest thing out there either.

Well if you don't want to spend hundreds on a deep cycle lithium battery that is the lightest on the market than your stuck with lead acid or AGM type that is heavy, it would still be better to have a battery for the camper and the trolling motor, 2 battery's surly cant break your bank right.. :W

If you tip the canoe, there goes your battery. at best get a second battery for the canoe and leave the one alone in the camper. It would be bad enough to have your battery at the bottom of a lake, it would be just as bad to have your trailer battery at the bottom of a lake!

We rented a canoe once, and lost everything at the bottom of a river! Camera, clothes, food, drinks, everything with it tipped on us. Our kids said they'd never go in another canoe again.

Fast forward. Kids pretty much grown, no longer camping with us, and we purchase our own canoe. BUT! I got outriggers! They actually cost more than the canoe. We've NEVER tipped the canoe. It's so stable, I can stand and fish!

So, unless you have something like this, you really need a separate battery for the canoe. It will tip over ... sooner or later!

Maybe I should have been more specific. In addition to using the RV we also float and camp out of the canoe with a tent. I want a lightweight battery to use on the trolling motor and also use to charge phones and use the fillet knife when tent camping. Also, everything is in water proof bags or tote and they float so when you tip over (it happens but not often) everything floats. You just have to gather it up and go again. The battery is strapped into the canoe so it does not fall out.
