Default Batteries fora 55lb Trolling Engine

I've just received a new 55lbs trolling engine,

Can I have some recommendations for a suitable battery also would I be better off with one 110Amp Battery or two 85Amp Batteries

I can't recommend specifics on where to get a batter / what brands, as I'm in the US.

To the question of 1 battery or 2, I'd say it depends on specifics of your use. Do you own the boat or are you hiring one? How much do you fish, and on what size waters? Do you use a boat that has a petrol outboard and the electric is just for fishing use, or is it the primary power?

Assuming you don't own a boat, the biggest issue with 110+ AHR batteries is that they're heavy. Loading and unloading them could be a real undertaking depending on how close you can get your car to the boat and the docking setup.

BTW, in general I think more = better when it comes to battery AHRs. If you can get a 115 or 120 Ahr for little extra money, I'd do so.

At the very least, I'd recommend getting a good folding cart if you'll need to carry the battery any distance to get it to and from the boat.

But with that said, two 85 AHR batteries is going to have its own set of problems. Now you have twice as much care and feeding. If you ever need to charge the batteries overnight for consecutive days of fishing, you'll either need two battery chargers or you'll have to rig up a set of jumpers so that you can charge both batteries with one charger.

I'm also going to speculate and say that two 85 AHR batteries could well weigh more in total than a single 110 AHR battery. I could be wrong, but it's worth thinking about because it just adds to the hassle factor.

If you don't already have one, I'd also say budget for a good battery charger and in my boats that don't have a built in battery compartment, I always put batteries in a plastic battery box to keep them out of the weather and if they should leak, the box contains anything that spills. Also, if you do any higher speed running you need the battery box to have a hold-down strap.

A lot of sensible advice there.

Thanks for the advice, its appreciated

The water I'm going to be using on is mainly my clubs waters and their boats so to be honest, Its not going to be to far to carry. All in about 100 yards


As petrol engines are not allowed on the water it is going to be my primary pwer source

I've seen these two

Caravan Batteries, Boat Batteries & Leisure Batteries - Ultra Plus 12v Sealed 120ah Leisure Battery

Caravan Batteries, Boat Batteries & Leisure Batteries - Lucas 12v 125AH Ultra Deep Cycle Leisure Battery

Alpha batteries are superb and the service is top notch
buy(according to budget) the one with the most discharge cycles and maintain it. A charger that charges on maintenance mode helps.
The previous mention of a box is a good idea pricey at 30 blabs from their site
Poundstretcher do a plastic box that is the identical size with a lid for a fiver .Drill two holes for leads on top and you are sorted with enough room for spare pack of fags and lighter!

Uhhhh, say what? Look, maybe it's just me, but after seeing what a couple of drops of battery acid did to a pair of gloves, I'm thinking I don't want to be putting anything in my mouth that's been riding around next to a lead/acid battery. Maybe that's just me.

Totally agree re the battery maintainer. I'm going to add on-board chargers/maintainers to my boats next spring, really like this concept and I think it will give the batteries a longer service life overall.

I have a similar question as have aquired a minn kota turbo 36lbs to be used on local reservoir in 12 foot club boats. Is an 86a battery Ok or should I go for the heavier 110a?

How many acres is the loch. if it less than 50 then you will get away with the 85ah

Default Power requirements

If you intend to motor up for drifts all day on a reasonable size water you probably need two batteries based on my own experience using a min-kota 46 Th and a similar Yamaha EM fishing a 440 acre lake using a 110amp and a 85amp auxiliary.There is a lot of fishing at anchor takes place on this particular lake so if we are motoring about and fishing at anchor most of the day the 110amp does it in spades.So right about the weight.Best to have a means of wheeling to the boat.Make up some kind of cradle/strap for lifting as these batteries were not really designed to be carried about much and I just d'ont trust the moulded handles because battery will not work to well under the boat pontoonHave fun it is a great way to fish for trout.

There are a lot of variables, but if you can handle the weight, no one ever regretted having too much battery power. Ideally, it would be best to ask other anglers at your lake to see what they're using.

Wind conditions, the size/weight of the boat, number of anglers, size of water, type of use, size of the electric motor, etc all are factors that play into how long a battery will last.
