Default Lightweight 36volt Set-Up

EDIT: I POSTED THE 36VOLT I-PILOT TERROVA 101 IN THE SWAP BOARD TO TRADE FOR A 24VOLT, IF INTERESTED GIVE ME A SHOUT


The problem is that a 36 volt is way overkill for my little 16' boat that only has 60hp to push it around.

My question is what kind of three battery system can I run to keep weight to a minimum?

I can't have 200+ pounds of trolling motor batteries on the boat and expect to get on plane with the boat already loaded with fisherman and gear.

And before REW suggests it.......I'm not spending $5,000 on lithium batteries lol

I also might just try to trade it for a 24 volt Terrova instead.

could go with 3 24 series batteries. I have not looked up the weight, but would think it is about the same of 2 31 series batteries.

I was also thinking maybe something like this??

https://www.batterystuff.com/batteri...350-D5722.html

Three of them would be 100+ amp hours and weigh just 78 pounds.

Or I could go the next size up for more amp hours (and obviously weight).

I as well three plus years ago could not pass on a 36v terrova deal that has ipilot link.
I am running a 16'+ alumacraft tiller competitor with a efi 50hp 4stroke

Its way over-kill for most of my needs, being that I kind of hobby around with inverters/solar & many batteries, I had some china AGM's sitting around. These are 75Ah batteries sold to be used with sump pumps that offer battery backup. What I do like about them is they are a lower profile battery 8.25" x 14" x 7 3/4" and fit well in the location I installed them.

These batteries are sold by the Campbell Hausfeld or Wayne brand name, btw wayne charges about 2x the price for the same battery as the campbell lol. Again they are nothing more then cheap imports that thus far have held up well & have not been removed from the boat since installed three + years ago, boat also stored outside exposed to the temps of summer & winter.
Another CL purchase when they were brand new in the box the cost of lead scrap

Not suggesting to pick these up unless you can find a deal, point is there are many other options including smaller group 24 wet-cells, or other sealed AGMs that are used for UPS backup systems that are around 80Ah or something like a enersys data safe 12HX300 which is a 284W/about 80Ah battery.

Being they are AGM, they will withstand any vibrations simply due to how AGMs are manufactured.

Keep an eye on the local CL as they seems to appear on a regular basis with little risk in cost not much over lead scrap values. When UPS battery banks show a weak cell or two, the normal practice is to scrap the whole bank with the addition of new batteries.
Most of the time, those used batteries are in 90%+ health and only 3-five years old seeing very few load cycles during their lifetime

Back to the terrova, It is great having that extra power and when I raise to main motor, I can cruise fast leaving good size wakes, the gains in run time via 36v & about -25% battery capacity imo is a wash, but the power the 36v motor provides is not, well worth it even on a smaller boat

You are selling the wrong thing. Keep the bowmount, sell the boat.

Kind of like when your wife buys a new $10 purse and then needs to go buy a $350 dress to match it.

here you go, But I would be looking more towards 50Ah+, but then again it depends on how hard you plan to use them in a day

https://minneapolis.craigslist.org/a...010102507.html

look at the weigh in comparison to other 35Ah batteries, they are still 36lbs each, they pack these full of lead & the spec's are real unlike some

wrong, the amp hours does not increase when they are in a series
Therefore you have about 28 usable amp hours with a 35Ah battery setup before you risk damaging the battery by a DOD of more then 80%.
BUT, many of those batteries are also rated several hundred 100% dod cycles, but not garranteed, best to stay over 80% or even 50% for longevity of the battery if thats of concern
