Why not an onboard charger? I love mine.

Buy cheap smart chargers.

Anything that won't overcharge your batteries.

It doesn't take more than a few seconds to hook up a battery... But it costs hundreds to buy on board chargers.

I have 4 chargers for a fraction of what it would cost to have inboards... I also don't need to occupy space in the boat for a charger.

Strongly disagree, to each their own.

Not every boat is setup with a dry location for an on board. These threads are typical though. OP says no on board.... And y'all give him no advice. Classic.

I fish quite frequently. I have 4 batteries in my boat. On board is not the only way. However you can feel great about yours.

Seems like a heated issue, Mr. Pike. On board chargers are nice, BUT if you don't want one, I have had good luck with Schumacher and Diehard automatic brands. How many batteries do you have in your 14ft. fishing boat, 1 or 2 at the most, right? So a portable, automatic charger wouldn't be too bad. MinnKota has a portable 2 bank charger that puts out 5 amps/bank for about $100.00, but then you are getting up towards an onboard price for a one bank. Guess you have to decide how much work it is to hook them up and unhook them. I haven't found it to be that big of a deal, but if I had 3 deep cycles and a starting battery, I'd not hesitate a moment to get the onboard unit. Good luck in your decision.

With battery chargers, my family and I have always had best luck with Shumacher products.

My neighbor recently picked up a Shumacher smart charger/maintainer at northern tool with the mailer coupons for I believe around 50 dollars after his other charger gave up the ghost. Nice little compact unit and he didn't want to spend the time or money to wire up his older boat with an onboard charger. Pretty much dummy proof unit that will automatically switch from charge to maintain so he doesn't have to worry about overcharging.

I have a two bank Minnkota on board that has work great for six years. I also have one of the newer Schumacher chargers which has worked great for three years. I have three chargers which have burned up over the last ten years including Schumacher's and Sears. I've also had pretty good luck with Harbor Freight trickle charges. Good and bad in all colors, so I wouldn't recommend one over the other. Just make sure it has overcharge protection.

Bottom line: Find one you can get by with and use it until it's gone.

My 2 cents.

I would rather spend less for a portable smart charger (plus it allows for other uses) rather then replace my dead on board charger. The reason I cannot do so is because how I have my batteries (24v) configured in the bow of the boat makes it a serious PITA to get the portables attached to the posts - where as an onboard charger I only have to grab the plug and plug it in. Some decisions need to be made by situation and the cheapest route almost never fits a situation - of course.

I can run mine over and buy more for $200.

Batteries charge all the same genius.

You do know most onboard chargers are waterproof right? So with 4 batteries do you have 4 chargers to hook up oor just one and keep moving it from battery to battery? I run an onboard so I can plug in 1 cord at 10pm when I get home and know all 3 are fully charged at 6 am the next morning when I unplug the cord and drive away....

Many of us don't have easy access to our batteries. My cranking is under the sink and during muskie season the rear casting deck is in so one has to crawl under that and lift a flap to even see the battery. Other 2 are in the center of the boat and easy to get to but why climb in to hook up 2 chargers when I can plug in 1 cord from outside the boat in 2 seconds and not have to worry about the charger being out of the weather since my boat has to sit outside... We all have a preference I chose quick and easy....

Schumacher has lots of different models... pick the one that fits what you want.

Definitely get one that is a smart/automatic charger, hook it up and the charger will cycle how many amps based on how much charge the battery needs. The biggest thing is it will automatically shut off/maintain when the battery is fully charged.

I got a Schumacher 2/6/12 amp at Fleet Farm a few years ago. Cheap, small, and has served me well. I use that for the trolling motor battery and a battery tender jr. for the starting battery.

We have a 2 bank Minnkota 10amp on board charger that charges our TM batteries on the go.It charges the front batteries only after the starting battery is fully charged.I rarely have to use a portable charger as by the time I get back to the dock the maximizer on our bowmount says they are fully charged.I have double checked by hooking up the portable,it's a Schumacher & usually tells me they are 85% charged.The 1.5-2 mile run out to the lake the next time takes care of that.

Glad to hear you settled for the Schumacher, Mr. Pike, since I will be buying one, probably this weekend. My Diehard automatic met its death yesterday when it accidentally fell off of a high shelf. Tried it on 3 different batteries after the fall and it is VERY erratic. Don't want to risk a garage fire or it taking out my deep cycle battery. Nothing lasts forever. Enjoy all your new "investments" over the weekend.

I feel if you have a 24v system then the on board is great.

I used to charge each battery with Smartchargers for a few years, wasn't going to buy a onboard. Until I got the 24V trolling motor, I started rethinking the onboard charger. Finally found a really sweet deal on a 3 bank and bit the bullet. I love it, probably some of the best money spent for maintaining batteries and will buy another in a heartbeat.

An onboard is not for everyone but I sure like mine.

      It’s done automatically.  You might need an actual person to clear that log in stuff up.   Trash your laptop history if you haven’t tried that already.

      Problems with Yetti

      By rundrave · Posted

      we had some nice weather yesterday and this conundrum was driving me crazy  so I drove up to the house to take another look. I got a bunch of goodies via ups yesterday (cables,  winch ratchet parts, handles, leaf springs etc).   I wanted to make sure the new leaf springs I got fit. I got everything laid out and ready to go. Will be busy this weekend with kids stuff and too cold to fish anyway, but I will try to get back up there again next weekend and get it done. I don't think it will be bad once I get it lifted up.    For anyone in the google verse, the leaf springs are 4 leafs and measure 25 1/4" eye  to eye per Yetti. I didnt want to pay their markup so just got something else comparable rated for the same weight.   I am a first time wheel house owner, this is all new to me. My house didn't come with any handles for the rear cables? I was told this week by someone in the industry that cordless drills do not have enough brake to lower it slow enough and it can damage the cables and the ratchets in the winches.  I put on a handle last night and it is 100% better than using a drill, unfortatenly I found out the hard way lol and will only use the ICNutz to raise the house now.

      I haven’t done any leaf springs for a long time and I can’t completely see the connections in your pics BUT I I’d be rounding up: PB Blaster, torch, 3 lb hammer, chisel, cut off tool, breaker bar, Jack stands or blocks.   This kind of stuff usually isn’t the easiest.   I would think you would be able to get at what you need by keeping the house up with Jack stands and getting the pressure off that suspension, then attack the hardware.  But again, I don’t feel like I can see everything going on there.

      Problems with Yetti

      By rundrave · Posted

      reviving an old thread due to running into the same issue with the same year of house. not expecting anything from yetti and I already have replacement parts ordered and on the way.   I am looking for some input or feedback on how to replace the leaf springs themselves.    If I jack the house up and remove the tire, is it possible to pivot the axel assembly low enough to get to the other end of the leaf spring and remove that one bolt?   Or do I have to remove the entire pivot arm to get to it? Then I also have to factor in brake wire as well then. What a mess   My house is currently an hour away from my home at a relatives, going to go back up and look it over again and try to figure out a game plan.           Above pic is with house lowered on ice, the other end of that leaf is what I need to get to.   above pic is side that middle bolt broke and bottom 2 leafs fell out here is other side that didnt break but you can see bottom half of leaf already did but atleast bolt is still in there here is hub assembly in my garage with house lowered and tires off when I put new tires on it a couple months ago. hopefully I can raise house high enough that it can drop down far enough and not snap brake cable there so I can get to that other end of the leaf spring.
