Lund Renegade Bass Boat

[Hattrick]

But if you're happy with the 24V maybe you're on to something with your Humminbird setup, a fourth dedicated electronics battery might be a good idea.

[RenegadeBassin]

I am not really sure how 4 batterys could fit in there unless they upgraded the compartment? There's no way I could fit 4 in mine!

 

And thats before I rearranged it all to fit two power pole pumps

That was my assumption too.  Are you running all of your electronics off the cranking battery and two other batteries dedicated to the TM?  

 

Im trying to get my battery and electronics install figured out and squared away, don't want to do these things twice..

[J Francho]

Every boat I've owned, I run the graphs off the cranker without issues.

I am running 3 fishfinders, two powerpoles, and anything else as needed such as the aerator etc. on the cranking battery and I haven't had a dead battery yet. You just need to be smart about it and keep an eye on your voltage on your fishfinder, turn off stuff you aren't using, and charge your boat when its not in the water. Is it ideal? Maybe not for some people, but it works for me.

[Janderson45]

Thanks for the input guys, guess I'll probably do the same but keep a jumber box in the boat just in case.. glad to hear with 3 fish finders and other misc. electronics you haven't had any issues yet.  I'm just trying to do everything I can to make sure battery life isn't an issue constantly plaguing me..  I've fished with guys who are always having issues with cranking batteries or trolling motor batts dying and it's miserable- don't want to be one of those guys! 

[Hattrick]

I'll post a pic when I get one from dealer. My guess is they rotated the batteries 90 to fit

Renegade, what are the specs on your trolling motor batteries (amphours etc) just curious cause Im wondering if the dealer used smaller less capable batteries in order to make things fit in my boat.

I think if they somehow managed to fit 4 batteries they're probably group 24 size, maybe group 27... no way group 31s would fit.

 

I requested all group 31s, dealer said he would try to make them fit if at all possible and that it was probably overkill.

Here's the pic they sent me. Looks like they all fit well. Picking her up tomorrow morning. Will be installing my charger myself but should fit fine.

[Janderson45]

Sweet, looks like I should be able to get 4 in mine as well ! 

[RenegadeBassin]

Mine are group 27's and I had to hang them over the bildge area on a custom tray that I made to fit. They were to long to fit in that way with the back walls.

[RenegadeBassin]

[Hattrick]

Thanks Renegade, Yep mine are 27s also so everything worked out perfect and there's room for my 3 bank charger.  Here she is after I drove her home today.

Just for contrast, not because @J Franchois wrong, I'll offer these:

• I had a short in the charging cable for my trolling motor remote run my cranking battery completely dead.  That it was on a Canadian lake didn't help.
• I've seen interference from other things running on the cranking battery on my electronics (and other's electronics). 
• I've seen electronics shut off when starting the big motor with the cranking battery near the end of a long day.  I've seen this on more than one boat.

Because of the first bullet point above, and the fact that I am often on remote lakes by myself, I decided to isolate my electronics from my cranking battery to eliminate any risk of running that battery too low.  Works great, and as a side benefit, I've never seen better images on my electronics.  With the electronics completely isolated from the "boat" stuff, there's much less opportunity for any kind of interference.

 

All of the above have root causes than can be solved (or at least reduced) by methods other than adding a battery and charger and wiring for a separate system, and there's probably at least tens of thousands of folks who have done so.  I had the room and the money to add a 5th battery to my boat, it works great and it gives me peace of mind.  It is far from the only solution, and could easily not be the best solution...but it sure is nice...

[Janderson45]

If they could fit 3 27s and a cranking battery in hattrick's they can in mine too?  If that's the case I'll plan on two for the TM and one dedicated for my HB's.  I am of the same mindset when it comes to many of the benefits further north recapped above.

I don't mean to be prescriptive, or indicate that anyone who is running electronics off their cranking battery is doing even the slightest thing wrong...as I said there's at least tens of thousands of folks doing this who are just fine, and will be, forever.

 

It's just that what happened to me was sobbering...we had to go about 8 miles back to the lodge on a Canadian lake on the trolling motor at about 4:00 PM...after fishing on the trolling motor hard since 8:00 am that morning...had I not been running a 36 volt system, I'm not 100% sure we'd have made it back.  Would they have come looking for us?  Sure.  Could my boat and thousands of dollars in gear been pushed up on rocks by the wind and sunken/lost before they got there?  You bet.  Could we have been hurt along way?  Unlikely, but maybe.

 

I'm embarrassed to have had to deal with the situation, but it taught me to go belt and suspenders on the water, these days.  I hope others can benefit from my telling of the story.

 

...I also carry a portable jump battery.  probably belt, suspenders and an extra pair of pants...but I've got peace of mind...

[RenegadeBassin]

Maybe the battery compartment is bigger in the 1775? Hattrick's fit so if they offer you that option than I am sure you can do it as well! They definitely could have made it bigger for 2018 cause that was the one thing I didn't like about mine and maybe the received a lot of feedback saying the same.

[Hattrick]

I think it's the same size as the 1875 and same size as the 2017 models.  I noticed the difference with the layout is that my dealer slid the cranking battery all the way to the sidewall where your charger is located. That left room to put 2 batteries lengthwise and the last one fit laterally and also left enough room on the fuel tank wall for me to mount my 3 bank minn kota charger which is 12" long and 4" tall.  

 

I had to remove two batteries to mount my charger and it was hell getting them back in with the charger mounted but it did fit.. barely lol.

[Hattrick]

Awesome news.... not really.  I took my new Renegade out yesterday for the first time to start an hour long break in session. She ran perfectly smooth the entire hour then all of the sudden the 90hp Merc started acting like my old 2 stroke.  Running rough and sputtering RPM.   I made it a whole 1 hour with the mercury before I had to shut her down and trolled on the Ultrex 2 hours to the boat ramp. Thank God I had the 36V cause I wouldn't have made it otherwise.  The batteries were about 30% when I finally got home.  As for what she gave me when she was running smooth.  4 blade spitfire was only getting 40mph max at 5100-5200RPM.  Could only trim up a little before she would start porpoising on the water.  Common complaint I've heard from a bunch of other Renegade owners.  Probably a couple weeks atleast till I get the boat back and start worrying about tweaking anything.

 

If it wasn't for bad luck, I'd have no luck at all. 

[Further North]

That's not good...and the batteries don't sound great.  You should be able to run them pretty much all day and still have half you capacity or better left.

 

On that day above where I had to make it back to camp on my Terrova, I still had plenty of battery left.

[Hattrick]

Well they were at 12.1V when I got home.  I don't know... she ran almost 2.5 hours of 8-10 speed.  I may have had another hour at best just based off Ultrex amp draw and amp hour on the batteries.

I can't tell you where mine are usually when I get home, but I've run them all day, two days in a row without a charge.

 

Seemed weird to me.

[Jibber82]

Finally after almost 3 long months she's home. Too bad the dealership couldn't register it. Will have to wait a few days for the maiden voyage.

Sorry to hear about that Hattrick, I hope your dealer takes good care of you since that definitely shouldn't happen. As far as the porpoising goes, I recall during my break in if I didn't trim up my outboard how the boat wanted me to it would porpoise a little, but I've learned how to do it so it doesn't happen. I think you will just have to feel it out and then you won't have any more issues. For me I have to do it slowly, I can't just hold my trim button until its at the sweetspot cause if I do it too fast I sometimes get a little porpoising. I edge it up a little at a time until I'm right where I want to be and it works. Best of luck to you.
