POWER UP FOR SPRING

[Bill Babler]

I was told long ago when charging your battery to leave the rear hatch open so gasses could escape, even with an on board charge system and to keep the bilge clean, always have. Another great point, love the information.   (Back to my old Water Patrol days.)

C4F also makes a great point in with all the advertising out there right now, It's nice to see all the testimonials on this thread of how well these Pro-Guide batteries have preformed for our forum members. 

Hands on performance by people you know is always the best medicine. 

Thanks all that have contributed, good stuff.

The ones I bought are $950.00 @ tax included. 

I will tell you Minn Kota has had a problem with Lithium power. 

Their trolling motors are very sensitive to a high charged battery, they have a protective device in the motor to prevent it from burning up from excess voltage. No problem with the AGM that comes in at 13.3v but for sure a problem with a lithium that is coming in at  13.7 or .8. 

I think Minn Kota suggests 12.8 as maximum voltage regardless if it is a 12/24/36. Size motor. 

 

I am running a 36v ulterra on my riverboat and built a LiFePo(lithium iron phosphate) battery for it. fully charged its at 40.8v with no issues.  I did find out the hard way that the low voltage shutoff was 25.6v😗

Are there issues with lithium cranking batteries?

Lithium are not designed for cranking. They are deep cycle Trolling motor. 

Any 50  plus amp charger will work.  They don't even make the one I have anymore. 

The Garmin are way to picky on power. Just shut off the warning. If it gets to 11.2 they drive you nuts. Your poor start is a different animal. 

Don't know why it would but you can add an additional battery to your boat functions to keep the cranked up. Mine is no problem all day with 4 graphs and a ProGuide series 31 110 AH.

There are according to Mercury.  However, I heard that the mother company, Brunswick is getting into lithiums.  I’m not sure what that means.

There are no issues with lithium cranking batteries as long as they are DESIGNED for cranking.  The BMS on a deep cycle would shut off for safety before allowing the amp draw a cranking battery has.

My rzr 800 has had a LiPo cranking battery in it since last summer.  It works great.

Good info Muddy. I would just about bet your high voltage feature on that Ulterra  is not working, and that may be a good thing. 

I know of at least 8 to 10 guys that have had issues and could not figure it out until they were told to depleted some charge, then it was right as rain. 

Wrench most likely knows the answer.

I will take luck any day!

If you're referring to issues with Lithium power cells, then I honestly don't.  I still have some stuff to learn...... but truthfully I'm not so sure that I even want to.  I'd prefer to just not get involved with them. 

I have seen the results of 2 total meltdowns so far, and I couldn't figure out the cause in either case.   

I'm nervous of things that I don't have a solid understanding of.

[Bill Babler]

Totally understand. Thanks Wrench.

my first lithium battery had an internal short and had a meltdown.  It was pretty bad.  the seller assured me that they have not had many issues with them so I let them warranty it out and so far so good.  Keep in mind that the battery that failed used LiPo cells, and the batteries @Bill Babler purchased are LiFePo which are exponentially safer.

The scary part on one of the meltdowns I inspected, was that even after the ground lead was cut free (or better yet....ripped loose in a panic).....the battery continued to smoke, sizzle and pop until finally something inside it burnt in two.    

To have that happen while out in the middle of the lake...

Yikes !   😯

mine internally shorted so it did the same thing.
