Here you go. I've been using these batteries for over 2 1/2 year and have been rock solid.Other members have been using them also with the same results.
If you have a Stealth charger rip it out and replace it with one one of the ones listed. Lithium doesn't like to be charged in series like the stealth does.
Relion Lithium batteries Trolling motor 24V setup (2) 75 or 80 ah for 36v setup (3) 50ah and for starting a 80ah or a 100 ah which I recommend.

I still have what Frank put on the boat 6 years ago.
Odysseus batts and Stealth charger. Flawless performance.
Others have moved to Deka AGM batts and Powermania charger.
This place has good price and ships for free.

Lithium is expensive.

Installing Relion batteries for new trolling motor and starting battery.  Speaking with their sales person he indicated the best deal is the 12v 100ah battery.  Also, from July 1 to July 7, 2019 there is a 10% discount on all purchases.

Per our discussion, and cost/value, I am going to be using 2 12v 100ah batteries for the trolling motor (RB100) and 1 12v 100h High Performance (RB100-HP).

Additionally, they work with Pro Charging Systems for their chargers - by doing so they will program the charger with the Relion charging parameters.

That's the charger I;m currently using now the Duo Pro flashed for the Lithium's. It's working great. But other chargers will work very well like I stated above. You won't be disappointed with that charger other than how heavy it is! Good luck holding it up to mount. Your going to need two people. You'll be very happy with those batteries and there performance. It's a investment but worth it .

FLandME

Thank you.  I noticed the Duo Pro 3 bank weighs 22 pounds.  Certainly takes up some of the weight savings gained on the Li batteries.  Is the changeout for the my Odyssey batteries (currently 2 for just starting and peripherals) as simple as changing the connections?  

FlatsBoy

Yes they are 12 volt batteries positive & negative connections.

FLandME

Thank you.

FLandME

All installed.  Everything works great.  Love the batteries and the charger.

FlatsBoy

Glad it worked out any questions feel free to call me about charging them.
I would charge them up if you didn't already before using them. Then charge them overnight after each use and unplug next morning no need to keep them on charge they won't discharge like AGM or lead acid.
Awesome!

FlatsBoy, just curious why you switch from power mania to the Dual pro. Although both are good chargers the Dual Pro is larger and heavier.

FlatsBoy

I did not switch. The new boat was rigged and came from Relion as a package with the Duo Pro charger flashed with the Lithium profile.
As far a Powermania I did have two failures and went with the pro mariner elite charger which was flawless. If I had a choice I would of put the Pro Mariner Elite in.

Hello Phil, did as you suggested and everything seems to be working great.  One issue did arise.  My new Simrad NSS Evo3 had a warning come up a few times that said “high voltage” greater than 18 volts.  

I measured the batteries after giving them a full charge and they were 13.5 for the house battery, and 13.67 and 13.71 for the trolling batteries.  Is that a problem?

As always, thanks.  

FlatsBoy

I've never seen a high voltage like your experiencing. Did you have the Simrad on while charging when did you see this?
Let them charge use them and them a few times. They will read high once you take them right off the charger. Let them settle overnight then measure.

FLandME

Hello Phil, sorry for my delayed response, was in ME for a bit and now back to the warm FL weather.  

The warning light came on during use on the water.  I did not have the Simrad on during charging and consequently did not see any warning during that time.  

I will I’ll get the boat out on the water later this week and see if it comes on again.  

As always, thanks
