I found, what appears to be a excerpt from TE-13.

Should vs shall seem to make these optional.

Interesting

Final Decision!

Well, after reviewing about 26 different lithium battery suppliers and based on information here and Facebook Jon boat forums, I finally decided to purchase from Amped Outdoors.

They seem like a solid company, their warranty process appears reasonably and customer support were responsive to my questions.

Also purchased the lithium battery charger they recommended. Felt that was a reasonable thing to do given the investment in this battery.

Expensive? Yes, but worth it to me having to lift a battery under 30 lbs. verses 70 lbs and if it lady’s as advertised then it’s about what I would pay in the long run for two (2) new 110 amp AGM batteries.

Decided to go with a plug instead of terminal connectors. Plan on using Loctite blue 252 on the terminal bolts and adding slippage lines as a visual installation to make sure they haven’t loosened up.

Will post some pictures of the battery installation when completed and performance after a few test runs on the water!

Received Amped Outdoors 100Ah battery and charger today!

Very happy with the weight! I can’t believe I can lift a 100Ah battery with two fingers waist high!

23lb 100Ah deep cycle lithium battery! The AGM I was considering weighed 70lb! Nice to have a 47lb weight savings in my boat!

Battery and charger came very well packaged!

Currently working on wiring the plug connector.

23 lb 100-Ah -- wow! That is 44 lbs lighter than my 105 Ah AGM battery. I'm jealous.

Thanks for the thorough comparison of options. I don't know what drives the current pricing (no pun intended) but hope it migrates down by the time I need a new battery.

What a great thread!

Any updates crannman?

Do you like how it performs? Any issues with charging?

I am currently looking at a new battery and charger setup for my new (to me) Lund C14. It will be an all-new setup and want to do it right the first time!

Thank you kindly!

I run lithium's for my motors and electronics, the 12 volt batteries running the fish finder and other steering and lifting shows input to the Solex10 as being 13.1 volts. Dakota lithium guarantees their batteries for 11 years and they include a charger made for their LiFePo4 batteries. At half the weight of lead acid types and twice the life, worth the extra cost. Keep in mind AGM's and lead acid should never be discharged past 50% capacity, it damages the battery shortening the life. LiFePO4's depending on whom you talk to can run to %80 0r %90 discharge with no damage and the voltage remains a constant 13.1. When I switched everything improved.

Excellent, thank you CRS!

Ill look into the Dakotas. I really only need one battery for now for the trolling motor. Once I settle on a FF/GPS, I may get another battery if it needs it.

There are no Q C standards for Lithium batteries . with or with out B M S . So BMS ....CONSTANTLY ... remain energized even with no loads turned on. So some time later your battery is run down. That is now a known fact with some brands. Chinese standards rule. With almost every brand.

China controls 80 % of LIFE production. No body controls China in battery standards. USA companies want the cheapest cost. Boat friend has 2 of 6 new 100 amp units dead on arrival.

It’ll be 2 years March 2023 and my Amped battery has been working great! Been using it with my 65 lb thrust trolling motors and have had plenty of power left at the end of the day. Really appreciate the light weight.

Lithium Ion ....IS NOT the same safety as a LIFEPO4 battery.

Any company can call their battery a LIFEPO4. And sell it with a massive profit.

In February, my neighbor was charging his new Lithium batteries for the initial charge for a solar system that he had just installed. He went outside to do something in his shed, and saw a shadow out of the corner of his eye. It was a plume of black smoke coming from his house. I happened to be driving by right then and I jumped out to help, but there was nothing we could do. Within 5 minutes his house was engulfed in flames. The above picture is real. It was crazy. Total loss. At least he and his dog got out alive.

NEVER charge batteries of any kind in the house is what the fire Marshal said, not lithium and not even flooded lead, because of hydrogen gas that they produce that can explode. The lithium batteries he had were SUPPOSED to be safe. I am now curious, and will ask him if they were LifeP04 or some other kind of lithium battery.

Either way, charge them outside.

To anyone considering Dakota Lithium, beware of the fine print in their warranty.....you must have the receipt in hand......my buddy had two out of three fail and they offered no help because he didn't have his receipt.....I saw that Amped Outdoors will go by the manufacture date if the receipt is not available so that is something to keep in mind

Either way, CHARGE them outside and NOT in beloved boat, CHEAP OR EXPENSIVE BOAT!

This is a classic example of what can happen when a mistake is made !! Lipo's are SAFE....but you cannot make a mistake, if you do..it happens so fast your out of luck !! In the above case, the wrong charger was probably used, been around Lipos for many years, to go up that fast the wrong charger or setting was used to try to charge the battery. Cant blame the battery for human error, but we need to keep in mind, that any mistake made can be instant disaster !!! No worning, just boom !! They burn so hot and so fast you cant react fast enough !! Unfortunately there are way to many folks out there using these type batteries that always think " that wont happen to me"....!!
