Shut up and Fish. So roughly 2 k for everything to get me taking care of ?

$2150.00 cash price, local pickup. Additional cost if shipped.

Take a look at our EG4 Lithiums. They are 12V 100 Ah in a group 24 series, 22 pounds apiece, and have Bluetooth monitoring from your cell phone via the app download.
$550.00 each.
I recommend going with three 12V 100 Ah for your trolling motor and a NOCO Lithium battery charger.

Noco GENPRO10X4
Battery Charger; For 12 Volt Batteries; 4 Bank Onboard Charger/ 10 Amp Per Bank; 120 To 240 Volt AC/ 50 To 60 Hz; 40 Amp Charging Current; 11.4 Inch Length x 2.8 Inch Width x 9.1 Inch Height
$499.00

Why do you need a lithium battery charger?

Many Boaters and RVers have turned to lithium batteries advanced technology to support their power needs for many reasons. They have many benefits compared with traditional deep-cycle lead-acid batteries. They weigh less, provide more power, have a longer lifespan, are maintenance-free, and are more environmentally friendly. You’ll also get a faster charge than with lead-acid batteries.
With all these benefits, suddenly, a lithium battery charger becomes essential. Let’s find out why!
What Is a Lithium Battery Charger?
Like the lead-acid charging system, a lithium battery charger is a voltage-limiting device that aids in batteries’ safe charging. But the similarities pretty much stop there.
The two battery types have different chemistry for creating energy, so they need corresponding chargers to meet those chemistry needs. Lithium battery chargers can safely charge lithium batteries at a much higher voltage (translation: faster charging!). At the same time, they give the chemical interactions within a longer lifespan (translation: fewer replacement batteries).
Can You Charge a Lithium Battery with a Regular Charger?
Can you? Absolutely. Should you? That’s a question that deserves a more detailed answer.
If you used a regular charger, the lithium battery would charge. However, it would charge far more slowly. Lead-acid chargers use a lower voltage by design. If they didn’t limit voltage significantly, batteries would overheat, leading to fire or even an explosion! But there’s more.
When considering lead-acid vs. lithium chargers, identify the voltage range of the two batteries. A resting lead-acid battery will reach full charge at 12.6V-12.8V. A resting lithium battery will not be fully charged until it reaches 13.3V-13.4V.
Because lead-acid chargers must use a lower voltage to charge batteries, they can only fill around 80% of a lithium battery, which is not good for the battery (nor for the RVer needing power!). It stresses lithium chemistry and reduces the battery’s lifespan.
So, not only will you need many more hours of charging time with a regular lead-acid charger, but you’ll also be “stressing” your lithium batteries in the process. These issues challenge two of the best benefits of lithium batteries!
Lithium battery chargers will charge the corresponding batteries five times faster than a lead-acid charger. If that’s not reason enough to support this upgrade, let’s consider a few other factors.
The voltage of lead-acid deep-cycle batteries continuously falls as they discharge as well as with increased load.
That’s not true of lithium-ion batteries, which can provide peak power, as well as constant voltage no matter the load. A lithium battery charger aids the battery’s efficiency and storage process.
As mentioned previously, the voltage range of lead-acid vs. lithium batteries matters. Because a lead-acid battery is full at 12.7V-12.8V, most lead-acid chargers won’t start bulk charging again until the battery’s charge drops below 12.5V-12.7V. So, if you use a lead-acid charger for your lithium battery, you’ll have to use almost all of your lithium battery’s stored energy before a lead-acid charger starts charging it again.
What does this look like to the average Boater and RVer? Let’s use an example related to solar charging to illustrate.
Even if the sun is shining brightly, a lead-acid solar charge controller won’t start charging a lithium battery until the charge has dropped sufficiently. It will remain in float charge, and you’ll lose the benefit of the sun’s power to recharge your batteries during daylight hours!
This is just one of many examples showing you need a lithium battery charger if you use lithium batteries.

I'm ready!!!

Those lithiums are nice, but dang….$1700+ out the door for three batteries?! I have to take up a cheaper hobby!,

No disrespect to you, SU&F, I know that’s just what they cost.
