Details on the alternator? I know the rear climate control option gave me an upgraded one from the factory (150A vs 130A) but no idea what other options I have.
I've purchased a couple of alternators from these guys. The first, in our old 1998 Hundy LC., and the one I have now in Lexy.
My current one, I've had for over 7 years now. (quick... where's some wood to knock on!!!)
 
You should watch out with voltage boosters. I had one for a bit and it fried several aftermarket interior LED bubs, my license plate bults, and I think it may have also fried the digitizer in my PX6. If you have all name-brand electronics in your rig it might be fine, but the extra voltage can quickly kill cheaper electronics.

FWIW, my AGM battery works just as well running normal ~13.4 operating volts as it did running ~14.4 volts with a booster installed.

I bought the battery booster after reading that AGM batteries would benefit from a higher voltage charge. I too didn't really see any change. But for sure I'll be needing it with the lithium.
Also, when I first installed the voltage booster jumper in my fuse box, I put it in the wrong space and fried my ECU. A couple grand later, to fix it. It was a stupid mistake on my part not paying attention to where it actually plugged into.

That's a breath of relief about getting one! Thanks Hiluxforever!

I ran the VB in my 5th gen 4R for about 18 months, and the GM diode (VB didn't have one oriented correctly at the time) in my Tundra for 16 months (I'd assume it's still in it, and that would mean it has been living its best life for nearly 5 years now)
 
Yep its just a diode. But if you have any weaknesses in your electrical system, as mentioned above, it will expose them.

I've had that little diode on for about 3 years now, no issues... yet. Hopefully none will come up with the new LiPo battery either.
 
I was running a diode VB. Perhaps the more advanced one with a medium and high setting would have been better and kept from frying things. But, I've seen zero reduction in battery performance without the VB, including when it got to -10F for a week last year. The GX started right up, no problem.

By charging at a lower voltage you wouldn't necessarily see any difference in start up/cranking power, but the battery will never fully reach 100% SoC, and could reduce the battery lifespan. Realistically, I believe the number is somewhere around 80-85% SoC, so you're losing (depending on your battery size) 10-15Ah of usable capacity

Thanks - I checked my camper battery (which gets a constant ~13.3V of charge when plugged into shore power) and it was sitting at 13.0V. So, if anything over-charged. But, my GX was only at 12.5V - definitely under-charged. I'll throw the NoCo Genius on it for now but also get a Voltage Booster Pro that has a low-setting.

Most of my LEDs are slowly being swapped out for Diode Dynamics bulbs anyway, instead of Chinese crap.

I recently got an AGM battery and do not have the voltage booster, but have been diligently charging it overnight every 1-2 weeks. Have a genius 1, just got an onboard genius 2.

my gx does on average 5 drives less than 15 minutes each day, which I understand is not good for batteries anyways.

This is definitely another option, plenty of the 3rd gen Tacoma guys did this for years before an ECU tune with a voltage modification was available

What is your AGM battery in that you need to overnight charge?
Regarding usage, now that I'm trying retirement, I'll go days without ever starting my GX. The longest drives are to get my hair cut by my half brother (who's a Master Barber) and lives about 30 miles away. He cut's my hair for free, I buy him lunch and we catch up on family. I do that once a month with him, a couple days before my monthly Army drill.

I'll probably forget to do that, and I park the GX a ways from an outlet :). I do have a Genius 2 sitting in a box - along with a NoCo 120V male plug - to install on my tractor so it's ready to go when I need to run it at cold temperatures to move snow and wood. But, it's parked right next to an outlet.

I have the Costco interstate 24f AGM. When I plug it in, it's under 75% SOC (red pulsing light for Noco chargers), and it's above the next morning (pulsing green light).

edit: the Noco brand chargers can also do lithium batteries and should work for your application. I dont think LFP will have that much of a discharge just sitting for a few days so you should be good, from that perspective.

One thing to remember, that charger is basing SoC off of voltage, which is less accurate with an AGM (or even EFB) than a traditional battery as the voltage/SoC curve isn't quite the same; and SoC based on voltage is effectively useless on a LiFePO4 batteries

My NoCo chargers have a mode for AGM and typical lead-acid.

Shore power, all hotel services including ships power have to be received from shore before the Ships Service Turbo Generators (SSTG's) can be shutdown and you can enter the ship is now "Cold Iron" into the ships Engineering Log. Syncing the power can be interesting to say the least, if you are off by even a little bit things get rather interesting when you even briefly turn an electrical generator into a 3 phase electric motor 🤣

I learned with my 2nd gen Taco to stay clear of those Chinese made POS LED's. I have replaced my OEM on the GX with Diode Dynamics out of the gate. 4K as I don't want the sterile hospital environment many use with the 6K in my Luxury vehicle, nor kill my night vision. With the exception of the rear lights above the attic rack you can never have too much light back there IME. My last ones to replace were the reverse lights I went with the DD XPR the brightest ones they sell. Spendy but were worth every penny. I may replace my running board lights with DD blue yet, just not sure if it will be too pimpish or not LOL.

Once again I like how you think 🍻

The hard lesson of buying once and crying once! DD lights are based here in MO and make many of the lights here as well, which is always a plus :).

I had no idea about the history of "Cold Iron", but good to know! I always thought it was weird that RVers use "shore power" despite being land based.
