Lithium Battery

Has anyone tried this?

Second is cost. Unless you really need the power for the cost of the battery and a charger you could most likely replace the flooded battery 6 to 8 times. If the standard battery lasts only 2 years that's 12 - 16 years worth of batteries.

I just had to replace my converter and it was a standard one $300
I can only imaging that one for a lithium would be in the $500 range.

This should work to charge it
I'm more looking for the amp hours. I have to run the generator so my inverter charges the batteries to peak about every 2 hours when watching TV. I don't use the converter. It's been removed. I was thinking with a 100 amp hour battery I wouldn't have to charge as often.

First, you'd need to know the total amp draw on the battery. It's not just the TV to consider, but the few lights you're using, the parasitic drain that the trailer has, the refrigerator operation and then there's also the inverter/charger "intrinsic power consumption" to run its cooling fans, monitoring circuits, power loss through the transformers, etc.

To me, maybe not to you, but I'm not about to get up every 2 hours to crank a generator to "charge a battery to peak" only to keep draining it to run back outside again before bed to run it for another hour..... I'd want a battery system that is capable of powering my evening consumption without any work on my part and I'll run the generator for as long as it takes "tomorrow"....

I don't want to over think it. Not necessary. I've been using the same setup for years so I know how long it takes to drain the batteries to 25% and recharge to 100%. As far as stating the generator it's built in and I can start it with my toe while reclined lol.

The question is simply has anyone used Lithium batteries. I presume that with a 100 amp hour battery bank I'd at least double my inverter time. Just wondering if I'd double my charge time as well. And what's the true life span of the battery? With proper care I can make a acid battery last 8 years. And the fridge is always on gas. I don't run it on AC unless I'm plugged in which is rare.

Just a couple of observations on this post. If you are draining your battery to 25% you're killing it and shortening it's life every time you do it. A lead acid battery should not be drained below 50%. An 8 yr lifespan on a flooded battery? I'd like to know what brand that is.

ALL of the appliances (other than the stove/oven) require 12 vdc to operate the controller while operating on LP gas ar on 110 vac.

Two golf cart batteries will give you at least 100 usable amp hours at a much cheaper price.
