After detailing, all the things you need to know and consider in creating your plan for adding Lithium batteries and increasing your inverter capability, in this thread, Where Do You Start for a Lithium Battery and Coach Electrical Upgrade?

I've decided to replace my 2--AGM batteries (replaced my original Flooded wet cell batteries) located in the standard step located battery boxes found in Leisure Travel Vans. My top criteria for selecting a Lithium battery was to get the most power capacity per cubic inch of my step located battery box. I wanted a smart battery, that could protect itself if I did something wrong in using or maintaining it. I wanted a battery that had a heater or an easy way to put it in storage mode for the below freezing days we experience here in South Carolina. Most of all I wanted a battery that I don't have to worry about, as I do now!
I chose the Lithionics 315ah Battery (GTX12V315A-E2107-CS200) for my step batteries replacement. The Lithonics 12v315GTX is a single large 315ah battery that certainly maximizes the amp hour per cubic inch capacity of a Leisure step box (see picture of one in a 2020 Leisure Unity step box). It nearly fills the step box space, giving me the ability to safely use 90% of the 315ah, that's about 285ah of usable power. This nearly triples the amount of battery power I have now!
Couple this with the fact that the Lithonics battery has up to 250a continous charge/discharge current and a higher discharge surge rate, meaning it can handle heavy load surges like when the air conditioner compressor turns on. It can supply the entire coach operations once I add a 3000w Inverter and a Micro-Air EasyStart to the air conditioner (which I have already done, post #14, https://sprinter-source.com/forums/index.php?threads/73240/#po). Remarkable, just what I was looking for!
The Lithionics battery also has an Advanced Smart Internal Battery Monitoring System, with Bluetooth connectivity (Bluetooth® App Support) that provides a NeverDie Power Reserve, High and Low Voltage Cutoff, High and Low Temperature Cutoff, and Short Circuit Protection. So this Lithionics battery can take care of itself, certainly adding to the overall life of the battery. The Lithionics warranty says, "The battery will be free from manufacturing defects for a period of 5 years. Also, when used correctly, Lithionics Battery warrants the battery to deliver a minimum of 2,000 cycles at full depth-of-discharge or up to 6,000 cycles." Do the math, that’s over 16 years if you use your Lithionics battery everyday of the year, which I don't! Certainly, this Lithionics battery will be the last house battery I buy for my Leisure ownership and very probably the last for the Life of my Unity!
Lastly, the Lithionics battery can take care of itself in freezing temperatures! It has an Internal Battery Heater that uses 1a/hour to maintain the Battery temperature between 35-40° F, so it can continue to safely charge. I like this because when I park my Leisure for the winter I rely on my solar system to maintain my batteries and we do have periods of temperatures below freezing where I live in South Carolina. So the Lithionics internal heater is something my solar system can easily support and still keep my batteries fully charged. With the Lithionics Battery switch on the battery itself, I also have the option to simply turn it on or off. This certainly gives me a second storage option as well as the switch makes it very easy to work on my Leisure. Sometimes I need to have the 12vdc power to be completely off, which in the past required me to disconnect the batteries. Now I can just press the on/off switch on the battery itself to shut off the house battery power! LOVE IT!
Another step box batteries replacement option is the newly released Lithionics 125ah (12V125A-G31-5CND) direct replacement battery for your Flooded Wet Cell or AGM deep cycle batteries. It is 25% smaller, only weighs 33lbs, and is priced competitively with manufacturers of small 100ah Lithium batteries. This new Lithionics 125ah Group 31 sized Lithium battery is an excellent, extra capacity battery choice replacing your current dual 6v batteries, given all the features as follows:
-250 amp hours (225 ah usable power) in the same space as your old step located batteries, which allows for 90% usage (10%SOC),
so more amp hours available to support the entire coach.
-25% smaller than a Flooded Wet Cell or AGM deep cycle battery, and only weighs 33lbs each.
-Fits perfectly in your step located battery box with no modifications required (see the picture where a Leisure Wonder owner installed them).
-Convenient On-off LED control switch right on the top face of the Battery.
-Remote control switch port
-Bluetooth APP and Diagnostics
-Excellent Bluetooth Connectivity Internal Battery Monitor, so no need for extra external battery monitors.
-Engine cranking capabilities....works with a battery boost switch.
-The NeverDie Power Reserve, High and Low Voltage Cutoff, High and Low Temperature Cutoff, Short Circuit Protection,
Bluetooth® App Support
-Marine Grade Plastic Case
Lithionics is working on adding an optional Heater kit and a new remote hard-wired state of charger meter/display. So this new Lithionics 12V125A-G31-5CND has nearly all the features of the more expensive 315ah battery, but at a third of the price. Contact Lithionics for more information or to ask about the Special Pricing for Leisure owners. If your top criteria of a battery is to get the most power capacity per cubic inch of your step located battery box, then look to Lithionics Lithium batteries to deliver!
My new Lithionics 315ah (GTX12V315A-E2107-CS200) battery is being delivered tomorrow so it's time for me to get on with my own installation of a Lithionics Premium Lithium Battery, Xantrex Freedom XC Pro 3000w Inverter with Bluetooth Remote Control Panel, Sterling 30a DC-DC charger, and adding 2-100w solar panels to my current 200w solar power system.
