I have seen many good deals on various Lithium batteries and it is obvious to me that the prices are starting to drop again. The price drops are so dramatic from 4 years ago that I am working to convert my RV to support AGM & Lithiums.
There are so many brands, sizes, and capacity specification. I have seen several Will Prowes videos, while entertaining they don't leave me with answers. He has to balance his critiques and he is only focus on the battery(s) of the day.
I am looking to open up the entire spectrum based on what is good to buy? I don't acre to know if Battery A has bad solder, or if Battery B has a Temp sensor too close to a cell etc.
Assumptions
1. There is no specific capacity requirement, rather the most capacity possible to fit in the space of two Group 31 batteries or approximately in a area that is 20" X 20" and maybe 9.5" tall
2. Battery must have BMS with at least Low / High Temp cutoff
3. We are looking for value; so listing the most expensive battery possible is a nice to know for comparison. Name brand batteries are nice but name with no value is not the goal of this thread
4. Battery should have at least a 5 year warranty, and a method to actually contact someone if there is an issue.
To summarize and provide more context, in the last few weeks.....
* I have seen Lithium 100ahs for as low $150 with a number under $250
* I have seen Lithium 130ahs or 280 ahs in the $200 - $300 range
* Last night I saw 300ah that was only 15.2" wide and 1" of that were with handles. It was in the $500 range. I will post that battery as a starting point for others to validate specifications with the Mfg / Brand or find other Batteries that may be of more value.
Disclaimer: I have limited knowledge of Lithiums as it relates to RV, but it seems the battery I am listed may be part of a new normal, increased from 280 ahs to 300ahs and reduction in footprint.

All thoughts welcome.
