A LiFePO4 drop in replacement with a good price and prismatic cells.

Larry at Starlight Solar pointed me at this new Lithium Ion battery product by Life Blue

These are drop in replacements which is fantastic.

Unlike other drop in they have full instrumentation so you know how the batteries are working internally. Even better the instrumentation is blue tooth so no wiring and a soft interface that can easily be upgraded.

These are built with large prismatic cells so instead of hundreds of little cylindrical batteries packed in a box you just have a few large cells that
can be balanced.

And the best part is that the 300AH battery is $8.26 an amp hour which is about as cheap as it gets.

I plan on installing 3 or 4 this fall when I'm back in Yuma.

I have no affiliation and receive no compensation with Starlightsolar or LifeBlue I just thought this was an interesting new product.

Looks new. Interesting. Does the bluetooth only connect via the bluetooth device or is it internet enabled?
The problem is how long the company be around? There have been others that have come and gone. That's why I went with GBS cells. They have been around a while and have a track record. Also, not that much cheaper than my 600 Ah GBS setup.
Personally I like having separate BMS from the batteries themselves. If any one component has a problem I can bypass it to get back up and running. But that is me. Some will def want a drop in component. I still think you need to know what you are doing to properly set up the charge profiles from the charge devices like solar and AC converter.

They sound great. But best I can tell they are made and assembled in China. I know many don't care but I'd pay more for a battery I have confidence in and China at this point in time does not inspire that.

Interesting. Their website states "drop in replacement" means it is a complete package sealed in a standard battery case. Does it also mean that the coach electrical system and PV system will connect with no modifications and charge and discharge?

yes, it means that. it is 12v battery, just like a 12v flooded or agm battery you would buy, except it's lithium.

i started with making out of 3.2v cells, chinese "calb", no issues in nearly 3 years.

there are a number of major lithium factories in china. calb is the largest. another well known brand is thundersky /winston. i have cells from them too. i don't know much about this one discussed above. to my knowledge, those mass li factories make cells only, they don't sell complete batteries. for this particular battery, i guess the cells are still from one of biggies, wrapped with their own bms, display, etc...
