Jamie, do-it-yourself repurposing of Nissan batteries by guys with lots of electrical knowledge and experience does not seem that uncommon, so maybe something you may want to look at also.

A friend and I were looking at option of buying Nissan battery modules to assemble a 48-Volt battery, around 10kWh in capacity, and it came out to around $200 per kWh for the used modules. To that you have to add cost of battery management and all connection hardware to connect a bunch of modules in combination of series and parallel.

There is risk involve though. If modules are old they may not perform well, and if newer but from a wrecked car they could have damage. Regardless, it’s an idea we are still thinking about in combination with 48-Volt inverter/charger.

The power unit in your post, if accurate that it’s only 700 Wh, seems pretty large for what’s no more energy than a common RV battery at roughly 50% discharge. I’m not sure what you get beyond installing an AGM in the trailer and using a small inverter. I suppose portability is a plus, so when done camping it can be taken inside house. Or at campground you can move unit away from RV to power devices. Not something I personally find very useful for our kind of camping.
