Epcom Battery

[iRondo]

I've run across a battery I've never heard of before. Epcom is the company. They have bases in Florida and in El Paso, Tx. I'm in Mexico and it seems like this is really the only option available to me, but I would like to know if anyone has any knowledge about these batteries.
The website doesn't give chemistry, type of cells, BMS protection, or even dimensions. I searched Youtube and was hoping for a teardown video from Will, but came up empty
