@Temporarily Offline Ham Radio
They are packing the power up NICE and DENSE inside of this battery, what I found out is that this battery's low voltage cut-off is at 9.2V instead of the typical 10V that we've been used to for the past couple of years. They are packing a lot of energy into a very small space.

@Solar Power Edge
It looks pretty large, but a 300Ah (280Ah) battery looks a bit small size and indeed it is smaller than you would expect. And, that's why they're calling it a mini battery. Anyway, the battery pretty much has the capacity, the answer is it ran that heater for over 6.5 hours straight!
