I was assuming that the question about the 5000mah battery was not serious...but in case it was...here are a couple pics of that battery (from one of my multirotors)...lined up with some mods...
From left to right:
Seigeli 150w; Ham 1591; battery; ipv4; and Hammond 1590b; Hammond 1590g.
So to answer the question: since the beta box is smaller than all of these - no way.
Think they are using an 850-900 mah batt.
I'm the guy with the dead screen.....protovapor has great customer service...
Went the same temp route with the clear hammond....here's a vid of messing with software...

Thats not a good sign. I had heard 1 other guy had a good board but the screen was bad. He installed it and was able to use mod without screen till protovapor sent him a new chip/screen.[/QUOTE]
