It's been sitting in my garage for about a week since I got it, hasn't been started at all since, When I got the car it was going great, Started first turn. I've had the lights on when I was cleaning up the bodywork as my garage lights are broken, Just want to know if you guys think it's the battery or something else,
Here's a video showing the dash when I try to start it:



All the lights work, radio turns on, fuel pump primes but, when I got to start it, It just makes a click noise and all the electrics turn off, a few minutes before I took the video, It was doing the same thing but, the engine was trying to start.

 

Charge the battery.

 

It's charging now, I'll post an update when it's done, I hope it's just the battery and nothing else.
