A question

Last summer was the last time my bike ran. I'm gonna try now soon to get her to run (havent tried since) and i'd like to get some opinions. That day, I went out, and my battery ws fully drained, thanks to a light me and my friend had foolishly installed for some really corny coolness. So I got a boost off my dads truck. She ran for a bit, shut off, another boost, ran out the road, got back, she was fine. Went about another 10km and I cant remember, either she shut off or i shut her off, but wouldn't start up, tried jumping and numerous kicks. She'd usually start first kick on a warm engine and charged battery. So i got a boost again (bad, i know) and off I went, drove for about 20-30min, had an accident, and here I am. Was all of this caused by a realllllly low battery, or is my charging system screwed? Sorry for the long rant.

you would have to check the voltage at the battery it should be near 14.5 at 3000 rpm
