Hi aarg, sorry for the low quality circuit picture, I was just trying to give a general idea of what the circuit looks like, but the software I used to draw it is quite limited. The mini usb's are connected to the battery supply, along with the rest of the components so the LED strips are powered by the battery via a mini usb connection, they just don't turn on unless the two points that I mentioned are closed, which is where the relay comes in.
Thanks for the input, I don't have another battery with me at the moment to test with, and I'm very inexperienced when it comes to batteries in general so I'm just looking for a more experienced opinion that I can go with. I was thinking of looking at replacing the battery with a 12V pack, do you think it would be sufficient?
