The battery spec on the diagram is outdated, sorry, my bad. It'll be powered by a 7.8v 2S lipo silicone-graphene 46wh battery first off, allowing provision for a more powerful cell later on. The circuit is only live for a few seconds at a time every few seconds, so the overall battery life will be short but will fulfil it's time requirements. It doesn't need to be running a .12ohm element either to be honest, as I'll be making it myself I can vary that somewhat, it just falls as easy to do @ .12 and gives me a baseline number to work to.
I'm sorry my description is so vague compared to the diagram, I needed starting point math as a parameter to work from. All my variables will ascend from that point if that makes any sence..
So.. you guys see this as a viable circuit, all be it over engineered? There's nothing dangerous (with the exception of the current battery's output limit)?
