Crazy Idea with Cellphone Batteries. Need an Experts input
So my thought was "what if I put TWO batteries in there?" Crazy, right? I mean, I can't actually fit two batteries in my cell phone, but what if I could find a way to run wires from the outside of my phone to the battery on the inside, augmenting that battery?
The problem I have is that I'm not sure if this will result in extended battery life, or an explosion. I know that Li-Ion batteries are not like your normal AAs. And I know that to keep the voltage right, I'd have to wire them in parallel. But if I wire them in parallel, without some sort of circuit in front of both batteries, will that be safe?
I think that if there was a circuit in front of the two batteries hooked up in parallel things would be fine. But if I just hook to separate batteries in parallel, each meant for my cell phone, then each battery will have the circuit protecting it, but not the two in parallel, and that might be dangerous.
So anyway, if anyone out there has any idea on how safe this is or isn't, I'd appreciate their input!
