This might be a stupid question. But how much current can you safely draw from a AAA battery.
I am currently powering my project from a worktop power supply and it draws at 5V 0.45A during normal operations and peaks to 0.7A. Now I need to make it portable and looking for the right battery. I need to keep my project as compact and light weight as possible. I was thinking of using four AAA batteries or suitable Li-ions to power it on the go. The max duration I expect is 1hr but I will be satisfied with 45 mins.
If you have any other suggestion of powering the project please help me out.
