Automatic Battery Switching

[natewaz]

Hi I am currently trying to use two batteries (individually) operating at about 1 volts to power my circuit, the trick I need to figure out is how to switch between batteries when the first battery drops below . 7 volts so the second battery which is at 1 volt can now power the circuit.

Thanks,

Nathan

At those voltages use relays

Any relay in particular, could you post a link?

Thise two batteries are only source of power? Batteries are NiMh 1,2V?

I know for reed relay at 3V but I dont know any relay on 1V.
