Hi everyone, I'm building a portable speaker, and I want to build a rechargeable battery pack for it, using 10x 2500mah nimh batteries.
I really don't know much about this, so I need someone to let me know if I've got things right.
I want the speaker to be usable whilst it is charging, and ideally the charge time would be about 10 hours.
From what I understand, all I need to do is connect the battery to a DC current, and limit it (with a single resistor?) to about 250ma, which should be safe for trickle charging. Is this literally all I need to do?
What should the input voltage be? Thanks.
