Greetings,
Anybody have any suggestions for a battery over-discharge protection circuit?
I have been using home built NiMH battery packs in some of my projects. (for instance my most recent uses 10 C cells). However, after doing some research, I've learned that these packs (also LiPO) packs, can run into trouble if they become over discharged.
I think I'd like to learn how to incorporate a circuit design that would not allow itself to operate if the terminal voltage of the battery dropped below a certain point (for instance 10V for the 10 cell NiMH pack.)
I've done some searching around and have come across a few designs, just curious if you folks had some insight in the area.
My most recent project did incorporate a six LED battery meter using an LM3914 chip which I calibrated such that the last LED is lit when the battery is at 10V, so I know not to operate the gizmo beyond that point, but I'd like to develop an actual under-voltage lockout.
Thanks for any suggestions!
