Having realised that LiPo batteries are probably the best choice for my project, I've been doing some reading and have seen the dire warnings about overdischarging them. As such, I'm looking into building a low-voltage warning system into my existing circuit (which is based around a PICAXE-14M). As I've already made the circuit board, I'd like to be able to use as few external components as possible.
So here's what I want to happen:
Would appreciate some help on the circuit design to achieve this.
So here's what I want to happen:
- Battery voltage falls to 3V
- Output of warning circuit switches from low to high
- PICAXE interrupts on this output and stops driving loads (two high-power motors)
Would appreciate some help on the circuit design to achieve this.
