Good thinking!
Unfortunately charging a battery by a battery doubles the efficiency losses. Due to heat dissipation as a result of transition resistance, the losses while charging a battery amount to 20% depending on hardware and current.
Your proposal would reduce the overall charging efficiency to 60% which is a really demotivating number when you have to pedal the power into your pinetab yourself...
Quote:It sounds like, as dachalife suggested, you may want a little bit more self-crafted hardware to maintain that 5v at traffic lights and such. But this "feature" is going to be a pain for you, for sure.
You are right. It would involve a bufferdevice; i.e. an extra battery with the aforementioned setbacks...
