I am keen to see if I can charge a lipo battery and power some basic electronics using the wind rather than solar.
Does anyone have any thoughts on what charger I should use. I am looking at, the following:
- Adafruit Universal USB / DC / Solar Lithium Ion/Polymer charger - bq24074 Australia
- USB / DC / Solar Lithium Ion/Polymer charger - v2 Australia
- SparkFun Sunny Buddy - MPPT Solar Charger Australia
I can have read the spec sheets to look at the differences between things like input voltages and charging rates of the lipo batteries in amps. I know I should be looking for a decently matched motor with low starting torque, so not too heavily geared.
Is there something fundamental that I am missing whereby these solar chargers will not work at all with the DC voltage generated from a 6-volt motor? It seems like the adafruit options would only work with a 6-volt motor, but that the more expensive Sparkfun MPPT option would open up the possibility of a 6-volt or 12-volt motor.
