Why use rechargable batteries?
How to recharge the batteries on the bike.
Why alkaline batteries?
When normal batteries go flat you have to replace them with new ones. If your a days ride from the nerest store then this is a great inconvience.
So rechargable batteries come into there own miles from nowwhere.
If you standardise on one size of batteries then you can have one set in use in the GPS/torch/tape machine etc the other set can be recharging
or ready for use if the first set needs recharging or fails.
Ok, the batteries can be recharged as the bike is running. This should be enough for most people.
The only exception would be someone who is stopped for a while.
Then you may want to recharge off the bike battery without running the engine.
I'll put up the circuit etc when I get around to it, but basicly I will use one LM317 regulator per battery
set for 1.5 volt 15 mA maximums.
Driven through power limiting resistor then a switch to select running off the battery or off the igition circuit.
Nicad batteries can have memory effects which decreases the apparent capacity of the batteries.
I think these may be the best choice of the current recharable types.
The only draw back is that there apears to be no avalible rechargers that run off a vehicle.
So I made my own simple design and constructed it.
