Need electrical advice - dynamo light set with rechargeable batteries -> capacitor?
Hi, There's a cheap dynamo LED light set with rechargeable batteries here: http://www.energystead.com/wind-n-go-bicycle-light-kit/
An Amazon review reports it carries 4 AAA rechargeable batteries. Because this set will only get occasional use can I replace all four batteries with one hi-capacitance capacitor like this one: http://www.alliedelec.com/search/pro...5#tab=overview
to maintain a standlight effect?
The set is in the mail. If you need other specs let me know and I will post them.
A capacitor is not a battery replacement, but its appropriate for a standlight. But there are major differences.. a battery will to a large extent smooth voltage, a capacitor will just charge to the highest voltage that hits it, if diodes are involved.(and they would have to be to charge either one from an AC source like a dynamo.)
