I am building a battery for my home made bike light. I have the light figured out but not the battery. I know that the voltage is additive. e.g. 10 1.2 volt batteries in series will give me 12 volts.
Is the amperage additive as well. Will 10 4,000 milliamp batteries give me 40 amps? Or is it 4 amps?
To get run time do I multiply volts x amps and divide by watts??
Lastly, how do I connect a homemade to a charger?
