Electrical question

[kro]

If I have 6 x 1.2v batteries, and run them in series, I get 7.2v, that bit I understand. Each of these cells is 3500mah, so when in series, does the mah tally up, and become 6 x 3500?, or does it stay 3500?.

I'm making some lights for my mountain bike, and this is holding me up.

Thanks troops.

Batteries in series the volts add BUT the ampHours stay the same. regards Richard

Yuff. You need to put them in parallel for more amphours. You can do both, but then you'd need 36 cells !

Thanks troops, I appreciate the replies.

"Ohms Law" still works huh ! Electronics has changed nothing. Sort of like the Waitangi Treaty.

why not just purchase a recharcable 6v lead acid sealed /rechargable battery and strap to bike frame.. runs around 4.5AH less than $20

Be easier to handle too!

Some of the guys I ride with use them, and they are big, bulky, and square, and I was wanting to try something more streamlined. If I move to D size cells in NiMH, I get 7ah, so that's looking even better.

So instead of being the above and square they are round?

Or you could have done what i did and ran 4 10mm 10,000 mcd superbright leds. You can ramp up/down the current between 14-120mA for brightness. But the suckers take about 4v each.
