Duracell power pack LIFEPO alternative

[Hera]

Hello all.

Im gonna get the Pedal-A-watt system to charge my gadgets, computer and AA,AAA and 9v batteries while camping on the forest this winter.

For who does not know what is this is just a rack with a motor that creates energy from pedalling.

Im not very experienced on electronics and battery systems but from what i know, the power that i would create pedalling has to be stored in a battery system before charging anything. My question now is: Can i create a similar system to the duracell power pack, what means a battery system than transforms energy so you can plug any electronic device, in my case battery charges and other things to charge, with a LIFEPO battery? Well. Im sure i can, but does anyone nkow what would be a good way to do it?

I was planning on getting a 48v 10ah battery to use in the future with a mac motor attached to my bike. Would this battery be able to do the job? how?

what are the advantages of more or less volt batteries appart from off course more energy (that means miles/speed) considering that i want to use the battery as a power pack when stoping the travel ? Probably a stupid question to must of you but i really have no idea.

You need Rechargeable batteries..

But you know what, id love to see someone make an ebike with some Duracell 9 volt batteries

Does anybody know the c-rate of a duracell nine volt? and i can verify its easy to connect the nine volts in series, use the inbuilt connector (anyone know h many kiloamps these are rated for? I think they are plated with nickel at least ten thousandths of an inch thick so....)

im thinking of a homebuilt ef/plasma gun using around fifty, ninevolts in series and a tungsten filiment?

but seriusly get a ping

52 9 volt batteries in series ...

Better option:

1) cheap hub motor kit with a regen capable controller.
2) whatever cheap battery, lithium, SLA, or whatever..
3) dc-dc convertor to turn the bike battery into whatever you like, 5v, 12v, etc..

If I undersand what it is you want to do, you need at least a DC DC converter to go from 48v to 12v. Once at 12v there are various options for chargers to power stuff like the ipod and phone.

I've got no clue what voltage this pedal generator you like uses. The standard charger for a 48v lifepo4 battery would run on AC. I would think you'd want some A123 in whatever voltage the peadle thing uses.

If your Ebike was a direct drive motor, you could have a regen compatible controller, and just pedal the bike to eventually recharge the 48v 10 ah lifepo4 battery. You'd be pedaling all day though. At least 5-6 hours of pedaling to fill it, at 100w of pedaling effort.

It wouldn't take so long though, to replace the energy that went into an ipod. Why not just solar for charging small stuff?

a while before my computer fried, I found a youtube video of a british(?) guy who made an electric bike in his garage using about 36(?) rechargable d-cells to power it with a range of about 9 kms. Anyone see this video, and if so, could you post me a link? Thanx so much!

as far as powering an ipod, they have hand crank chargers for ipods on ebay for way less than $20.

I think he's after a hub dynamo, like this one http://www.nabendynamo.de/english/index.html

I helped a friend in the past with something similar. He toured across Australia and needed to charge his phone and bikelights.

The electronics are very simple and available off the shelf.
