How do you charge that battery?

Why is everyone worried about hiding their batteries, if you have a homemade lamp on your bike that's enough for people to turn their heads!

water bottle area, and a couple of twist ties, or you could build something kinda like in my instructable.

i have a bulky 7ah batt. were or how could i hide it or disguise it.
you could just put it on a rack that goes over the back tire, its not disguised but it works.
Hide it in an old bottle and place it in your bottle holder.

i made a halogen flashlight with a 12v 60wat headlight bulb, its super bright, im running on 14.4v too so i get a boost

relly it dosent overheat im thinking about using a 12v 60w

i have a special car headlight bulb that is designed for low heat, when i first built it i used a plasic cup for a reflector just for proof of concept and it warped that but i have a aluminum reflector now so it is not a problem.

i bought the battery in a simple electronics house, and charge it with a small wireless 12v phone charger.....

Very nice! I have a recumbent bicycle with 36V electric assist, but no lights because the commercial market is too narrow. My plan was to mount three lights, one pointing straight ahead and the other two at angles to the side. I think I'll build three of these and hook them up to the 36V.
Cool man! I´m brazilian too. Nice idea, this lamp is more strong than led lights, but it requires more power. You need to tell how much time this kind of battery can handle the lamp on. And you need to paint this wall hehehe. Bye

hehehe i waste all my money with a light, and i dont have more money for the wall paint :D this lamp consumes a large AH, aprox. 1.67Ah, then with this sealed 2,3A battery the lifetime is aprox 1.3 hour. i have a commercial cateye led light too, and i use that in a easy ways, and i use the halogen for the downhills or technical ways. if you have batteries with equal or more than a 4000mah its the ideal lifetime... about a 2 hours lifetime im making a secundary light with a 5w and 150.000 mcd led, to use combined with a halogen to make a longer lifetime battery;; thx, Tyrone
