Gday,
Just a question for those who have made their own lights using luxeons
or cree powerleds..
(or other nerdy types who like soldering stuff)
I built up a light using 3 cree xr-e power leds. At first i just got 4
AA 2500mah rechargeables and put them in a battery case from jaycar.
The case meant the batteries were wired in series. So i ended up with
4.8v and 2500mah.
The light was incredibly bright, (much more so than my 12watt marwi
nightpro halogen) but it'd last about 10 minutes before starting to
dim
Since then i got some c size 3000mah batteries with solder tabs and
wired them in parallel. Long run times now, but its about as bright as
a standard 30$ led light and useless for the dirt crits (as i found
last night)
So has anyone found a good battery config for ~1-2 hour runtimes with
a fairly small battery pack?
I was thinking of doing a series/parallel wiring config and get the
voltage up to 4.8 and then add 2 more batteries in parallel to
increase the mah
Please excuse my electronics ignorance
ps, having 4 months off racing is not cool
