    One more photo showing the Yesa packaging. :) The white boxes within the shipping carton (above and below broken styrofoam strips in the middle of the photo) held the chargers (one shown). The battery pack was wrapped in plastic in the middle. -Cal

    :D My 48 V / 20 Ah pack arrived about a week ago and I've made a few commutes to work (~13.5 mi and 700 foot climb and descent each way). The Yesa LiFeP04 pack powers my Crystalyte Cruiser on a Target store Schwinn Ranger that I purchased on sale for only $120. Wow--this is what I had in...

    Yeah--that's a concern but rear lights don't need to produce nearly as much light as front lights so I'm probably going to run my penlight powered LED rears for now. I'm really looking forward to having a bright headlamp. I hit a deer on my commute about six years ago. I was doing about 60mph...

    Yeah--it's big, Marty. Might fit, if I can find a US dealer. I found plenty of 24V MR16 lamps, but this looks interesting and it's the first 48V LED unit I've seen. Thanks, -Cal

    Nice graphs, vanilla ice! From the graphs and the specs I've read, LEDs are not terribly efficient so has anyone tried flourescent? http://www.bulbamerica.com/Compact-Fluorescent-7w-MR16-Light-Bulb-3243-prod.htm?category_id=491 At 2700K, the color temperature seems too warm for contrast...

    ebay LiFePO4

    This is my first post but I did some reading here before I ordered a 48V x 20Ah pack and two chargers from Sam. Sam encouraged me to wait an extra 10 days to get the "new" cells so I'm probably going to be even more leading (bleeding?) edge. It should be about three weeks before they arrive to...
