Cheers for the review Scrivo. My two 2yr old cheapo chinese batteries died an hour and a half into a spin tonight after a full charge. Time for new lights. Very tempted by your recommendation here. Especially by the fact that only one light is required. One question, I normally put my helmet light battery pack into my backpack. The battery on this looks pretty big. How big is it roughly? What way are you running it? I would have thought mounting it on the bike, top tube or wherever, would mean major hassles with the cables to prevent straggling and snagging potential.
Thanks, Simon.
