I get at least 4 hours on tail lights in flashing mode. I charge them over the weekend because it is convenient rather than they require charging.
I think 3 45 minute rides on a magicshine on high isn't too bad. The brighter the light, the more juice it requires. I use 3400 mAh batteries in my flashlights. Perhaps upgrading the batteries in your battery pack to higher capacity ones will give you more run time.
Yes. And thank you. 18650 batteries typically last longer. Buy good ones, the extra cost is worth it. I use nitecore 2300mah batteries in my flashlight (nitecore p16) and they last twice as long as the trustfire brand and the no name brand ones i bought online. Buy a good quality light and better quality batteries, because your life depends on it.
