@Habahnow @flashlight The AA Zebralights used to cost less and support 14500. The current models don’t support 14500, which is a major downside now that we have 14500 batteries with a capacity as high as 1250 mAh (4.6 Wh). That’s about 50% more capacity than the best NiMH AAs and even exceeds disposable lithium (except at very low loads).
