From the limited reading I've done on LiFepo4, it seems that it's considered a safer alternative to lithium ion but the main drawback is capacity. Have these batteries gotten better lately and is anyone using them in single 18650\2xcr123 lights in place of lithium ion? Would runtime at various outputs be basically cut in half using LiFepo4?
