These MTE P7s sound great, but their battery life seems to only be around 65-70 minutes? Our morning rides are usually 90-110 minutes and will soon be all in the dark, and we ride on some really dark roads so I need something seriously brighter than the dinky 7 LED Cat-Eye that I have now.
Are there other similarly bright lamps (P7 I guess?) that might have a longer battery life?
Thanks!
