Ive had a Hope LED 2 for almost a year and have been contemplating getting a second battery as you can only get about 2 hours of burn time at the most. I just wish that Hope would make a long run battery instead of having to use two. Changing them on the move i'm sure would be a pain. So I went to my LBS today and ordered a second battery, it should arrive next week. So guess what the CTC Cycle mag came today but did not have time to read it before i went to the lbs. Got to page 70 of the mag and guess what, there is an advert from Hope. At the bottom of the advert is .................... "NEW! For this season "Epic" - Only Available on the LED options - 4 Cell Battery (compared to the 2x2 cell endurance option). Upto 20 hours burn time (3.5 Hours on full Power)" So I look at my watch, its 6.30pm the lbs closed at 6pm and they would have already ordered the battery. Typical I just hope they don't mind me going in tomorrow and canceling my order and now ordering this longer run battery.
