Great battery pack. I have tried it with my Solar Storm X2 and it has more than doubled the battery life.. On low power it has run for 25 hours none stop! On medium power it lasted over 7 hours but had started to dim quite a lot after the 6 hour point but there was no sudden cut off... Not sure if this is a good or bad thing. But I am more than happy and out on the trail it will give me more than enough time to do a really good ride if teamed up with the original battery too!
I have used this with my Solar Strorm X2 and although I have not used it totally on high power which is very bright anyway I have tested it at the medium and low settings. On low it gave me 25 hours of batter life and on medium it gave over 7 hours compared to the 3 hours I get on the original battery on medium power. The only down side could be a lack of cut off as it does let the light get quite dim and I turned it off not wanting to over drain the battery.
MUST have if your using your light all night till morning. just make sure you have it fully charged. important don't let salt water get inside battery even a little will screw it up.
I was very pleased that I received the new and improved version. Much better waterproofing, rubber casing around the batteries and improved pouch with long velcro straps to secure the battery anywhere on your bicycle frame.
