Yesterday I set my HR Storm HID battery on the charger and it charged for a few hours. I pulled it off and threw it in the bag for a night ride. I have decent light when I hooked it up on the trail, but after only a few minutes it started to flicker. Within 20 it was nearly out.

So I need to test the battery and I need to test the head. Thoughts on how? Assuming it is the battery, should I just rebuild it cell for cell? Maybe I should hack job it and build a smaller Li battery pack for it. Might be nice to not have such a huge battery.

If it is the Head, thoughts on frankensteining the head? I like the HID (though all my other lights are LED). I have a hand full of old JET HID bulbs laying around at the shop.

Time to experiment.

My thoughts...The fact that the light worked if only for a short time would indicate it is something wrong with the battery ( or a connection ). If this light is using a NiMh battery I would consider upgrading it to a Li-ion battery. You could go with something like this > http://www.batteryspace.com/li-ion18650battery148v4400mah6512whbatterypackwithpcb.aspx
and with one of these > http://www.batteryspace.com/compone...atorandledindicator4longtrail-techfemale.aspx
Personally, if it were me I would rather prefer a four cell battery so it would be lighter but the 8 cell would give better run times. You would of course need a 14.8 volt Li-ion battery charger and have to do some DIY soldering to adapt the connectors.

Last but not least, I might as well say before others do. $89 gets you a new Magic Shine with everything you need which is of course a lot less than getting a new battery setup...Not to mention another $100 if the bulb or ballast goes up.
