Replacement battery packs for Switronix TL-50?
 

Hello folks,

Just received the TL-50 in the mail and loving it so far, great light and extremely sturdy, feels like a tank. The battery lasted 3 hours which is great, however, I would like some extra battery packs. I know they sell the battery pack, but for $88USD. Have any of you diy'ed a battery pack? Or found a similar pack for cheap and just bought an extra plug or something?

Thanks!

Sam
