I have used Taskled HB flex to drive my other mod http://www.candlepowerforums.com/vb/showthread.php?427550-My-New-Magmod-Project-13x-XP-L-12k-Lumens and am looking to see if anyone one else is doing any drivers as powerful? I have 3 more lights coming and am looking to incrementally upgrade the specs.I am looking for 5s lithium input (~18.5v) and ~48v 3 amp output. Anything else on the market?
