Norsk’s have 2 USB ports directly on them, could be helpful if you use them… I’m an Amped guy, never an issue…
The USB Port’s on a Norsk are pretty useless when the battery is going to be hidden inside of a shuttle without access to those ports. When it comes to your live imaging batteries Amped, Norsk, and Dakota Lithium are all very comparable and will do you well.
In my personal use and retail experience Amped is by far the most popular and has had the least amount of problems.
