Yeah, how many posts say, If ida read this first.... Hard shell pack cells definitely have an advantage, especially for larger AH setups, and Pings offerings are just a bit small for running a big x5 motor in hilly neighborhoods. But really , for the majority of us with a 600 watt bike, putting the ping pack in a toolbox is not so hard to do, and there is no question who is the most helpfull when the occasional problem does happen. I'd love to see him offer some modular packs though, like 12v 10 ah blocks with connector plugs that could be used to build different sise, shape, packs. That way you could replace a dead cell, or upgrade to 48v easy. For the x5 crowd, a 30 ah 60v pack with 60 amp continuous bms would be perfect.
