I think I'll pick up 1 6000 pack and see how I like it.
What charger are you using that you're stuck at 2amps, you should be able to charge at 1C which would be 6 amps...
I'm really not sure what's going to happen at Willis. The track is really not that large and depending on the layout we either run stock or 19t, you really can't run mod. I'm hoping that the 13.5 will be alowed in stock.
