I voted no, but with caveats. I don't need a second pack, but if my pack failed I would like to have a replacement option available. It would also be nice to upgrade the pack as cells continue to improve. In a couple of years we will probably be able to get 18650 cells that have 50% more capacity. It would be nice to be able to take advantage of that. Imagine a 7-8Kw pack with the same size and weight. If I had that my Alta would cover 90-95% of my dirt riding needs.
I wonder what happened to the packs that Alta replaced under warranty? My pack is currently good and until it fails I am not willing to break it apart. It would be nice to experiment on a failed pack to see if it is possible, and what you would have to do, to replace the cells. If we can find out if there is an auction on Alta's remaining physical assets I would like to buy a failed pack or two to experiment with them.
