Thoughts on batteries

So the idea about recycling packs from old power tools is essentially dead. I did some calculations and figure that such a pack would weigh more than a given lead pack. yikes. There are a few lithium options that would be great but still very expensive, likely 10-12 thousand for a decent pack. Another option is the very cool sounding molten salt nickel or Zebra battery being manufactured by Cebi in Switzerland. No idea on the current cost as they are only selling to OEMs, but in the long run should be much cheaper than a lithium pack.
