This sounds like the Enginer kit
. Seems like a very logical way to add battery capacity. One big question I would have is the efficiency of the battery to battery energy transfer. How well would that work?- especially since your energy draw is pretty large. Is there a safety that prevents you from drawing power off the pack and "charging" (or transferring power to it) at the same time?
$600/cell for additional cells?
Your add on pack would have to do it's own battery management.
If you stick them in the trunk - might need some active air flow too.
Seems like an "easier" way to start would be buying the pack from Enginer and hacking in the ChaDeMo connector. They might even help you with the process. I've written to them in the past, and they were quite happy to talk.
