I'm thinking about getting an xb-600. There will be occasional times in the winter when it is cool and the batteries have less juice where I'll want a bit more range. If I added a battery to take it to 60V, but still drove it at, say 20mph, I am assuming that I would have better range then if I stuck with 48V...am I right? Am I wrong?
Second question comes from time spent in MN where people plug their cars in at night. They do this to keep the battery warm so they can start the damn things up in the morning. Has anyone tried to warm their batteries in the winter to get better range? Alternatively, has anyone tried to run a small 12V heater in the battery compartment (perhaps off a separate battery and with a temp controller) to keep their batteries toasty? I live in NC, so probably not an issue, but just thoughts.
