This seems counter-intuitive. I would expect it to be the other way round, and it has been in previous experience. That is, you have longer cycle life if you routinely discharge to 70% DOD, than you get if you routinely discharge to 80%. Maybe something else was different about those batteries? > My trip is 34mi, and mostly highway speed of 60+, after analysis, 50mi > range is the min for us at 60mph. Now this lines up. There are exceptions (batteries designed for high current), but in most cases you want to discharge your battery at no more than its one-hour rate (C1). That means that if you're going to drive 60mph most of the time, you probably want to have at least a 60 mile range (battery flat in an hour).
