I think most people would easily last 2 years on battery #1 in my example, thus every 3rd year they would need a new battery for $382. Thus my Question, the increase of 3-4X battery life is a no brainer... But the Repay for the money is only, 1.6-2.3X the #1 battery... So who is/would actually still do it.?

People seem to balk at buying bigger batteries all the time around here. And to buy a bigger battery and not get the extended range with it seems like a big/huge hurdle...
