IO, your TBO = battery life. There's no maintenance on the motors except bearing wear, so it's reasonable to accept this. Everything else will be simpler than it is now - everything. Isn't this a reasonable initial tradeoff to make? I say this as my aircraft is stuck in Chicago 1800 miles away from home with 2 trashed cylinders and one bad mag. If it had been electric, that airplane would have been home weeks ago for a fraction of the cost. Down time of exactly how long it would take to FedEx a new battery to me... Time is money.
