Just picked up our Model X 75D this past Friday and having a blast. When I asked about battery maintenance, I received a circumspect answer about staying within daily limit. But, they suggested lowering the home charging amps from 40 to 30 or even 20 (saying that you get a more even charge - like filling an ice tray with less water pressure), and lowering them even further when on vacation to trickle charge. The forums that I have read have a lot of discussion about optimal daily charge (80% or less unless needed) and 50-60% range when on vacation, but little on charge amps (a couple of old threads on lowering it). Thoughts and recommendations? Thanks
