Saw various reports of the 1st gen charger - or chargers, if equipped - failing. As the 1st generation chargers (40 or 40x2) were replaced with the 2nd generation chargers (48 or 72) earlier this year (I think?), I am seeking information as to how the 2nd generation chargers have held up. Prior threads concerning the 1st generation charger speculated reducing the charging rate to be less than 40amps lessened the stress/wear on the charger. As such, is it best practice to generally charge beneath the maximum of the charger - i.e. limiting charge rates on a 48amp charger to 40 amps or 60amps max on a 72 charger? FWIW I opted for the 72amp charger and am somewhat concerned about this critical component not being covered under the unlimited mile battery/drive-train 8 year warranty. Obviously still covered under the 50k / 4 year factory warranty - and then the extended warranty, if purchased - but if regularly baslting a 72amp charger with 72 amps (or 48 amp charger with 48amps) will degrade it faster, I can throttle back for my regular charging. Thoughts?
