G'Day. Here's a semi hypothetical question for you... I have read numerous comments telling me the Model S (in particular at the moment) is limited in its delivery due to a lack/shortage of batteries. Similar comments re the Model X as well, however, if this is in fact true, how is it that battery backed up SuperChargers exist, and, most of all, the Tesla PowerWall is going to be draining (pun) the battery supply for vehicles (at least until the Gigafactory comes online). Does it make any sense to have 38000+ orders for powerwalls, when all the batteries for them should be going into cars (first) ? Comments anyone ?
