Donteven, is is a defective battery, I wonder? It can happen that they are kaput out of the factory and would explain why you get this issue despite doing everything else right. If it were me I'd be tempted to get onto my dealer to replace my battery pack (if the **** things arrive any time soon - apparently the initial dealer spares orders are en route from China, but may be going by proverbial slow boat...). Do you know anyone else with a Vision you can test another battery pack with, or a local dealer with a demonstrater?
