You manage very well, you should hear me speak German, you could make a comedy hour of it, and with an hour, you would be short in time (in this hour i would only be trying to ask where the toilets are)
Why don't you get an Intelli V3 or V3.1 charger (diff between the 3 and 3.1 is 3 or 5S lipoly packs)
You could make a 12V from an ATX powersupply. (tested and approved, by me..)
