Dale,
Great info - thanks!
I guess once one is primarily flying electrics setting oneself up for an 8s charger is not an issue. However, since so many of them are 6s chargers, I keep thinking in terms of packs which are fractions of 6s - either 2p3s or 2p4s rather than just considering a single 8s pack.
At 80A, the EU-1A must really move out. If only you could get 10 Ah in there instead of 5...
