I've found it takes several cycles to sort itself out when I've got mine in a pickle :?

As you say voltage is the key thing.

Do we know enough about the batteries to be able to tell much from the voltage? i.e. has anyone published a voltage/charge curve so that from a voltage we can get a rough idea of how much charge is remaining?

It's not a good way of indicating the state of charge.

However,
If the pack sags to 160V under 100A load it's probably over 80% full. If it sags to 150V there's about 30-40% left. If it sags to 140V, find a socket quickly!

Something I keep meaning to add is a nice voltmeter and ampmeter, trouble is I dont want to start turning it into the mad professors mobile with dials and gauges everywhere :lol:
