Make that 22.5 km.

I drove with an eye on the volt meter, being careful not to draw the voltage down too far under load. Below 5.25v under load brings you close to battery damage/cell-reversal territory.

For the first 15 km, I set an arbitrary lower limit of 5.8v. On the last run, 5.5v. I was watching the batt with the lowest voltage at the start of the drive (which doesn't necessarily mean it would be the first to sag below 5.25...).

Anyway... next on the list for the ForkenSwift...

1) remove the motor so it can be re-installed with the terminals in a better location. clean & repaint it while it's out

2) clean up & paint "motor bay"

3) fabricate & install front battery racks

I've been thinking about battery load testers again. I'd really like to make a tester which can be left unattended. So it needs to:

a) switch off, when the battery voltage falls below 5.25 volts (higher is OK too - as long as it doesn't go below 5.25).

b) record the time of the test
