(ET) Final snow-blow, this time with numbers.

[Christopher Zach <cz alembic crystel com>]

This afternoon I did pass #2 with the E20. I can see now why they built 
a "snow cab"; while blowing snow a 40mph gust came over the front and 
everything coming out of the chute covered me.

Impressive. Made it to the top, then proceeded to take windage into 
account while blowing snow.

Anyway, for the numbers: The Link-20 was online and I watched the 
current while blowing.

Idle: 30a per pack (2 packs)
Under normal snow: 100a per pack (200a total draw)
Heavy snow uphill 150a per pack (300a total)
Plowing into the 2 foot drifts 210 amps per pack (420 amps total)

So I have seen 400+ amps while blowing snow from these batteries. After 
blowing for awhile the batteries were down 20ah on one string, 18ah on 
the other. Voltages were 32 volts at rest dropping to about 30 volts 
under normal snow-blowing. Bit slower, but still ok.

Parked and put the pack on charge. String 1 was pulling 15 amps, string 
2 was pulling 17 amps at start of charge. Overall not too bad.

So there we have it. My driveway is clear and this latest snow should 
end soon. And yes, they're calling for snow on Monday....
