[ausev] A Battery Question...

[Brian Lasseter]

I have 18x 8 volt US8VGC batteries in my car.  That's 144volts nominal
pack voltage.  The batteries float charge at 185 volts, I set my low
battery indicator (In the Zilla Motor controller) at 110 volts, and my
battery cutoff is at 80 volts.

My question, is when should I measure 110 volts as being "low"?  Is
that 110 volts under load, under a small load, or not under any load?

i.e.  If I'm at a stop light reading 140 volts (after driving 25 miles
already that day), I can stomp on the gas, push 350 amps through the
Zilla to the engine, and the battery pack will sag to 107 volts or so
briefly flashing the "low" battery indicator until I take my foot off
of the gas.  Is that really "low", or am I waiting until a more normal
200 amp acceleration pushes the pack to below 110 volts, or am I
waiting for when the pack reads 110 volts while sitting at a stop
light?
