I put a volt meter on my pack to see how much its sagging under load.  I
see the resting pack voltage is about 64V (5x12v SLA).  When I
accelerate the pack sags down to about 55 or so and then climbs as the
scooter increases speed.  On a freshly charged pack it got to 110V!!

I dont think Im inducing current into my sense wires because the voltage
goes to 64V when I let off the accelerator and coast at high speed.  It
seems this voltage it right.  If I shut the scooter off then this is
where the pack sits.

So, whats causing this voltage and can I trust the sag voltage when the
scooter is moving very slowly?

thanks,
Aaron
