Re: (ET) E-15 not getting out of first speed

["Briggs, Michael" <Michael Briggs unh edu>]

The batteries definitely aren't completely dead - they can hold a charge 
well enough to mow for a while. I'm wondering if I'm just not charging 
long enough. I'm using a Landis charge controller. 

For people using a Landis charge controller, how long do you normally 
charge your batteries after they've been pretty thoroughly depleted?

I installed a 240 V EVSE capable of up to 10 kw for charging my Nissan 
Leaf (which can only charge at 6.6 kW max), so maybe I've just become too 
accustomed to quick recharging, and haven't been charging these lead acid 
batteries long enough....

Have you measured the battery voltage under load?  Under those conditions a
voltage of 5.25v per battery (31.5v for the pack) indicates fully
discharged.  If they can't maintain that with a fresh charge, they're 
pretty
much junk.

Unfortunately, that's about all I have to suggest. I no longer remember 
much
about the GE control scheme since I've been using a solid state controller
for many years now, so I'll leave further debugging to the GE experts here.
