I have a question about a possible way to quickly discharge my Inspire 1 batteries. I have a 400 watt programmable DC Load. I'm wondering if I want to discharge these batteries, what wattage or current would be safe to use. Also, I know when you turn on your Inspire 1 and just leave it the AC will shut itself down when it gets down too low. Does anyone know if this is the battery shutting things down at a low voltage point or the AC? I'm just wondering if I can put a specific current setting into the DC Load and walk away and the battery turn itself off when it's totally discharged, or should I make an external circuit that shuts off the DC Load when the battery get's to a specific voltage?
