Hi All, I wanted to report my findings yesterday. I went up the mountains and completed depleted my bigger 7.6KW battery and my 1.4KW battery. So when I started to head back down obviously The car would only allow "Auto" and not "EV" mode. I found that using the "L" button regenerated the 1.4KW battery with in a minute or two and then my car switched over to the depleted 7.6KW battery and started recharging it. I read ( i think on the CMAXX energi forum) that normally the regen is about 4KWH when coasting, but when using the "L" option, which slows the car down quickly and can be applied at any speed, will regen at around 35KWH. I would agree with this, since within 40 minutes of using the "L" while going down the mountain, both my batteries were fully charged and I was once again able to drive straight EV back to my house. Although when I try to just drive in normal stop and go city driving, I don't get enough regen to justify keeping it in "L" mode.
