*I tried the Layman's Cell mod on my ZZ SE. I went to a local battery specialist in here in Michigan and had them custom weld me a 4 button cell with 4, 1.2 volt 40 mAh batteries in series for a total of 4.8 volts! The batteries were made by Varta and are the exact same batteries mentioned in Layman's post. I am sure of that since I also ordered the Layman cells.
I was really happy to get the custom battery when I saw it was welded and shrink wrapped and best of all It was almost the exact same size as the stock 2.4 volt battery. In fact when I fit it in my ZZSE there was no modification required.
So what happened... The proportional steering and drive both seemed to work since when I held the Zip in my hand and let the wheels spin it seemed to fly. However as soon as I set it on the floor and went I realized that the ZZ was SLOW. It seemed as if the ZZSE now had no torque. At first I thought that I just needed a charge in my battery. So I promptly went to a friends with a R/C hobby peak charger. I charged the batteries at .5 amp. When I attached a lightbulb and then a 5V LED directly to the battery the lamps lit up brightly. I definitely had good power. Yet still the ZZSE was slow (about half of the normal speed, with stuttering).
When I put the original battery back in, the ZZSE was back to normal.
I believe this problem may be related to one of the components on the PCB operating out of spec. Over Volted. I'm guessing that the part that was faulting was the A/D/A converter itself. But that is just a guess.
Long story short I think we need to get these new ZZSEs faster. I loved the results achieved when adding 1 or 2 extra batteries to the original ZZ and I am really hoping that we can get the same or more speed out of the ZZSE.
