Kevin,
When was the last time you spoke to Bob about the Li-ion batteries?? I think you will find if you call Bob that his tune will have changed a bit (since we have talked numerous times about my tests). Jetcat Germany has been experimenting with Li-ion for a bit now and the new P-70 may even come supplied with a li-ion pack.
I have successfully flown a Jetcat P-120 for five flights without a charge on a Li-ion pack, Obviously they do have the amperage capacity to start the Jetcats....Not once but multiple times....They work!
