I've briefly toyed with the idea myself John, but the discharge rate of the nominally equal capacity Ping units is low for the Quando/Torq 1 motor. It would work ok but I'm concerned the stress on the cells would mean the actual capacity/range would be appreciably lower and the life could also suffer.
Having said that, the li-polymer battery that eZee now supply also barely copes and as A to B has shown, it's actual capacity when used to the full is as low as 7 Ah, not the nominal 10 Ah. It also spends most of it's life on battery meter amber when the throttle is fully opened, even when new, so the cells obviously struggling to maintain the voltage. Also they are sometimes barely reaching two years so the Ping will probably perform as well and last longer.
The Phylion made test Li-ion that I've been running for almost two years now was much better in both respects, difficult to get off battery meter green for the first 200 charges even on tough climbs, but eZee didn't adopt it due to continuing suspicion after the previous experience with Phylion. Looks like only a two year life though, since I got the first cut out on a long very stiff climb at 20 months. It instantly recovered to full power and completed the climb though, and hasn't cut out since, so it should reach January and two years. In a less hilly area and with less brutal treatment it would be much better of course.
