thanks so much! one of those Pings will work nicely. now i just have to save for them. i might start with a single 15ah pack and see how much runtime i get. if it's good, i might get a 2nd one to keep charged and in the trunk as a spare, so i don't wind up walking my scooter back home due to a depleted battery.
2 things: first, Slunce no longer has a working web page. 2nd, the nail in the coffin. there are more than a handful SLA's...you were right.
