I have a battery pack with 7 pouches 25.6vdc 11ah. It would take 21 of these to replace. Is it worth it at 10 dollars each? https://sfbay.craigslist.org/sby/for/d/efest-purple-4212-imrmah-37v/6704892675.html Is this chemistry obsolete? Seems it was in use 10 or more years ago. These cells may be a decade old or new. I can't tell. I am using the pack(2) on my Zuumer. The only place I know where that have taken off is in San Diego. The police and EMT use them. I am reluctant to use 24 volts as I suspect I may not get the full use of the battery before the controller cuts off due to low voltage. I don't have a manual so I'm not sure. I did get the Zuumer working on 4 lead acid 12 volt batteries but not much success. Maybe I could use another chemistry but I'd like it to fit in the two containers that came with the scooter due to space considerations. Lawrence Rhodes
