If you search: ´dorado e-bike battery´ online there is a large selection of 52/48v of varied price &
length preferably sam sung or pansonic cells, I´m sure what you need can be had more cheaply than
juiced. I still have a 1st run CCS 21ah still charges to 53.v after nearly 5 years, but it hasn´t seen
use in 2 yrs. as that bike is now a parts bike,(r.i.p.) It is too short for my current bike. I could
still use it with a 6¨ hose clamp to hold it in place, but my current bike gets better mileage(60+)
with 13ah than the CCS ever did with 21ah.
