battery for electric bike
Bought this for a 48C, 1000 W front wheel electric bike conversion., Battery was still heavy at about 20 pounds, but much better than lead acid. Seems to work...have not used it but a couple of times. The shipping box was a cheesy Chinese version and it came charged, which surprised me. Very expensive in my opinion, but hey, it worked!

Pretty nice desktop microfuge
Fairly complete. The rotors pop on and off via a simple friction spindle. Not bad for the money.

Worked. Arrived damaged from USPS, but they took care of it.
Had so get a replacement due to USPS damaging the first one. Otherwise, worked. You will need a battery and maybe a battery cover.
