Does anyone know of a good replacement battery for my Golden Motor Magic Pie 3 hub motor? The battery that was on it was a 48 volt 20ah. Looking for one that would attach to the bikes water bottle cage bolts. Thanks,
You'll want to match the voltage (although if my memory serves me correct; the MP3 can take a 52v pack) and ensure the new battery pack can deliver enough current to meet or exceed the controller's maximum battery current (I believe it is 25A for the MP3 but you'll want to verify). Your capacity (in Amp Hours or Watt Hours) will determine your range. em3ev.com has always been my go to recommendation for battery packs.
