    I have an X-treme E-bike. It sat for a few months, and even though the battery showed fully charged, and I charged it for 8 hours anyway, it now cuts out under high load. It shows fully charged, and works on flat up to Level 3, but going to level 5 or hitting a hill causes the bike to die. I have to pull out the battery and put it back in to reset. Does that sound like a battery problem or a different problem? Battery PN 48VEB-200. Sticker on battery shows JKBA BPMD00118 48V/10AH. If it likely is the battery, what is the rebuild cost likely to be? Thanks.

    I need a new Battery for my electric crosscity bike

  • EBike Marketplace: June 08, 2020

    @Dennis – We’d be happy to rebuild/upgrade your battery for you. We’ve done Smartmotion batteries before.


  • Dennis Andrews: June 08, 2020

    I have a Smartmotion 48v 11ah battery that wont charge anymore because I didn’t keep the charge up on it. Most places say that they cant fix it because it has certain data that goes up to the display built in the frame of the bike. Its a Smartmotion Pacer. No dealers in USA so its china or Australia. Have you heard of this before?

  • EBike Marketplace: June 01, 2020

    @William – We’d be happy to rebuild and upgrade your battery, if possible.


  • William Searcy: June 01, 2020

    I have a reention 48v13.6ah that came in my samson ebike. The battery appears to be bad. Can you rebuild it. What does it cost? Can I move up to the next ah capacity and purchase it or one like the original?

  • EBike Marketplace: May 28, 2020

    @Iain – Unfortunately, we do not offer Dorado batteries in 36V configurations at this time.

  • Iain Rutherford: May 28, 2020

    Is it possible to buy spares for the Reention Dorado downtube battery. 13aH 36V.
    It’s the internal small circuit board for the battery indicator with 4 LED’s. Mine got wet and it’s fried the board. The bike works fine otherwise.
    Regards Iain

    @Daniel – It depends on what the repair is going to end up entailing, but we’ll be in touch with our current pricing.

  • Daniel Jarquio: April 20, 2020

    I have FIVE FLX REENTION Dorado 48V 17.5 Ah batteries that need repair. Can I just get a price quote over email? Shipping them will obviously be very expensive, and I want to know if it’ll even be worth it. I could just buy the 48V 21Ah version from another site, if it’s cheaper. Thanks.

  • EBike Marketplace: February 25, 2020

    @Bob – Please send us some pictures of what you have and we’ll see what we can do for you.
