    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?

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

    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.

    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.

    I bought a Populo Scout E-Bike that has no Battery. The company doesn’t make it anymore. The spec sheet says it held a 36V 13.5A/hr Panasonic, but the Downtube rack says REENTION on it. Can a stock battery from EMP be adapted?

    I have an Orbea Gain D30 with a Ebikemotion 36v downtube integrated battery pack, the bike was submerged for a few minutes and now a warning light on the control button is flashing.
    We have swopped out various components and the fault appears to be with the battery, can you supply a new replacement battery or refurb the existing battery.


  • EBike Marketplace: October 09, 2019

    @Lance – We do not sell second-hand products on our site. Maybe find some other online forum or classifieds?

  • Lance Richards: October 09, 2019
