    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.

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

    Hi, I have a Reention Dorado 36V 12AH battery. It is not recharging. Looking to get it replaced or rebuilt. Can it be upgraded to higher capacity.

    Thank you

    @Larry – Usually an 11.6Ah battery can only be upgraded to 14Ah, but it depends on the case. We’ll be in touch regarding pricing.

    I have an ebike with Retention battery with the numbers ABM9-4811-O-P-WP-QT-0151469
    I believe it is a 48V 11.6AH.
    What is the replacement cost for this battery and the cost of a 16AH or 17AH upgrade?

    @Mike – Can you send us a picture of your battery and the screws you’re looking for? We can probably supply you with them.

  • Mike Crawley: July 30, 2019

    I have a second-hand REENTION battery case that’s missing some of the screws that go from one side of the case to the other, they’re about 74mm long (3 inches perhaps) and have a tiny nut that fits into a hexagonal hole in the case. Do you know where I can purchase spare screws ???

    @Tom – We don’t necessarily stock replacements, but we have some scrapped batteries we can salvage parts off of.

  • Tom: July 10, 2019

    Hello! Do you have replacement parts for this battery case? I have a customer with a finicky switch on his Smartmotion battery. I am looking for a new end cap which has the board & switch to restore functionality. Smartmotion USA at one time told us this was due to a programming issue, the battery would not turn on due to some sort of protection circuit that was programmed with too low a threshold, but I feel some of them are just faulty switches?

    @George – Typically we don’t change the voltage because that would require more changes in the electronics and could end up decreasing the overall capacity of the battery pack.

  • George: June 18, 2019

    I read where you said you don’t recommend changing the voltage, but can you? Mine is on a BBSHD capable of more than 48 volts.

  • EBike Marketplace: May 28, 2019

    @Amine – We don’t recommend changing the voltage, but we can upgrade the Amp-hours.

  • Amine Chaoui: May 28, 2019

    I have a reention 48v 11amp can you upgrade to 52v and higher amps??
