Haibike Sduro Battery by Yamaha

Yamaha Haibike Sduro Battery

We recently got an up close look at a 36V 11.0Ah Yamaha battery for the Haibike Sduro e-bike. It's pretty sleek and slender to blend in well with the frame to give it a slightly more covert look than some of the other bulky batteries out there. But let's take a look inside to see what we're really getting in to.

Haibike Sduro Battery By Yamaha

Here's what the pack looks like out of the case. The bottom cap is secured only by 4 screws and the pack slides smoothly in and out. There are 40 total cells wired up in a 10S 4P configuration. It's long and the cells are hexagonally stacked no more than three high. With current state-of-the-art cells, this pack could be upgraded to 14Ah. The top circuit board is absolutely massive even though the chips are concentrated in two areas. There are metal tabs from each set of parallel cells soldered directly to the board.

Haibike Sduro by Yamaha Battery Management System BMS

Here's a closer look at the BMS with some of the connections. There is lots of silicone glue to cover any potentially exposed metal to keep short circuits to a minimum. The charge connector utilizes the blue and white wires so it's not a simple + and - connection. There's even a little white wire on the discharge port. This makes it difficult to replace or repair if the BMS ever stops working, not to mention the custom size it's cut out in.

    Hello, this BMS can be safely disconnected from the battery pack and the cells can be replaced? Battery/BMS will start again after reconnect everything together?

    @Tracey – It would be best to call up Haibike first and see what the error code means exactly.

  • Tracey Stafford: June 18, 2020

    Hi I have 2 haibike batteries that are flashing f and e. Can you repair them please

  • EBike Marketplace: June 17, 2020

    @Jean – We’ll be in touch with our current options.

  • Jean Lewis: June 17, 2020

    I wonder if you can help. My husbands Hai bike sduro 7 seems to have stopped working, he has been told it needs a new battery and he was quoted €600, I wondered if you could re-cell the battery and if so how much it would cost?
    Many thanks Jean

  • EBike Marketplace: May 11, 2020

    @Jim – No, we don’t sell replacements, but we can rebuild/upgrade these.

  • Jim Wade: May 11, 2020

    3 questions — 1. Do you sell replacement SDURO batteries? 2. Do you rebuild these batteries? Is it okay to exchange a 400wh battery with a 500wh battery? Thanks, Jim

    @Fred – Thanks for the tip! Not sure those are official Haibike/Yamaha products but we’ll check them out.

  • Fred: May 04, 2020

    Hello, looks like the pic you posted might be a 400wh, tried doing a conversion calculator, 11ah @ 36v = 396wh
    My haibike with the yamaha battery is 500wh, so with same conversion its closer to 14ah. 14ah @ 36v = 506wh.
    There is a small company in europe selling 745wh replacements, but he can ship to north american, not sure where he is sourcing the cases and controlers, but he is doing good business and supplying a well needed upgrade, I think he is trting to find a north american distributor or builder, might be right up your alley. Its a big upgrade from the stock 400/500. Cheers! Company name is ebike vision.

  • EBike Marketplace: January 28, 2020

    @Nay – We do not stock Haibike battery chargers. You should contact Haibike or one of their dealers directly.
