E-bike battery pack creation for Sparta Ion and Batavus for really cheap price 

Yes, below the battery, if you check the video of the full ebike reparation you will see how every single item fit on this space. Thanks. DJ.

Hi, The BMS it works as expected, it is controlling the overgarge and overdischarge as expected, the maximum voltage registered on the packs are 4.17Vdc avg, and the minimum is 3.78Vdc, so always between the expected levels to ensure the live of the batteries. Yes, you can reuse the original Sparta Charger, is the one I use every day. For your information the max range obtained so far was 135Km with one charge with medium assistance level and changing between med and low 178km, I charge the bike every week or so, very convenience. Thank you for the comment.

Hi, You can do also by yourself, I have a video on my channel showing how to do it. Just a suggestion. Regards.

No, because part of the controller is embeded into the battery and bms, they already design that to avoid this easy solution.

same Question here. If I looked closely the grey cable wasn't connected, is that correct?

I used a multitool and sawed the sides open. Be carefull: don't saw to deep or you will touch the batteries

Hi, not really, the problem on that bike is that the driver control is partially in the battery pack. It is design to avoid customers easy solutions. Bedankt

@@Davideljeringa Thanks for your reply. Then it is necessary to overhaul the engine for the new driver, right?

Hey, I am looking for a solution too. The cells are good enough for me but the BMS is burned. Please let me know if there is any place to buy a BMS or the characteristic of it. No clue about what could work with this special li-ion battery. Please help me !!

@@rottelHQ Hey dude, just letting you know that I never got it to work either. I ended up buying 2 12v motorcycle batteries to run in series for 24 volts. Doesnt look nice, but it works! These bicycles are horrible and once the BMS breaks its basically over.

Hi Aston, The specs of the baterry that I replaced are: 24Vdc Ni-Mh 9000mAh-11000mAh (depend the year of the bike). The specs of thebattery that we create are: 24Vdc LI-ion 21000mAh, Nominal voltage 25.9Vdc. Current continuous 17,5A, Current peak around 500A. I hope this info is good enough for you.

Hi Harold, What dimmension in particular do you want? As you can imagine is a lot on the 3d design

Yes it's confusing

That is for balancing the 6 pack parallel batteries together, after all 6 packs are same voltage after waiting long enough (without using a charger), he will remove the wires on one side.

Not. You are to open the hub motor, dispose of all the printed circuitboards inside, solder the three wires to the wires that come from the coils of the motor and close it again. Use a cheap Chinese e-bike controller like nl.aliexpress.com/item/1005001519752387.html?spm=a2g0s.9042311.0.0.27424c4dfrXLR3 (you see one in the background). You can, but don't have to lead the hall sensor wires outside. It will work adequately without. And you shall have to save more on the motor wire diametre than is good to get it all through the hole. But I know it has been done You do need to use a PAS sensor on the pedal (in Holland that's law) or a throttle controller. The torque-sensor on the rear axle that is used originally cannot be used without extra logic (which you have to design and build yourself)

Hola Sebastián, Este es el bms que yo instalé: € 3,47 6％ dto. | 3S 4S 5S 6S 7S 15A limit 20A 18650 ion Placa de protección de batería de litio 12V 24V 29,4 V Li-ion Packs BMS con disipador de calor de equilibrio a.aliexpress.com/_BU2CXx Con respecto al inglés lo siento pero no dispongo de mucho tiempo para poner los subtítulos. Si tienes cualquier duda por favor no dudes en contactar conmigo. Es un placer poder ayudar. También podemos hacer una videoconferencia si necesitas más información, por mi parte no hay problema. Saludos

Muchisimas gracias por tu respuesta ya compre todas las herramientas para hacerlo! Con respecto al bms he comprado el 7s de 29v esta bien? No m queda claro debido a que el enlace dispone de diferentes variantes a seleccionar, de nuevo gracias 🙂

Hola de nuevo, Si en efecto el 7s 29v es el correcto si tu objetivo es crear una batería de 24Vdc. Saludos.

Gracias 🙂, y finalmente dejaste la misma controladora o la reemplazaste tambien??

@@sebastianaguilar576 A que controladora te refieres? El controlador del motor? Si es eso no, he tenido que sustituirlo debido a la complejidad del sistema completo. Estoy acabando de editar el vídeo del motor, es ese podrás entender el porque de no poder reutilizarlo. Espero poder subirlo hoy al final del día. He utilizado varios tipos pero los que mejor han funcionado hasta la fecha han sido los que no tienen display LCD, los de led son menos estéticos pero muy baratos y van de lujo. Saludos.

Hey if you are not so smart and want to spend your money in this way, please go ahead and let the smart people interact with each other bro…..🤣

@@Davideljeringa dont understand what youre saying bro...has nothing to do with intelligence, but i guess u dont have a lot of that😅👍 and if you are really that smart then why not build your own controller to wiseguy...
