48v

48v 13ah 50amp 18650 dolphin battery. I bought for my mountain bike set up and just barely ever use it. So I am selling. Probably less than 10 charges on it. I thought I would use it regularly but with my road e-bike and a few other hobbies it sat all year. I am selling the frame locally and the bat...

Did you find anything about upgrading the software through the iPhone App? I am having a similar issue. It was working and now it is not. i am also using a thumb throttle as a e-brake.

Re: Sabvoton Curiousity

i have had the Sabvaton 72150 for 3 years. Works great. I started with a kelly and i had a lot of trouble getting it synced with the motor and I sent back and got the Sabvaton and been VERY happy with that decision. Hope that helps.

Re: Good resource for those in need of help

Good result! Just a shame that a knowledgeable guy like him seems to build a battery without cell holders but instead by glueing cells together and not using extra protection rings on the positive terminals. That doesn't appear very professional. I am not sure about all of his builds but my batteri...

Good resource for those in need of help

Below is my experience, I was not paid to say any of this: My bike, controller and battery were dead, I couldn't figure it out and then I connected with Victor on this forum and he helped me big time. In the fall of 2018 i had finished up a big build project. I had found an old cafe racer style 125c...

Re: Sabvoton MQCON review and documents

Warning: If you are buying a new Sabvoton, it is a clone and prone to dying prematurely. Sabvoton closed their doors in late 2014 and everything newer than that is a Chinese knock-off. Quality in these controllers tends to be very poor and they fail often. I don't recommend buying a new Sabvoton co...

Re: Motor Choice Advice for Motorcycle Class eBike

I built what you are looking to build - but I used a Tomos Streetmate frame. It is a small motorcycle/moped. I used a QS205 motor with 72v 18650 battery. Goes 50mph. Registers as a moped. Looks awesome, handles the roads well. Let me know if you want more details. Happy to share. https://photos.app....

Re: New or Rebuilt Lithium-Ion Battery Service

I'd be interested in your service. I am in Boston, so if we can figure out best shipping method, I have two 72V 18650 batteries that need some service. One has a bad cell and one needs two spot welds. I'd like to also connect them together through one BMS. Let me know your service costs and shipping...

Re: help sabvoton 72200 meltdown!

Well, if only one phase leg was connected, no current could flow, so nothing could fail. What is more likely is that the other two unconnected phases touched each other and shorted together, or both were touching the same piece of metal somewhere on the bike, shorting together. (or one or both were...

Re: Sabvaton Power switch & throttle

Hi, sorry you're having issues with the sabvoton. Just to be sure, is the sabvoton throwing any errors? I haven't heard you mention a tft screen, so I'm assuming you dont have one. Did you get the version with the tft screen? If there's an error the LEDs on the sabvoton will blink. Is that going on...
