Re: Nanjing far driver controllers

Lol someone online is offering support for these controllers on Facebook. He calls himself " FARDRIVER" and says he represents fthe company. He was charging 30$ for an email and 50$ for a phone call...: but, this morning he got pissed off ( at technical inquiries) and changed that to 300$...

Re: QSmotor 8kw, how big battery needed?

I started thinking about what you all said. 8kw motor with 70ah battery would give me either highway speed or 100mile range but not both at the same time. My question is, what would I need to change to get closer to having both? Would having a bigger battery (100ah, 120ah etc) do it or would I need...

Re: Suzuki 125 build battery question

You need about 14p for a good, solid, 300A from a p42a pack. Given all IR is congruent. I have seen some very powerful p42A built batteries. 10p is still going to be really strong. Thanks…KeifRichards posted his 9p pack got pretty hot in 60 seconds. you think the additional parallel cells would sol...

P42a cells 33A temp test

Made a quick video a while back testing the temp of some p42a cells at 33A. Used this info to estimate the temps I can expect to see with my 9p pack at 300A. Not the most scientific method, but quick and easy.

Looks like its gonna heat up quickly at 300A

Re: Suzuki 125 build battery question

I used the same batteries. With cooper series connections. I tested my 9p pack at 300A and it reached 55c in 60 seconds. I found the batteries’ limitations are thermal. So, given good, low-resistance connections, you can get 45A from these cells, but not for long. I plan on running my 9p pack at 250...

Re: Nanjing far driver controllers

Is there a Sabvoton rated at 96v and over 450 phase amps? I looked at their lineup but didn’t see anything more powerful than 200/450A and 76V. They seem suitable for bicycles, but not so much for faster vehicles. What are u using the controller for? My current build is a small dirtbike with 12/14i...

For the money..Sabvotons work so smoothly. App and software both work fine

May I ask what firmware you received, SW2.33?
And are you willing to share them?
The “updated” firmware shows the same version. I have no idea if its actually any different. He sent me 2 versions of firmware, can and non can.

Pm me your email if you still want it.

Re: Votol EM-100 & EM-150 controllers

So Harry from qs sent me updated firmware and called me on the phone to walk me through the update. The new firmware didn’t fix it. Will still save all settings except current and overvoltage values, which go to 0 when key is cycled off/on. I apparently bricked the controller messing with the “ports...

Re: My new Votol controller died. What is a better option

Thanks. Yeah I figured that out. I can save any changes except overvoltage and current. I can only see rpm in the dashboard when I connect with the CAN enable box unchecked. When the box is checked, i get no rpm when turning by hand. Its a mess Vid below of what is happening, if you’ve got a minute ...

Re: My new Votol controller died. What is a better option

Yeah. I just can’t figure it out. I tried reloading the initial calibration, it’s still inop. The problem is when I connect, it often only loads some of the values. When I first connected, I immediately saved a backup to be safe before making changes. I hadn’t realized it only loaded some values. So...

Yeah it wasn’t connected when I took those pictures. It will connect and show it saved changes, but the current and overvoltage always go back to zero after reconnecting.

I tried importing the original parameters, but Im still not anle to save it. It goes back to 0 for busbar current but all other values will save. Ive attached pics of the saved parameters. Maybe something obvious is incorrect?
