Re: Greentime controllers

I found more info on the hua tong thread about greentime controllers. Here's a conversation between stewrobb and Leo from a year ago : Photo 2012-08-14 23 31 54-png.jpg Also from stewrobb in the hua tong thread : The seller clarified "K1 K2 dial gear", you connect them together to advance timing for...

Re: Greentime controllers

Well my lvc is set to 84v, so I don't think lowering it will do any good. Also, maybe it's unreliable but Leo to me the e-brake would work up to 100v...

Edit : he told me "regen work up to 90-95v we don't set it higher". Is this setting related to lvc ? Because it is supposed to be 84v in my case...

Re: Greentime controllers

Thanks John. I did the current mod on my hua tong last year with desoldering braid copper and it works fine. I'll do the same on my Leo12. For the e-brake, you can't be more right about it ; Leo doesn't understand well what I wanted and he told me that the hi-level braking force was higher than the ...

Re: Greentime controllers

I own a custom made 12 FETs irfb4110 controller that I bought from Leo. I guess this is the good post to review it (not as exhaustive as method's). For the price, it is a very good controller so far. I used it with 24s Lipo to power my 26" magic pie. I discovered a slight stuttering at start from ti...

Re: Speedict Ebike - Anybody seen/tried this?

Just a quick question : is the governor suppose to work right when enabled or it needs the throttle cables or something ?
In other words, how do we make it work ?

Re: Speedict Ebike - Anybody seen/tried this?

Hi Danny,
Now that the last release has came out, do you guys plan to release the "battery gauge" function in the next release ? The user could have the choice between an analog or a digital meter. Such a function would be very handy.

Hi Danny,
Can we conclude that your company will lunch an ebike controller that has a speedict in it ?
Also, will the function of a battery gauge on the display screen be on the next firmware relase ?
Thanks

Re: Changing the LVC in a 72v generic controller

Hey Auraslip, can you share with us some of your napkins math calculation ?
I want to run this cheap controller at 24s, so I'd like to increase the LVC to get the regen to work at higher voltage.

I hooked up the X pad to the ground through my brake levers and it does brake real strong (still don't know if it return current to the battery). I haven't tried the XS pad, maybe you can try it for us ! By the way, I see your controller was made November 5 2011 ; weren't the new controller supposed...

After hours of reading, I'm a still a little confused about the diameter of a motor vs the width. eg: If you have a Magic Pie and let's say a HT3525, I think the HT3525 (35mm wide stator) would handle more current than the Pie (18mm wide stator) before showing signs of saturation but the Pie as a mu...
