LOL Music I like it.
man some tight streets for sure , but omg the tire coming off the ground is crazy.
I have slipped a few times and given my bike to much juice - on that setup someone's gonna flip.

yeah! I will also get the 5403 so i'll be able to compare both
i know everyone here is curious to see results!
I am preparing a 24s 10P a123 cells pack (the 26650) for that test to keep the discharge curve as flat as possible and not have any voltage variation from the lipo. It help top have precise data for comparing! when your ebike voltage dont vary to much over the time :wink: .. maybe it will become a 30s pack... who know 8)

Doc,
Wasnt your motor supposed to be 17kv?

You get use to it after you ride it for a while. On my 20" wheels I can't ride them out anywhere near as long as he is because it's too twitchy for me to control. He has some excellent control over his setup.

From the last PM i got, it will be 14 Kv ( and is under test now)
The equivalent of a 5303 i think...

I can't believe you guys are getting 20-25V of sag from those batteries, that's brutal on the batteries! When I dump 10-12KW into the controller I'm only seeing about 7V of sag on a fresh pack now charged to 125V. After the pack settles down to about 122V I only see 3-4V of sag. My battery pack is a 30S2P made from 6AH 25C-50C Turnigy Nanotechs.
When you guys upgrade batteries you are going to see a big improvement in performance. My previous pack was 30S3P of 5AH 20C Turnigy packs and it would get over 12V of sag on a full 125V charge and when settled down to around 122V would see about 8V of sag.
When I get more money in the future I'd like to add 3 more of the 6AH Turnigy cells in parallel with the other 10 I got now so I never have to worry about sag or running out of juice. Charging is so easy now that I have a 1200W bulk charger.

I'm confused. 125 volts at 200 amps and he only gets a maximum draw of 9kw according to the CA. ???? 125v at 200amps should provide up tp 25kw, no?
Also, holy voltage sag Batman! He goes from 125v down to 103v wile consuming 9kw. A lot of sag. I wonder how much sag he would see if he pulled 25kw. Lol. Why 22v of sag under wot when hes only hitting it with 70 or sk amps? (125v @ 70amps = 9kw which is what the CA displays under wot). Also, 30s pack, charged fully to 4.2 is 126v. Of tjat 126 volts u can consume 21v (if hot off the charger) (.7v x 30 = 21. (4.2 - 3.5v)). So with that said, shouldnt his LVC be set to 105v ish? Appears his voltage sag is so bad that even at a full charge , when he goes wot he is a few volts below where his LVC should be. Is it safe to go wot when ur voltage sag brings you down to 3.4v?
Edit: damn u zombiess, beat me to it.
