    5 Speed Manual DR650 Conversion with QS138 and BAC8000 (It Rips!)

    Can I hook 58.8v 14s to Nuvinci Dev kit controller?

    I've got all the parts to make my bike 14s instead of 12s the only thing holding me back is the NV controller. Does anyone know if it will take 14s lipo or 58.8 volt? The site says its good for 48v E-bikes but that term can vary.

    NuVinci Delta Series

    Looks like Fallbrook has a new transmission out called the Delta Series. There is a video of it in a side by side atv on this page. http://www.fallbrooktech.com/nuvinci-technology They call it a 43mm CVP and they say the ATV has 30hp. I now want one for a bigger E-motorbike :-D

    Nuvinci Dev Kit Problem

    If I cant get this sorted by Monday I will call Nuvinci for support. I figured I would bounce my problem off you guys first. I've got the Nuvinci controller and servo hooked up on the bench. I created my config table and shift table and successfully loaded it on the controller. I played with it...

    Stinky with 80-100 and Nuvinci. NEXT BIKE Teaser pic inside!

    The best the bike has done was 62 mph. Realistically it does 40 mph without completely destroying battery life. The 900 watt bulk charger works great and I am balancing using a RC charger. The $230 Turnigy battery pack has last 1,500 miles which is absolutely astonishing to me. M14YQVW_nOI...

    Found a source for 80-100 while HK is sold out $170 shipped.

    I messaged this manufacturer for a price quote on 1 motor. http://skyhobby.en.alibaba.com/product/476092519-212631801/R_C_ATN_series_Outrunner_Brushless_electric_motors_for_RC_toys.html I was very surprised when I received this message back, Dear Mr. Kevin Gautier, How is everything? so...

    Senosring 80-100 motor using a commutation encoder?

    I ran across this gem in the latest machine design magazine. http://www.digikey.com/us/en/ph/cui/amt303.html looks like it could make sensoring motors very easy for $35 :-D and its programmable!

    Anyone spoken to HK about gettting bulk bare cells?

    I feel like it would be a dream come true to be able to buy the 5ah or 8ah 1s cells used to make HK packs bare. Has anyone every tried that with hobbyking? I would like to be able to parallel at the cell level and avoid the mess of 8+ sets of balance leads and parallel boards.

    80-100 thread size!?!?!

    Hey guys! I'm working on an Inventor model for my E-bike. Anyone know the thread size of the 4 mounting bolts on the 80-100? I don't want to take my scoot apart just to find the thread size. Thanks!

    Starting my second RC build.

    I caught he EV bug about a year ago when I completed this build: http://endless-sphere.com/forums/viewtopic.php?f=35&t=20732 After a year of thrashing on this ESR w/ 80-100 and Kelly I found the setup to be VERY reliable. In fact I used 3 sets of SLA's (thank you batteries plus warranty)...

    Tandem 80-100's timing/controller ?'s

    Has anyone mounted two brushless motors on a common shaft and run them off one sensored controller? I cant think of any reason it wouldn't work. Any advice on accurately setting the timing between the permanent magnet cans? I realize I could just run a single 80-100 at a higher voltage and make...

    Has anyone tried to build a charger with IC charging chips?

    I ran across this chip http://www.intersil.com/data/fn/fn9105.pdf Seems like a nice way to build a charger that is compact and balance charges every time. This particular IC is good for 2A which is acceptable for my purpose but I would love to find one that charges a little more than 2A. I...

    Charging a 12s2p pack 1s24p

    This has probably been discussed but I am not sure what to search for to find an answer. Is there any reason you cannot charge your entire Lipo pack in parallel at 4.1-4.2V in one giant 1s pack essential 4.2V 120ah wouldn't this lead to a balance charge every time? I realize you would need a...
