Re: Vector. New 5.4 kW ebike from scratch.

Wow it seems like everyone is getting the frame. I might capitulate and get one myself. Seems like a good deal, though I would like it with a Fox shoxx fork, rear suspension, and crank. So all I would need is front wheel, brakes, throttle, controller, battery and rear motor.

Re: Nissan Leaf Cells Test Data

John, in terms of number of cuts and wires required, I think it is the same. Your design have 4 cuts and 2 wires. Doing it the original way will also have 4 cuts and 2 wires. The only benefits I can see for your design is reuse of the screw tab terminal, which is a big plus compared to the soldering...

Re: New 2C HK multistar batteries sneak peak (Double down)

333Wh/kg when the best 18650 energy cells are ~250Wh/kg? Seems fishy... It's quite possible after reading this http://www.gizmag.com/envia-systems-record-lithium-ion-battery/21653/ Maybe this will force the 18650 producers to step into Li-S chemistry. If you read up on envia, they turned out to be ...

Re: Who else is in the 5,000 miles or more in a year club?

7600 miles so far on TC-80 over 1.5 year period though I had about 3 months down time due to spoke problems. I easily do over 5000 miles per year even if you factor in the few rainy days in the year I take my car. Batteries are showing some kind of wear, but it should still be good for many more mil...

Re: Turnigy Multistar - lightweight 10C cells

The capacity between 4.2 and 4.1 is about 800-900mah. So thats what you loose by under charging the battery. Wow! For a 10Ah pack that is 90%. Kind of hard to give up that 10% capacity just for the sake of longevity. But again it all depends on what your usage is. Most people running lipo usually b...

For the puncture proof thing, get inner lining, thicker tube with slime inside of possible and use double rim tape. Also make sure you put them on properly. Sometime there can be a pinch on the tube and that can be the cause of the flats. Have you tried these ideas? Curious as to your experience. •...

Big apple do wear out faster if they are on the rear. I put mine in the front for grip and they will last probably over 20K miles. I have 7K miles on them already and they look bearly worn. I run maxxis hookworm on the rear and they last around 4-5K miles on my setup. For the puncture proof thing, g...

You are comparing different purpose battery. Allcell are used for low power reliable high cycles safe high cost scenarios. Hobbyking is for relatively low cost, unsafe, compact, DIY, unreliable, low charge cycles scenarios. What I would use HK lipo on? An experimental quick setup, potentially high p...

It is definitely NOT 3.5 per cell unless it is LiFePO4. And even LiFePO4 idles around 3.2V. So I don't know where the previous get 3.5V per cell. For RC lipo, I recommend storing in cool area at storage voltage for prolong storage. I would recommend between 3.85V to 3.9V per cell for Lipo battery. B...
