- Have everything back together on the painted frame and going over the high-voltage wiring then spinning the motor. Also my power converter box broke.

hello, thank you very much for your videos, if the 72v battery is always connected to the kelly controller without using a contactor and you would only use the key for pin 7 to turn the kelly controller on and off, would the precharge system or contactor no longer be necessary?
the precharge resistor is not needed if youre not using a contactor. you dont need to use a contactor and can turn the controller on/off using the switch on pin 7. but your controller would always be connected to power. This is not so much a problem for the controller but its better practice to be able to physically disconnect your controller from power
What's the range u think you'll get with this set-up?
this particular setup - not much. only 20Ah battery here. I have ride video where I take it from about 85% to basically discharged in about 15mi. I'm currently rebuilding this bike around a 42Ah pack that should be alot more practical
TY for reply. I Subscribed😘💗Can't wait to see that video💣
@@Unacknowledged182 thanks so much! I'm multi-tasking a few project & dropping some rapid fire videos soon!
Hi from Ireland,
Great detail, I'm at nearly the same stage in my build. Mine will also be street legal. I have a 24s 1p po4 65ah battery .
How long are you hoping to get from your battery?
sounds like youre in a much better place with your battery. any chance you can link to it, btw? I think the range will be pretty low in my case - 20Ah will not get you far - maybe 35mi?
@@GaiusGarage where did you buy your battery? Im looking to build a similar bike using qs138 but with a smaller bike. Thanks
@@dixon266 I actually built this battery myself. check out the video here: th-cam.com/video/iPsxvFEz4SU/w-d-xo.html
Love your videos, you are very good at explaining things.
What contactor did you use for this build?
thank you! it was this one kellycontroller.com/shop/zjw-400a/
Why not using a in-wheel bldc hub motor instead of a mid-drive motor without chain? Guess that'd be a lil easier to have it mounted, saves time. For my project they told me a contactor is not really required and it works well without one so far.
mid drive is better in most ways - bike is more balanced, no large unsprung weight, rear wheel easy to remove and service, ability to change sprocket to adjust torque vs. top-speed. hub motor (especially on a motorcycle vs. an ebike) is not really suitable unless it's something like a commuter/road bike (no off-road). best thing about a hub motor is that they are silent and don't take up any space in the frame so there's more room for batteries. but mid-drive is the way to go imo
+1 unsprung weight - but it's hard to wrap your head around unless you're big into physics@@GaiusGarage
