Glenn, your advice has been incredibly helpful! So I'd say you are absolutely right about figuring out rpm before ordering parts. These cheap motors just have such a wide range (4900 rpm continual, 5900 max), that I'm not really sure they are dependable figures. It seems kind of moot though...

Thank you Glenn! I appreciate the response!! It certainly helps, but I am not quite grasping all of it. Are you suggesting that I... 1) use the 60v motor with my QS 80 amp controller along with 72v lipos, or 2) that I use the 60v motor along with the cheap controller it comes with, paired with...

bummer no responses. Ugh back to reddit

I already have an e-bike, so I am craving a 4 wheel kart build... I have a little kart frame here, and I only want to go 30-35mph. My plan is to buy a Vevor type 72v brushless motor kit ($250 on Amzn), then attach a 60 tooth sprocket on a live axle. I will power this motor with the 72v lipo...

The Dogman has spoken 8) Great, really appreciate the input. I know I've asked you this question before, so I am really grateful that you had the patience to respond again. Thank you friend.

Yea, thats why I kind of thought individual chargers for each pack would be simpler yet "smarter", just at the expense of a slower charging time. And thank you so much for posting those specific model links! I will definitely look at them. Appreciate the input.

The ebike builder who I purchased my qs-205 v1 kit from, included the QSYK7280 controller, good for up to 72v/90 amps. Now I thought that would be too big, but, the controller is bluetooth programmable and can adjust power output on the fly. Currently my controller is programmed for 60% output...

Well you have just thoroughly answered my question. That was more details than I was hoping for, I appreciate the response very much, thank you!

I have done all I can to figure things out on my own. I am looking for confirmation. 1) I have not found feedback from those using cheap 100w chargers to fill 16k packs. I also have seen to match ah to amps, so thast 16amp charger, which is above that one, so I felt unsure. So I asked if they...

So I have (3) individual 6s 16k mah lipo packs for my first ebike that I am putting together. I have it narrowed down to 2 options, just seeing if one is clearly better then the other and making sure they both will work. Opinions on my 2 trains of thought would be GREATLY appreciated...

Great to know, thank you for the help

Great, just the info I was looking for. Thank you!

So I am still holding off on buying my battery, but I am pretty sure I have narrowed it down to running 4, 4s lipos in series to make a 16s (60v) 20ah battery. Was ready to pull the trigger, but I am realizing now, that I am not educated enough about how to charge these high cap lipos. I need to...

So HK has a great price on the 4s 20,000mah blue Turnigy lipos, only $120 a piece. I would like to series connect 4 of them to make a 20ah 60v pack for only $480 dollars. I was set on these packs, but I'm realizing I dont know whats involved with charging this high capacity of a lipo...

Well I talked to a high power bike builder today. He has built many bikes with the QS and Mxus motors and I've seen many of his videos on youtube. When I mentioned that I wanted to use a triangle 52v battery from UUP on ebay, he told me to avoid that, as the "3k motors draw will trip the cheap...
