Hello All, on my DIY project have all components and donor frame assembled. QS Motor QS273 72v 5kw hub Sabvoton 72150 controller 20S12P 72V Panasonic 32BD 38.5ah with 100A BMS Everything connected except the battery to the controller Do I just connect battery and start programming? Do I need...

Still reviewing choices. Found this info on 18650battery.com Brand Type Amps MaH Cost (S)72V P40ah) cells Cost Cont Amps LG MJ1 10 3500 $5.99 20 12.0 240 $1,437.60 120 LG M26 10 2600 $3.49 20 16.0 320 $1,116.80 160 LG HE2 20 2500 $3.99 20 16.0 320 $1,276.80...

so using 50% more than the highest "rated pull" of 150A would be a BMS of 225A or more, am I reading that right?

They have come back and suggest now a 100A BMS for a 5kw motor and a 50/150 controller.

I have a QS 273 5000W hub kit coming tomorrow. The controller is a sabotvon 72150 reportedly 50A continuous and 150A peak. I'm having a battery built at 72V 40ah with the LG MJ1 cells. (Unless they are crap - please feel free to comment). The builder 'Unit Pack Power' is open to changes but...

on voltaplex it seems: Panasonic Sanyo GA's are 3.6V 10A 17.5A peak and a 2.9C rating LG MJ1's 3.65V 3500 mah 10A 12.78A peak and 2.86C so both pretty similar LG HG2's are 3000 mah 20A 35A peak at a 6.67C rate as are the Sony VTC6's

so the hub kit is on it's way and this is what I know so far... QS Motor says: Continuous Battery Current 70A Peak Battery Current 120A Peak Phase current 280-500A Sabvoton 71250 controller: 150A Battery 350A Phase controller Battery will be 72V and 40ah. Can have it made with Panasonic PF...

Hmmm, so how would I know the difference? What information would be provided that would give me a clue?

so how is it that the supplier can recommend a 26.1 ah pack as a match? that's more like 20S7P not 14 in parallel?

Have a 19" hub kit ordered and being delivered. It is reportedly the QS 273 5kw matched for 72V Sabvoton 72150 controller. The supplier suggests a minimum 26.1ah battery to have a max of 100km/h (occasionally, but not likely often) and no idea of range. There are packs all over ebay and...

ok, QS it is then. cleaning up the donor frame now and will need to construct framing to mount the battery. Cleaning and refurbishing I understand, electronics, not so much... seems like the tab is going to be closer to $3k USD than not. For $5k I can find a used Zero S ready to go, but, it...

are you saying that the 5kw NB Power would do wheelies or if I wanted more power on tap go with the QS?

I completely agree that I've made myself confused and over thinking all this. The 48V 1500W EV Global is all set and matched. Like "some" of us, now that this one is done thinking already about the next. I picked up a 1980 Sachs Prima G3 with a non working 50cc motor. stripped it down to the...

Okay, I'm starting to feel like I understand a little more. next question is, 3000W, 4000W, 5000W, 8000W..... If I'm going to limit myself to 72V and they can all run at 72V what would one actually gain by going up the ladder to 4kw or 6kw etc.. On the QS site I see that they recommend...
