Hello, I'm building an escooter and battery. Qs260 v4 8000w hubmotor,and spim08hp cells for right now to get me started. My question is about wiring a common port or separate port bms for charging only. I have a wiring diagram for a separate port bms for charging only. Just run a 2nd wire from...

Also,if this is correct,can I wire any bms like that? I'm using 20s 1p right now but once I wire this correct,I'm doing 20s maybe 4p or 5p.

Actually there 12c not 10c,if that makes a difference. So I would be running Them at 6c peaks and 4c constant. Maybe I can do 5c and 3c to start out with and see if they heat up at all

Ideally I would get something bigger but I would need to spend about double for 21700 or lifepo4. Plus I don't know if I could wire and program bms. And buying a pack pre-built is like 3 times as much as these lipos

I was thinking of 1/8 or .25 inch spacers between each battery because they will be stacked with only the sides exposed

No,maybe 2-3 times a week

Hello, can I ask a question about lipo wire guage? I've seen alot of mixed answers on this. Im buying 5 of the turnigy 10c,20 ah, 4series lipo. I'm replacing the xt90s it comes with,with as150 connectors. Il be connecting them in series to get 72volt nominal. I'm putting the as150 directly where...

Hello qs,I sent u an email a couple days ago on your website. I'm interested in the 12inch, 260, v4, 50 or 60h,7000 or 8000watt. I have three 6s, 20ah, 12c, lipo batteries for 66.6 volts nominal and a 72volt 300 phase amp kelly controller(more like 100 amp). I'm upgrading to two of those 66...

I'm going with the 8000w 273,not the 12000,too much for the 12000. I looked at some of the specs and it looks like it's actually the qs273 that has a 277mm axle and the existing hub on the scooter has a 272mm axle. But the dropouts are wider on the existing wheel. I think this will be a little...

I was thinking about getting a qs273 8 or 12000w 72 volt. Instead of the fat tire. I will still have a 18 inch tire so it will match the front, but it will be a little thinner. I'm looking for power. The axles are almost the same length ,qs is 275mm and fat tire hub and frame are 277. But i...

I know there is a couple signal wires(12v 5v)Is that where the light goes to or does it go to the brake lever or?

O I see now that's the brake lever. What about the brake light tho

Thanks and where does the brake light get connected,I see that little doorway looking thing on the wiring diagram,what does that mean? Where would the rear brake light go to?

So I'm converting a fat tire scooter from 60 volt to 72 volt,but the biggest qs motor is an inch or 2 short for the dropout. I think qs 12000w said 150 dropout and 275 total axle length and my scooter is 255 dropout and 277 total axle length. So there about the same length but the dropout is...
