Im a good 10yrs into a build, thats mainly the result of me giving up every couple years thinking "ill see if i can get that controller working this time. So, now i want to ditch it and get something that actually wont give me any grief. Must haves: 5000w Minimum capacity current motor is 5kw...

because at times it worked at other times it didnt, and the batteries seem to be fine on anything else. and now it seems to work, so, im trying to get controller programmed now to set appropriate limits

alright, theres something to this so i disconnect it and reconnect within a few mins and its good, if i leave it sit for a while, it wont run, i just disconnected battery while it wasnt working though, ran the multimeter over every contact on the back, shorting as many points as possible, and...

oh dear... im not sure if something is disconnecting/connecting incorrectly, or if im.inadvertantly triggering a switch. i draged the multimeter accross the bottom of the board checking for continuity between the groups of transistors, then i touched some random points just out of frustration...

hold that, i spoke too soon, disconnected battery, went out, came back, connected battery, moved nothing, and no response again... somethin wierd goin on here, battery reads 1v again when connected to controller

ok so strange. i got the shits on with it gave it the fonzy and banged it against the table in rage, and boom, motor works and it measures 68v accross the battery while connected. clearly the controller has been shorting :/ ok, back to bluetooth issues!

each 12v pack has its own bms, and individually read 13.8v when disconnected. I did wonder if perhaps low voltage cutoff was an issue if it was factory set to say 72v, only it did work prior (granted there was only 30 secconds of testing), which suggested it must be something else

Following this post, the next day I didnt even get lights on the bt module. power velocity responded on thier own forum and said to chop off the bt module, but that didnt work. measuring the voltage accross the batteries disconnected, I get 66v. measuring across the batteries whilst connected...

Yea, powervelocity have been unresponsive so far, though, it hasn't been *that* long since I tried to get this show on the road... however, even to the PM i sent them 3 years ago asking for a tracking number April 18th 2017 i never got a response, never heard a peep since that date. but, I've...

one step forward, two steps back. yesterday, had motor turning and bluetooth connecting. paced up, pulled off batteries, popped them on chaerge, recconnected batteries today, and nada... neither, motor nor bluetooth hypothesising that maybe i pulled the ignition wire or something i pulled the...

bummer, had no clue. I assumed the motor would only suck down what the controller would let it (which i guess is moot when the controller isnt working right) So, given that there's nowhere near enough room to fit 40x packs in there for 300A, would it make more sence from a *not blowing anything...

Perfect, thank's so much :) I added an extra battery pack to make it a 56v setup with 5x12.8v in series based on your observation in my last thread, hopefully this will help with that anticipated problem? What would you suggest is ideal here? should I be running twice as many packs so that I...

I've tried a few combos and not sure which one is right, cant figure out if one was smoother than the other, so not sure what is the correct way of wiring it. These are the combos I tried and the results I got MXUS 3000 - partially worked, seemed to groan/jolty Phase Y-y, B-b, G-g Hall Y-y...

Settle down johnnie, I didn't say "Pay in exposure" (though, I am currently working for exposure myself), and I didn't ask for a "volunteer" I DID say I'd plug the shit out of you if you can do it PROMPTLY. I DID ask who can get it done quickly and cheaply without killing my budget. Nowhere did...

i sent an email to power velocity and asked on thier own forum. I actually purchased the controller off this site, so pm'd the seller here too, but given the covid restrictions im not anticipating any fast replies from anyone not currently working. I've tried using a couple of android phones...
