how many times do I need to repeat this?
I am so confident it would have exploded or done nothing if not wired right
because theres only so many terminals on a bridge rectifier, and every single miswiring that is physically possible only results in: Nothing, Working, Explosion
Yes, in my head, because im capable of doing so with only 4 inputs and 4 wires
its only 16 possible combinations
My guess is still on bms
There arnt transitional states on something thats hard wired.
It doesnt matter.
Oh really
Btw do you ever consider that your CONSTANT posts about how his bike was surely miswired or some shit, is likely making loius feel like complete fucking shit and you should stop it?
YES
Hes literally posted videos titled how he feels like an idiot
immediately after the fire
your NOT HELPING
infact everything you have said qualifies under NOT HELPING
So the batteries are at fault yet you seem intent on bringing up every hour how he must have miswired it
do you not get how that could be pissing people off?
please go draw a wiring diagram where the batteries are somehow 'harmed' without instantly exploding upon connection
and what, it just sat there for 2 weeks shorted with 0 protest, and louis never noticed the huge spark when he shorted it?
correct so you should probley just move on.
I never said I was confident in the BMS, just the wiring.
And yes, it was very likely to be BMS, misassembly of the pack at the factory or puncture
Since BMS also covers everything electrically/etc: Overvoltage, undervoltage, shorting, over current, overheat
you'll have to get a cell from his new pack
I don't think flame roasted li-ion retain optimal charactistics
or are recommended to be shipped
Guys chill out
I think it‚Äôs worth investigating the cause instead of making assumptions
Because it will prevent such accidents in the future
Samsung 35E cells are supposed to be able to withstand 110 to 140*C iirc, that‚Äôs when the CID should trip
But there‚Äôs a temp above that where thermal runaway happens
If these are legit Samsung cells, the pack must have been really hot
Akbar: except hes not investigating, hes spouting the same debunked theory over and over.
Requesting to test a cell, thats investigating.
Yes Ik but I think he‚Äôs thinking out loud rather than making a conspiracy theory
miswiring theory just.. doesnt hold up.
Mainly on account of him driving it around
Ever watch air crash investigation?
We need to do one of those for this
We care but this time add proof
XT-90 was backwards? Fine
But explain why that only caused an issue later and not straight away
Also, got a link to the follow up video? I can‚Äôt find it
they are undergoing negotiations with aliexpress or something
or UPP
Ah yes
There‚Äôs some Chinese battery sellers offering $2m global insurance with their batteries. I wonder if they would actually accept claims or is it a scam
I doubt it‚Äôs fake cells tbh
@Deleted User what XT connector was backwards? The stock bafang controller that I have not plugged in for a year-and-a-half? Where do you get this retarded s***?
@district9prawn there was no smoke as I pulled to a stop
How could a connector be reversed polarity and the setup work for 2 weeks? This makes less than no sense
Apparently everything has to break for me right now. One of the spokes had gotten a slight bend which resulted in it braking at the threads. Sapim Strong for anyone wondering.
The big bend is because I had to pull it out of the wheel to continue
Larossmann++
i got a battery from aliexpress that had the battery xt90 soldered backwards
so i re-soldered the xt90 of my bbshd controller to match.
i could've corrected the battery's xt90 but... given the choice of risking shorting wires while working, I'd prefer to work with a discharged controller's wires than live battery wires
@cnrd dang don't see too many broken spokes with sapim strong
@district9prawn it had a small bend just after the nipple, so I think it broke from way too high tension (Correct tension + bend = higher tension as it slightly shortens the spoke)
with a rear hub motor, or just a heavy rear-end on the bike, make sure that the crosswalks you‚Äôre going through have a ramp on the other side and not just a curb one one side and ramp on the other for some reason. why? well let‚Äôs just say my 26 inch rear tire has a 24 inch tube in it now
wuh woh
what happened
wanted to cross street. there is a crosswalk. there‚Äôs little ramp to get down curb on the side I was on, like you would expect at a marked crosswalk, but the other side was just a curb :\| didn‚Äôt notice until last second, jumped off pedals before hitting curb to reduce weight but the heavy hub motor and battery made that effort pretty pointless, tube got pinched and popped by the tire due to the impact to the corner of the curb. got to push the bike back up the hill except not really because I could just throttle push it :>
rear wheel somehow?
oh right
Ouch.
I lifted up the front wheel
what tire pressure where you running?
no clue lOl
Probley too low.
run 40psi+ assuming MTB tires and you won't get flats climbing curbs, generally
warped rim, yes, but generally not flats :p
I don‚Äôt think tire pressure* would have mattered. Slim tire, very very hard impact
It was just the rear tire because it was so heavy, front was fine because I bounced it upward before it hit the curb
Unless you where doing 30mph, climbing curbs is doable.
I have the cheap stock tire
I used to do it all the freaken time as a teen till I wised up and stopped wanting to get my rim trued all the damn time
on normal bikes it‚Äôs fine but my ebike‚Äôs rear end is veRy heavy
and id climb curbs riding the bike
sometimes even sitting down lol
(don't do that...)
ew
seriously, tire pressure is what saves you from pinch flats on impacts
doesnt matter what tire
doesnt matter what tube
only slightly matters the diameter of the tire
pressure is king
In that particular instance I‚Äôm not sure, it was a very big impact, but my typical intuition would say yes to that otherwise
I love pressure
Its not an old curb, those sidewalks were put in a year or two ago, it was a tall and sharp curb
There‚Äôs a lot of factors that went into it
But I‚Äôm not certain that higher pressure would have helped me there
Much more certainly with a different tire/tube that can handle such pressure without potentially popping on impact anyways, though
I know
I know the kind of sidewalk of which you speak
for I have encountered its brooding walls before
standing tall like the cliffs of dover
a white cement monument to man's hubris
for thinking he could ride his bicycle over the streets and sidewalks of this wretched city
I've glimpsed such an adversary myself
