He was strong enough to not explode
Welp nice to know why the old battery would never ever balance on those 2 cell groups. Because one cell in each were brutally murdered
rip
>10 awg
>little
It sure is little when you have 150A.
2 x 10awg on a 20p pack. Kek

LMAO
the regret you will face if you don't use a torque arm
Pinned a message.
Uh what happened here ?
Good question
Too much torque and not enough torque relief
That's decently thick metal they sheared off
It's why we hammer in torque arms for 500w and up hubs
I'm assuming they're definitely more powerful 500w hubs than mine cause my 48v 500w hub hasn't done shit to my frame
...yet
Ran a hub motor with no torque arm and ripped out the rear dropout
I'm barely crawling up hills I doubt it has enough torque at all
65nm claimed
Yeah torque means that is has 65 newtons from 1 meter away from center but 1 cm away from center you have 6500 newtons of force and it is force that is applied to dropouts. Also aluminium doesn't bend but it shatters so higher likelyhood of this happening.
Dunno I've ridden this for weeks and the dropouts looked completely fine when I replaced my tire 2 days ago
I can’t believe my eyes. It broke like a plastic.
And I mean I can hold the bike in place with my legs at max power with the throttle
Gonna have to redo the bearings on my derailleur

Give me enough gearing and I will break it with a 10w motor üòõ
This might be too much https://www.youtube.com/watch?v=nFslB0AcVmM
now spin it the other way
Naw
Googolplex exists
Small update: when you buy a bike, make sure the lower pulley has all it's pieces: mine didn't had the side plates .
my bike cuts from 1200w to 0w and then back to 1200w when my battery is at the 40% mark (46.9v)
Probably bad battery that has high internal resistance and bms cuts power
Sounds about right
120$ ebay battery
He literally dented it and it has no hard casing
Of course something is wrong
oh yeah I didn't check who asked üòÑ
His battery gives me nightmares
When batteries that look safe can be extremely dangerous why the hell would you trust a battery that has so many red flags üò≠
@Black Moons Sweet I'll pick up some mt60s. But what about the display throttle etc I hate the stock connectors for them they are so bulky
Good to just wire them together?
Jst-sm
^^
@Black Moons they already got them so guess I'll be fine
JST-sm is really the defacto DIY connector for e-bikes.
(for signal wires and low power lighting)
Another thing went wrong with my setup today. My trailer wheel looks like the freaking axle and bearings (I forgot what the thing that holds the bearings in is called) somehow came out of the hub and was wobbling. Luckily
Yeah they seem pretty sturdy. I just thought thered be a better one instead of the blocky display connector
Luckily I made it home and can take a look
Higo exists, pretty compact and waterproof. Sadly it only comes in injection molded so you can only get 'pigtails' and not raw connectors.
'waterproof automotive' (.. seriously just find them on amazon) also exist with sexy gaskets and stuff that you can DIY, but they are BIGG lol wayyy bigger then JST-SM
(Higo is much smaller then JST, and round)
Sweet gonna add em to cart
But then you gotta splice it into your existing wires
and waterproof that splice
They are small wires too
Yep.
I'll use some of that self sealing silicone tape I gues
some controllers/e-bike throttles/etc come in HIGO now though, so you can slowly switch over and reduce your number of splices
I got some of those mt60 on order too
I absolutely HATE these shitty hubs the race holder or whatever it's called is so shit
Second one that disintegrated on me out of the blue
Now I have no choice but to re hub this dam wheel gah
And the freewheel was nearly impossible to get off
At least I saved that
Man I hate this
Wtf the axle spins even better without bearings in there 🤔🧐 wonder if can use it without bearings guess it would wear a lot quicker tho
I just borrowed a wheel from my other wagon
Back in business
Also my eggrider is Royall f'd . Won't even read or write the controller now and is turned on 24/7 without being able to turn off or on . So I have to make sure my battery never dies till I get a new display
Not to mention I can't see battery percentage. Thre is lines going everywhere on the screen
Guessing eggrider is the best bafang controller tho
Eggrider isn't a controller. It's a interface display. It just gives u access to all the settings and acts as a middleman for tuning.
The controller is in the casing of the bbs series
Yes I know
I made a typo
I meant , best controller controller
yeah this happens to me when I try to pull 40 amps at lower battery percent, the solution is to upgrade your battery or not pull that much power. Although I'm pulling almost 3kw, most batteries should be able to do 1.2kw at 40% just fine.
yeah all quality batteries with good cells
maybe some 1p pack couldn't handle that with low current cells
but thats bit useless with ebike
upgraded my bat
it's in the mail
em3ev shipping annoying at
Yea it's just how shipping from China and other countries work. U get the departure. Then nothing till. It arrives in ur country. If it's shipped by cargo ship it can take a while
yup
which one? 25amp bms or 15amp bms?
60
i think
yeah
triangle one?
super shark 52v
sweet
im excited af
it's taking a while to
tho
