Am I Cooked?
Posted by Derraj_OF@reddit | ebikes | View on Reddit | 37 comments
I was looking to switch my 4 pin battery to a 5 pin without me doing any research (I’m an idiot) and assuming it would as simple as soldering the wires together.
After countless attempts with heat shrinking tubes, and electrical tape, it didn’t work. I guess that it wasn’t as simple as switching like that, and have tried to put the original 4 pin back together through electrical tape, and that did not work.
I now have a broken bike that’s sitting here (and one of my main transportations) and before I make any more moves I thought it would be best to bring the question here. Am I cooked (Please say no)?

You have 2 wires and 5 pins?. Did you test ( multiple meter continuity) which pin is energized by which wire on the connectors? If it's different on the two connectors, it will never work. Figure out which pin is actually which wire, and MAYBE it will solve your problem. Maybe.

I’ve kinda lost hope on installing the five pin, but shouldn’t soldering the original 4 pin back on the wire allow my bike to turn back on?
i_am_blacklite@reddit
Yes. But you haven’t even tried soldering them on as you posted earlier. So how do you know that it doesn’t work?
Cunhajo1409@reddit
Should, but not knowing which pins lead to what, and if multiple pins are energized from the same wire, there may be some circuitry inside that connector that's fried. Have you tried a new connector WITHOUT soldering to make sure the heat doesn't damage it? Otherwise, try finding a complete harness. Don't give up on the bike. Best of luck.

It doesn’t look like you’ve attempted to solder them together at all… so it hasn’t worked because you haven’t connected them together!
Electrical tape and heat shrink tube don’t connect the wires together…
TheSiege82@reddit
I’m confused, can you solder the wires and heat shrink?
Derraj_OF@reddit (OP)
I haven’t tried actually soldering the wires, and the heat shrink tubes can’t work because I cut the wires too short. 🤦♂️
HugePossession6954@reddit
Tendrás que hacer cortes pequeños para pelar el cable y con ello soldarlos con un cautín y una soldadura de estaño/plomo 60/40 (así la consigues, soldadura 60/40, la básica para electrónica) y con un cautín vas a pegar la punta al cable y en el otro lado del cable colocar el estaño, hasta que no veas que el cable se torna gris (supongo que son de cobre y no de aluminio) ya estará completamente adherida, puedes ayudarte entrelazando los filamentos de ambos puntos para tener mejor anclaje o solo retorcer los cables y soldar

Hear shrink tube is for AFTER the wires have been soldered. It's used to protect the connection and prevent shorts like the insulation that was stripped of before soldering (or using butt crimps).
The sharing tube is slipped on the wire before connecting, slid out of the way, then the conductor connection is made, the tube is slid over the connection, then heated. The tube should be long enough to overlap the insulation on both sides of the connection to get a waterproof seal.
Unw1shed@reddit
You've got just enough to work with. The overlap should be about 1.5 wire diameter
rvralph803@reddit
They definitely can. Slip them on the longer controller wire side.
Joomin69@reddit
Electrical tape might work
DimMagician@reddit
First of all, this is completely repairable. Don't stress.
Here's how I would do it given how little wire you have left on the connector.
You need:

This is the way.

I’m going to piggy back on OP’s questions..
On a bike with 2 batteries, the first bike is 36v 10.4ah and the second battery is 36v 14ah, which battery balancer would you choose?
A 30A, 40A or 60A battery balancer? Or potentially higher?
Because it’s a bit confusing.
DimMagician@reddit
The amps (A) is different from amp hours (Ah). When choosing the battery balancer, use the amps of your controller as a reference. The balancer's amps should be greater than or equal to the controller's amps.

Worst case scenario, just order a new socket from AliExpress or something. They don't cost much, and come with longer wires.
flippertyflip@reddit
No. But you'll have to learn how to solder.

Look at the state of your chain. Do you not have any chain oil?
Derraj_OF@reddit (OP)
I’m getting a tune up on the entire bike as soon as I get it moving again. My back disc break is also falling apart.
Reelair@reddit
These are very easy things to fix yourself. A few videos on YouTube and you can learn in a few minutes. Many bike shops won't work on these bikes, so best to learn the skills to do it yourself.
Significant-Pen-6049@reddit
Kind of curious why tried to go to the 5 pin
Cheapo soldering iron will get you back on road
Derraj_OF@reddit (OP)
Was buying a new battery for the bike, bought a five pin instead of 4, which I was told could convert.
UsernameTaken1701@reddit
Okay, in the future “convert” should be taken to mean “short cable with 4 pin receiver on one end and 5 pin plug on the other”. Surely you’ve had to adapt a USB-A thing to a Mini USB thing or a USB-C thing. Did any of those involve cutting the wires?
Significant-Pen-6049@reddit
Ohhhh ok got it. No worries you'll get this fixed
younginonion@reddit
it goes without saying to research in tenfold before chopping up your "main transportation".
"countless attempts" of what? your description you'd try soldering and heat shrinking but you havent even stripped the wires? did you make countless attempts of prayer, or....?
you need to scrap whatever you're trying to do and research XT60 cable. it is plug and play once you find the controller of the bike.
aimless_ly@reddit
If this is your main mode of transportation, you need to take much better care of it. That chain looks like you left it for dead, I can only assume the rest of the bike is just as poorly maintained.
slacknsurf420@reddit
I was gonna say, why are we in the working controller when the chain looks like that? is this EE or gym class?
Suitable-Ad3475@reddit
SOLDER THAT SHT or wear fire protective pants
rvralph803@reddit
Get AWG 10 crimps and a haisstronica crimper, some heat shrink sleeves and a hairdryer or even a lighter.
You'll be done in 5 mins.
GumballGumbo@reddit
Have you tried to pop open the black cover connecting the wire and pins?
If you can, there are a few options like:
Removing the short end of the wire from the pins and stripping the other end and attaching/soldering to the pins directly.
Or you can use butt end wire connectors that have skrink tubing on them after stripping both the short and long ends before putting the cover back on
you can also solder the wires together and use heat shrink tubing before putting the cover back on.
If the cover on the wire and pins can be opened and put back together, you should be ok.
MaxTrixLe@reddit
You have plenty to work with, if you know what you’re doing and have a good quality iron
BidUnited2930@reddit
Did u strip the wires ?
Flute-With-A-Fro@reddit
As long as the voltage matches, all you need to do is match positive and negative. Use a multimeter and check which pins are the power pins of the 5 on the battery and wire it up with red as positive and black as the negative
Middle_Pineapple_898@reddit
Did you try soldering it? The wires don't look like they were stripped and soldered....
ArmchairPancakeChef@reddit
This isn't going to help maybe for future. You made your cuts too close to the plugs. You left yourself nothing to work with on that end.
Derraj_OF@reddit (OP)
Yea I realized that after. I’m not an electrician, but I hope this is salvageable.
ArmchairPancakeChef@reddit
It has to be fixable somehow.
