Need help identifying a controller built in to battery tray.

[snowlover4u2005]

I have this ebike I purchased from Temu. The controller got wet and the display will not come on. I tried a new display. I would like to fix this.
I cant find the right battery tray with the built in controller. 48v 17AH battery that appears to be good. Motor and controls test okay. The display is blank. Tried a new display already It is not a KT style. Hopefully someone knows where I could get parts for this. The bike is like new and was really fun, fast and the battery lasted all day at burning man. PLEASE help me. Thank you Dan

I would like to use my battery and charger with a different controller. Not sure how to find the manufacture of this battery. I'm okay purchasing a cable to make it a KT setup. Just not sure on the best option to go with. I can not find any makings of use on the battery.

A lot of people use similar cases and connect their controllers to the existing pins on the battery cradle, It's tough to find one that fits a specific case. I bought this 22A KT controller cradle from topbikekit.com and the cradle was the wrong size. Supposed to fit a Hailong 1-2 battery cradle, but was delivered with a Hailong-2 cradle.

It's nominally 140 x 61 mm to edges. Is that the same as your present one?

Otherwise, I'd buy something like this stand alone 22A sinewave controller on this page for $43. The connectors should fit. You'll need a KT display though for either.

My battery has the flat blades.

 

[snowlover4u2005]

Is there a battery tray conversion or cable I could add to use the same battery. Not use the controller in the tray? I cant believe this is SO unique that no else has seen it. I would still like to ride this winter and have the E helps the fun factor.

Blades are easily changed,

What do you mean by blades?

How would this help me? I need a new controller PCB. I do not know. Ready to sell it and start over. Thank you for the reply.

I put up the pic so you could see if this 22A KT controller would fit your case. You can always change the blades, or just solder the leads to the ones off your old controller.

His old controller has only 2 terminals connecting to the battery,..

The KT controller you posted has 3 smaller pins in the battery connector,..

Do those three pins need to connect to anything or do you just snip the wires, and only connect the heavy gage positive and negative battery wires to the blades?


EDIT:
Your link doesn't show a battery connector.
I guess you put that battery connector on?

 

[snowlover4u2005]

I was having a senior moment. I get what your saying now. Its worth a try. Thank you again Dan

I found this Hailong 1 controller, if it's in any way helpful?
I don't know about Hailong or HowLong they are.

Actually, the controller @harryS linked to is a 9 Mosfet controller.

The one in my link is a 6 Mosfet controller, and is probably smaller?

It should probably fit in either Hailong case.

 

[harryS]

It's the aluminum casing that matters. I probably bought my 9 MOSFET from the 6MOSEFT vendor too. It has to fit your existing cradle. If the aluminum case fits the cradle, then you buy the controller along with a KT display which the OP would have had to do anyway and it's pretty easy, Might have to get a 4:1 handlebar cable, if they are not universal between Lishui and KT, but I think they are.

Is it worth the extra cost to buy a battery cradle controller? Simplies the job. You have to buy a case for an external controller anyway, and locate it on your bike. Less clutter. That is why I bought mine, but it didn't fit the battey I was already using,

What about this ??
A complete HaiLong 1 carrier/controller replacement,..

I'm thinking it would be a plug and play replacement?

https://a.aliexpress.com/_mtCiVzd

And if he needs a 4-1 they have 3 sizes available and 4 sizes of motor cables.
But I don't think the OP would need them ?

I still don't know what a HaiLong 1 or 2 is, but I think the HaiLong 1 is the 15 amp version and HaiLong 2 is the 22 amp version ?

 

[harryS]

The Hailong 1-2, and onward is a real can of worms. Maybe Tomjacz could explain the history, but that is why the OP is in this dilemma, I have four of these cursed downtube packs and none of them fit each other,

 

[PCeBiker]

I've got 3 Reention Dorado batteries that are interchangeable with both my e-bikes.

I'm glad that I don't have to try and figure what you've got going on.

I only needed to buy the proper length of two battery choices.

Even my newer battery type is going the way of the and everything is switching to proprietary internal batteries.

I'm not sure if this product from Grin Tech would work, but here's the link:

🇨🇦 Baserunner - Grin Products - Product Info

The Baserunner is a slim profile field-oriented motor controller that fits inside the baseplate of popular downtube battery packs. This product is based around ASI’s BAC355 controller platform ,but is configured and connectorized to be much easier to wire up in an aftermarket ebike.

This is my first Ebike so I am not very versed on them. I appreciate your input on this issue I'm having. I tried order the kit and they canceled my order. Said it would not fit my battery. Not sure if it is a polly or Hailong? Its very close looking to both.
