Controller for my bafang

[giraf0]

Hello, I was trying find some info about controller for my bafang but without success.
My question is what kind of controller should I buy for my bafang 8fun 350W/ 48v/ 15A.
Because I found couple of them but all of them are for different voltage or different power or different electricity.
I found on this link this two:

http://em3ev.com/store/index.php?route=product/product&path=46&product_id=188

but first one is for 500W 36V and 25A
second one is for 500W 48V and 18A

then I found on ebay another one

first one is for 500-700W/ 48V/ 25A

second one is for 250-350W/ 36V/ 18A

I didnt find controller for 350W /48V / 15A what I have. Can you tell me where should I order the controller or which one should from the links.
Thank you for any suggestion!

The 18A and 15A are the same, and so is the motor. The only difference is the setting of one of the parameters in the software. You can buy a cable to program the 18A down to 15A if you want.

Which Bafang motor? They make a three hub motors: SWXH (250w), BPM (350w), BPM2 (500w). They also make a BBS 01 and BBS 02 mid drive motors, which have the controller built in, no need to buy one. If you have a BBS, the answer is NONE -- you already have a controller. Unless it is broken, which you did not say. If this is a BBS, forget the rest of this post.

So, which motor?

Let's assume a hub motor. Since you mention 350w, you could have a BPM hub motor. So the controller should be rated 48v, and at least 350w.

The following controller on ebay meets your spec, but is barebones in terms of features. It works well for limited power and features and is available from a US shipper.
