Right orientation for charger?
Posted by Positron0105@reddit | ebikes | View on Reddit | 14 comments
I just got a 2A battery charger and I noticed that the power supply has this symmetric connection for the wire that plugs into the wall. Is there a right/ wrong way to plug this in, or does it not matter? I’m asking in the spirit of being cautious because I don’t want to experiment when I’m charging a 52V battery lol.
Thanks

How have you gone this far through life and not encountered this type of power cord yet.

As I said before, I was being extra cautious because this is my first time handling a high-voltage rechargeable battery :) Thanks for your help!

Does't matter for AC. But there are exceptions to the rules, for example, gas boilers and so on. In any case, read the manual :)

Hey unrelated question but do you perchance know where you got the charger from? I’m trying to look for a 2A charger too and I already have the same one but I need it to also charge my other battery at the same time

I got mine off Amazon

Bought the battery and charger from JohnnyNerdOut.com

Thank you! Unfortunately it’s currently out of stock Thank you however

Both are right

It's like USB.. plug it in, doesn't fit. Flip it over, still does not fit. Flip it again and it does.
It's a quantum thing.

Either way. It's smart enough to know which is which and handles it fine.

It's not even smart, it's just AC, alternating current. It pushes back and forth, rather than travelling in a set direction. You have a 'load' wire and a 'neutral' wire, but when they are run through a circuit, the 'load' and 'neutral' both push and pull in phase equally from both ends.

Thank you!

That's the AC input for the charger. It doesn't matter which way you put it because the Current is Alternating (AC). This means the current 'vibrates' back and forth, and the 'direction' is not important.
For DC (Direct Current), the current flows only in one Direction. So for the DC side, the output that goes into your battery, it is very important that positive output goes to positive input and that negative output goes to negative input. When this is necessary, the plug will be made in such a way that it can only be plugged in in one orientation.

You are plugging an AC wall outlet in and getting DC power out. I guarantee you that it is being rectified and does not matter which way it is plugged in.
