I have 48v 5 ah charger and now my new replacement bike came with 48 v 2 ah charger with 3 pin? can it get an converter from 3 pin to one RCA type as to use my old 5 ah one pin charger?
can it get an converter from 3 pin to one pin as my old charger is 5ah?

Pictures would be helpful, but absent that, maybe you can identify which connectors look like what you have. My guess is XLR, which are frequently used by cheap chargers, and the DC Jack connectors.
Connectors - Learn
There are lots and lots of connector types used in the ebike industry, so many that it would be a very tall order to try and list them all. In our business, we focus just on aftermarket conversion kits and have tried to keep the connector styles down to a well chosen minimal set. This page...

FYI - Ah is a current over time unit of measurement, usually used to describe the capacity of (ebike) batteries, Wh being the corresponding energy unit. Chargers don't store energy and just provide current at a certain voltage, so rating in amps (A) units.
I don’t recall ever seeing an adapter like that already built. You will probably have to make one yourself. Be sure you know which wire is positive and negative before making.
I moved your thread out of Forum Rules and Features (what a wierd place to post it) and moved it to the Battery Technology forum instead since it a question about a battery charger issue.

I moved your new thread into your old one for the same thing. Please keep all your posts about this in this thread so we can help you.

Site a bit confusing thanks for your assistance... getting me to right area.. any solution I can buy for the conversion plug?
Highly unlikely that you’ll find anything.
You’d need to know the names of the connectors to be able to search. I haven’t come across that particular 3-pin plug and have no idea what it’s called. If someone else knows, that would be very helpful to you.
The other plug is not RCA, it’ll be what’s commonly called a “DC jack” or “barrel connector”. They come in different diameters.
The third pin is probably just connected to the negative, but it might carry a temperature signal from the battery management system that shuts the charger off when high battery temperature is detected. In which case you should persist with the new lower amp charger, despite the slower charging.
If you’re not keen to splice cables, it’s not possible to help you any more than this.

If you look at the link previously provided, you'll see one there that looks similar, but not identical. If it's the same dimensions it might work; I recommend asking the company at that link if they have seen your connector and if they can make you the adapter you are looking for.
Keep in mind that the polarity and wiring must be correct, so they will probably have to have you test voltages with your multimeter to make sure you get something that won't blow things up or start a fire.
