Hi,

I was wondering if anyone has done any research on banana plugs and posts for connecting chargers to a power supply?

I wasn't sure if certain plugs/posts can only handle a certain amount of amp draw through them?

Basically, I am looking to buy a plastic project box, put a bunch of banana plug receptacles in it, plug my chargers into that, and just have one pig tail that goes to my power supply.

Standard size bananas should be ok for charging, but dont use them if you are going to pass more than 7 amps through them.

i use standard ban plugs from the local elec store. works fine. i think the rating on them is no more than 8-9 amps.

Hey Rich, if I would have known, I would have had you take a look at the system I made. I set up exactly what you are suggesting.

I went to a an electronics store and bought a black box and some banana plugs. I've been using it like that for a couple years now and it's still working great. If I remember, I'll take some pics for you, but I'm sure you already have an idea of how to set it up.

Send me pics anyways, if you don't mind. I always like to see how others do things. :)

Muchmore has one that they sell that is pretty cool, but they want like $60 for it!

Pfft! Mine maybe cost me $15. I guess it would depend on how many plugs you want. I'll pull it out tonight and post it. Check at rcxxx, as I don't come here too often.

i made about 5 boxes and sold them.. not profitable in anyway.. and time consuming :P

car action has a cute article.. http://www.rccaraction.com/articles/powertools.asp

Thanks! I think I'll look into doing something with the power pole connectors b/c I already have those on most of my chargers. I just need to figure out a way to mount them in a project box. :)

Rich, this is how I did mine. You can see it's fairly simple. I didn't take it apart, but if you were to look inside, all I did was solder a single wire across each positive plug and ran that to the positive pole on the outgoing. I did the same thing with the negative. The outgoing poles that plug into the power supply are just steel bolts.

I've been using banana style plugs since the early nineties on all my power supplys\ chargers thu the years>The ICU brand plugs will handle most all the current you need to run chargers,com lathes,etc,The ICU's are stackable as well so you only need one +\- off the power supply,I've stacked 4 chargers and my lathe off one output on the power supply with no voltage drop or current loss,the only issues would be motor run\amp draw,with a bunch of chargers going all at once if the power supply didn't have the amperage output to run all.

Ennjy-Nice box.

Thanks. Yeah, so far I don't seem to be having any amperage issues.

I just built one this wek as well... works great.. i also got one of the black boxes, and made a power base for my lathe.. Put in a 4 cell pack, bolted the lathe to the box, and added a switch.. and two post out the side for charging.. no more hooking it up every time i want to use it. Just rmeber to re charge the battery every now and then..

I was wondering what some of these store are that you guys are getting your supplies from. I got some stuff from Radio Shack but they dont have everything I need. Thanks.

I ended up buying a bunch of the Anderson Power Poles bulk off the net from hamstop.com (100 pair for $80 shipping included). I also purchased this distribution box:

It's pretty nice -- all connectors are soldered onto a board so I figured it would be better than anything I hacked together. It was $36 from Hamstop.com.
