[NSRCA-discussion] Iota 55 power supply questions

Tue Sep 29 03:15:21 AKDT 2009

I have seen banana jacks rated for > 20A. I will try to find a link when I get a chance.

Of course, you could wire them with Deans connectors as well.

Just to add something here, most banana jacks from Radio Shack are rated at 10 amps and that is light considering the charger running at 5amps output into a 10S pack will be drawing 22-25 amps from the power supply. And if you use the Iota as a battery charger for a deep cycle some time (it's other designed purpose), it will output up to it's rated current (55amps) if needed, which will make your banana jacks into a melted blob.  Don't ask me how I found out....
I do use banana jacks and found some rated at 15amps which work for the 22amp charger current ok.

The Iota only has one positive and one negative post. I cut two strips of K&S brass about ¼ wide, .090 thick, and two inches long to make two lugs (one positive and one negative) similar to what you plug into a typical 110v wall outlet. On one end of each of those lugs, I soldered the wires directly from my chargers, pos to pos and neg to neg plus an additional wire for an auxiliary banana plug outlet. Then I put heat shrink over the wires and solder joint so there was just enough bare brass showing to insert into each of the outputs from the Iota. The Iota has set screws that clamp down onto the brass strips. Works fine. When you get your Iota, this explanation will make sense. If you want a more “flexible” setup, you could go with all banana jacks to facilitate plugging and unplugging your chargers as you choose. If I had to remove mine for repairs or whatever, I’d have to unsolder the connections. Haven’t had the need so far with either the
 1010’s or the CellPros.

Thank you Mr. Mueller!

Question, does that power supply have the dual outputs on it to allow me to hook two chargers to it? It is really convenient to be able to plug banana plugs right into the power supply as I currently do with my Pro Peak. From the looks of it, that is not necessarily designed for "civilized" hobby use. I am looking for something that can power two 1010C chargers with reliable clean power that I can just plug right into, or "Idiot Resistant" as my momma would say.
