Duralight A123

[mini73]

I have a 2300 A123 battery with 2 JR leads and the charge lead on it. I was wondering what switch to use with it. I bought a spectrum dual input and output switch (2 wires for input and 2 wires for output) but I am thinking of going with just my MPI switch that I have already due to not being sure how to hook the 123 to it. Do I need to plug in both JR leads into the receiver? I am using just a single A123 2300 on the receiver, 1500 Nimh on the ignition, and this is for a 25% airplane. Need to know what switch to use and how to plug it in the receiver. Just trying to keep it simple with the things that I have. This is confusing me alot. Thanks in advance.

Which receiver do you have?

Sure you can use your own switch. Plug the battery to the switch (btw, use black connector on the battery not the yellow) then connect the switch to receiver.

Just like a normal battery. The yellow lead on the battery is for charging.

Hope this helps,

Thanks for the help. That is the way I have it and thought it was supposed to go. I guess the Spectrum switch is the thing that was confusing me. It has 4 leads coming off of it instead of the normal 2. I have another question. I know I can charge it through the yellow lead at 1 amp and through the other black lead at 4 amps. I have the Cellpro Multi4 charger. I made an adapter for the battery with the supplied pigtail they include with the charger. When I use this I have to charge it using the No-balance A123 setting. I have seen some people have wired the pigtail where they can use the balance setting on the charger and charge it while balancing it. I know I dont need to balance it but how would I go about doing this ? I balance most of my batteries. Not a big deal just would like to know. Thank you for your help.

I'd use your Spectrum switch. It's perfect for your setup. I assume the Spectrum switch also has JR leads on it? Just plug the switch's dual JR input plugs into the two battery JR plugs. Then take the switches dual JR output plugs and plug one into your receiver's battery port. Plug the other into an unused servo channel. You're done. The purpose of the dual JR leads on your battery and switch is to give you double the current carrying capacity which you need using the JR plugs. They are each only rated for 3 amps continuous (I have never seen that in writing though).

If your switch doesn't have the JR leads I can see how you would be confused. Post a pic if you still need help.

PS: I have hear lots of failures with MPI switches. I would stay away from those.

Yes the spectrum switch has JR plugs on all the leads. I have seen on here that this is done but was not sure if that is the way that I should do it. I ordered the A123 with a JR plug on it so it just plugs right in to the switch. I have both leads from the A123 going to the switch and the 2 leads from the switch 1 going to the batt. port and the other going to an open port on the receiver. One more question. Is it ok to put an servo extension lead on the yellow plug to a plug holder through the fuselage to charge it? Or do I need to take the canopy off all the time and plug my charger directly to the yellow plug coming off the battery to charge it? I do not have to unplug anything from the receiver to charge it do I? I know that I have alot of questions. Just want to make sure that I don't screw anything up.

Sure , you could plug a servo extension lead through the fuse. That would work. Just don't charge that battery at more than 3 amps max through that extension. It might melt the plugs.

I never charge at more than an amp on my 50cc planes.

Ok. Thats what I will do ten. Thank you for the help.
