I assume that you are not using tool batteries. If you are building up a battery, 14.4 volts is pretty common. If you put 2 7.2 volt packs in series, you will then have 14.4 volts. You can charge both packs at the same time with a smart 14.4 volt charger. Please make sure that both packs are equally charged before you put them together.

I do built-in batteries on all of my installs. Do you already have your radio and sound unit. If you are going to use all of those pieces, there might be better alternativves for what you are doing.

My point was that if you are going to spend $300 on radio equipment, you can do better that Aristo, especially if you do not have your sound unit either.

I install and use AirWire.  Street price is right at $300 for 1 receiver and a transmitter.  For sound, you can easily hook a DCC compatable sound system to it.
