Thanks for that prompt. Whew...that is a lot of thread space. I spun through most all the threads in that search.
I'm sorry for not searching first, as is normal etiquette, I was on mobile and venting. Very frustrating to get the whole family out, the kids wound up, and ending up with a dud experience. Not the way I wanted the introduction to go.
PSII is about $50. C batteries about $15. $65 total. I don't want to chase C batteries.
PSII with LIPO and charger as I read...about $90 total + connectors if necessary. And you gotta futzs with connectors and I don't understand, nor want to understand balanced charging, JST connector limitations, etc, etc.
I want one that is simple, uses a normal battery that I can keep charged and ready.
My experience was always with my astron launch controller (long gone) that you hooked up to a car battery.
I think this is the right solution for me:

With Battery is $100, and I have a norco genius that I can use to keep it charged. Simple, connectors are done, 50 feet of cord, charging is simple, no JST connector limitations, etc., etc.
Any reason NOT to use this controller? (Seems like the only other one I can find, that is of this design, is the Aerotech, but you have to assemble it, it is $115, and you still have to buy the battery).
Thanks for that. I'm convinced it was the aftermarket batteries. I'm not even going to attempt to try them again, I want a once and done solution...I think the Antares should work...I think...
