CG that is exactly what my plan is! Thanks for all the advice.

I usually fly in the 100 acre field behind my house, so I wanted an AC cycler and ordered Hobbico Accu-Cycle Tx/Rx Battery Cycler.

I have the FAAST 8-ch radio but only need 4 channels for my H9 Arrow that I fly, so I have pleanty of slots for the 2nd battery and voltwatch. I have not seen a voltwatch in person, so I just hope it is not too bulkly.
