Less components means less problems with bad components, less solder joints that eventually break with vibration, all of this is better than good. I run same setup, on-off switch for both batteries, usually only one of them online, except when getting my engine (turbo) out in case battery runs out of juice right then. Zero problems ever. Glider came out of factory with both batteries wired parallel btw.
