Hi Bill, Replacing batteries, or switches, or anything regularly, especially if the original components in use are healthy, is full of danger! The odds are the replacement will fail where the perfectly good component pulled out has proved already it's integrity.
Every time you introduce a new component, like a battery pack, you have now introduced an unknown. You have no idea if it is put together correctly, the crimps are good, all the cells are operational to the same degree, etc. Folks have employed this logic of replacing their batter packs every year without exception, only to experience a crash because that brand new part failed. You are best to stick with components that have proven themselves to function properly, especially after many flights. Only replace battery packs when they have reached the end of their useful life (whatever that may be). As to adding extra points of failure, I disagree. If something fails on either of the separate packs (including a short), the other pack stands an excellent chance of continuing to supply PWR. The alternative os well, no control.
