What do you mean by wrecking them?

If you're using a 2s lipo as a receiver pack you *should* be running a regulator and not plugging it straight into the receiver.

Are you over discharging them? You shouldn't be pulling them under 3.7v/cell with no load on the pack.

It's not the battery that's the issue, it's that you don't have anything to protect the battery from being over dischagred and you're also giving too much power to the receiver and servos (unless they're all high voltage).

If you want to run a 2s lipo for an RX pack you need a regulator:
