I'm glad to hear it's working now, but my point was that you aren't completely sure that you've fixed it. Let's say the issue is actually a connector that's a little too loose on your switch. You unplugged it and plugged it back in, creating a new good connection, but the problem could come back in a few weeks due to arcing causing corrosion on the connector. Or if you have a servo that's drawing too much current this new battery may be able to handle it and prevent a brownout, but eventually the servo will fail or you'll get a brownout at 1/2 charge when you shouldn't. That's why I suggested that you still do some diagnostic work to be sure you identified the problem correctly to begin with so you don't get a surprise later.
