Back about eight years ago there was a problem with VX-150's blowing finals. It was thought to be when on high power and the car charger. I tested my VX-150 to see what voltage was needed to both put out full power and charge and measured 8.9v. I then modified my car charger to 9v. I use that same charger on my FT-60R. I have checked and it does put out full power at 9v. Battery charge seems to work as well.
You can read about it at:
Now as to keeping the battery from overcharging, I have a simple solution. If you cover up the terminal in the lower corner of the battery compartment it doesn't charge. I keep a piece of paper in there that I just slide over the terminal.

With a battery pack attached, that would not allow maximum transmit power.
Supply Voltage: Nominal: 7.2 V DC, Negative Ground
Operating:
6.0 ~ 16.0 V DC (EXT DC Jack)
11.0 ~ 16.0 V DC (EXT DC Jack with Charging)
