Brian,
If weight is not a issue-yes you can use a bigger size pack-but keep the SAME voltage example: 6 cell 1400mah pack or a 6 cell 3000mah pack-the VOLTAGE remains the same-just like when you replace your car battery with a LARGER size one-BUT they are ALL still 12 volt batteries.Just make sure the pack you use is NO more than 6 cells. Maybe these newer 6 cell 1250 packs have lower internal resistance so they can pass more current and get less voltage drop-lets say a 30amp load for 10 secs. and the voltage still stays at 7.90 volts-that would be REAL good. My 6 cell 1400mah Sanyo pack just off the charger wiill drop to 6.72 volts when starting a cold engine.
