What do you think about my situation Dugster,,,, 2 post above,,,
Your setup is similar to mine, so I would expect that they draw about the same voltage and current levels. You didn't specify whether you are using 2 batteries for the radio, or one of each of the 2700's for radio and ignition.
Assuming you're talking about two radio batteries, I think you can remove one of the 2700 Mah NiMH without any danger. If you don't feel comfortable with only one battery and switch, go with two 1400 or 1600 Mah (6.0v) and a BatShare (see URL below) to ensure redundancy.

If you are using a 2700 Mah for the ignition, change it to a 1400 - 1600 (4.8v) pack and cut that weight in half.[8D]
