Bandido II battery check mod

[Carl-NC]

Here is the mod I did on my battery check, according to my notes. The original circuit applies a voltage to R13 equal to 2*Vbatt - 10v, so the audio will progessively weaken until Vbatt=5v. However, a fresh battery will damn near blow your eardrums.

My mod is to transpose the R8-R9 values, and drop in a 68k to ground. Now 1/3rd of Vbatt is compared to 2v, thus you get a green light until Vbatt=6v. I might have omitted R11 altogether, it should not be necessary, unless for stability purposes.
