[NSRCA-discussion] regulators

[J.Oddino]

No.  As long as his battery is .2 volts above the regulated voltage (5.7) he is okay.  This means it would regulate down to a battery voltage of 5.9.  If the input falls below 5.9, say to 5.5 the output will be about .2 volts less or 5.3.  That is why the system will not quit if you lost one cell in your two cell LiPoly pack.

  Understand what you say but does he have a problem with his lower than regulated volts.

    Bob,
    You're right, the voltage out should stay constant.

    Jim,
    The 480 is more than capable of maintaining 6.11 volts under a 1500 mah load - and this is shown by Bob's test where the 480 holds 7.2 volts under direct load.  The 480 will actually maintain 6.11 volts with substantially higher load (upwards of 5000 mah).

    Regards,

    Dave Lockhart
