[NSRCA-discussion] regulators

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
