Watt Meter,

[Grow Pattern]

Did you all know if there is a max voltage limit on electrics??? Is this true and if so where can I find it to read??? Is it just FAI??

Need help finding it.

Eric.

  Or if you want data quick and easy, the AstroFlight Whattmeter provides a direct readouts up to 100 amps, 60volts, 6,000 watts.  Also shows the
  amps put in during charge.  It does not have an internal battery, it needs at least 4 volts from the battery under test/charge.
