Description

An RV or marine battery monitor should at least tell you the Amp hours drawn from your battery and the Amps being drawn. Our "Doc Wattson" battery monitor does that and much more.

The Amp hour (Ah) and Kilo Watt hour (KWh) measurements are much more accurate "fuel gages" than voltage measurements which depend on many other factors. Kilo Watt Hours are better than Amp hours because the effects of voltage change are included in calculating the actual energy delivered to the load. Ah and KWh are much more accurate than the voltage based RV or marine "Battery Indicator" measurements.

Peak Amps and minimum volts measurements show you even short duration load events and help you troubleshoot hard to find electrical problems. Statistics are reset when power is removed.

Doc Wattson helps you evaluate the effect of component changes and of system tuning on performance.

Product Comparison

Doc Wattson Meter
Parameter Range Resolution Accuracy
(worst-case)
Voltage 0-60 Volts * 0.01 V ± (1% + 0.035)
Current 0-100 Amps *** 0.01 A ± (2% + 0.06)
Power 0-6554 Watts 0.1 W  
Charge 0-6554 Amp hours 0.1 Ah  
Energy 0-650 Kilo Watthours 0.01 KWh (10 Wh)  

Increased measurement range compared to Watt's Up Meter shown in bold type.

But only measures seven DC values with less resolution:

  • Amp-Hours: (0 - 6554)
  • Kilo Watt-hours: (0 - 650)
  • Amps: (0-100 peak)
  • Watts: (0 - 6554)
  • Peak Amps & minimum Voltage ("sags")

Works with 12, 24, 36 or 48 volt batteries up to 60 V. Lead acid, SLA, Gel Cell, and other battery types are all compatible.

* Using auxiliary power/battery input. Minimum is ~4.0 V without it.
*** 50 Amps continuous. Derate for wire temperatures above 70 Deg C.

Watt's Up Meter
Parameter Range Resolution Accuracy
(worst-case)
Voltage 0-60 Volts * 0.01 V ± (1% + 0.035)
Current 0-100 Amps *** 0.01 A ± (2% + 0.06)
Power 0-6554 Watts 0.1 W  
Charge 0-65 Amp hours** 0.001 Ah  
Energy 0-6554 Watthours** 0.1 Wh  

Measures up to eight DC values with much higher precision.

  • Amp-Hours: (0 - 65)
  • Watt-hours: (0 - 6554)
  • Amps: (0-100 peak)
  • Watts: (0 - 6554)
  • Peak Amps & peak Watts
  • Minimum voltage ("sags")
  • Voltage: (0 - 60)

Works with 12, 24, 36 or 48 volt batteries up to 60 V. Lead acid, SLA, Gel Cell, and other battery types are all compatible.

* Using auxiliary power/battery input. Minimum is ~4.0 V without it.
** Much higher at reduced resolution.
*** 50 Amps continuous, 3-wire connection. Derate for wire temperatures next to case above 70 Deg C.

Best DC Power Tool Ever Without Breaking The Bank!
By from Portland, Oregon

This tool is so handy for working on DC powered equipment. I used it for confirming the DC power requirements for remote radio alarm units that I designed and built. It is especially nice for calculating power requirements. After estimatiing using the manufacture's specifications, the Doc Wattson Meter gives you real world DC power information. It is great for sizing power supplies, solar panel arrays and battery backup systems. Every DC electrical mechanic should have on their bench and in their tool bag. The fact that they are pre-connectorized with Anderson Power Pole connectors is a great bonus.

A great meter
By from Riverside CA

This little meter is a great addition to anyone's tool box. Depending on which direction you connect it you can either read the charge running into or out of your battery or source. I used the Doc Wattson Meter to measure loads drawn by my amateur radio and portable freezer allowing me to correctly size the cables and battery. Connected between a recharger and the battery it lets me measure the charge state of the battery.
