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.

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.
