See the charge level of a large-cell battery while protecting it from power surges. This monitor also checks the condition of your charging system.

Connect these shunts to a battery and a panel meter or electrical testing device to measure the current flowing through a circuit when the current is too high to be measured directly by a meter.

Test large engine batteries that draw up to 500 amps. Turn the dial to vary the load applied to the battery to see how it performs at different loads.

Measure the voltage of your batteries as well as the current they can supply to check battery health.

See how much electricity motors, generators, and other electrical equipment use. The high-visibility digital screen displays electrical measurements with more accuracy than an analog panel monitor.
