Review on ⚡️ RGBZONE 150 Amps Power Analyzer: High Precision RC Watt Meter for RC, Battery, Solar, Wind Power by Daniel Ortiz

I bought about five of these. They are suitable for low voltage, but if you reach the rated voltage of 60V, wait with a fire extinguisher. Two of them went out in a blaze of glorious flames and putrid semiconductor smoke. And while I've never exceeded the suggested limit of 150A, I would never run more than 40A through the wires of these devices, and even that seems high. They work well down to 50V and I like the auxiliary input so the meter will work even if there is no voltage on either side. If you want to use higher voltages/currents, get a shunt controlled device. You are much safer. To update. Except for two. two more some dust.
