The TURNIGY watt meter is a very accurate R/C amp/watt meter.
Predict model airplane flight time with any given propeller. Ensure peak currents are safe for motor, ESC, wiring and connectors Check battery health and performance. Evaluate R/C battery charging efficiency. Choose the best propeller or gearing and the most efficient motor Check for wiring and connector power losses Measure power and energy consumption of ANY device with a battery
Operating voltage: 4.8~60V (0V with optional auxiliary battery)
Umm... okay, Anyway I'm dumb enough to try. It may act like a resistor where if you use two of the same resistors, the current will be equally divided between them and the total resistance will be cut in half. I should be able to take the reading from one of the two and double it or something to get the total current, at least I hope it works that way.
Hey wellmanite! Very interesting experiment. Theoretically it should work, since the current would split in to two ways through two meters. Still not that I want to use it that way, but I'm just curious. Let us know if it does work! :)
Knowing HK's shipping speed, it could be a couple months till I finally try it and reply here. I'm going to try it with a little 30A meter first to see if wiring a bypass or weak resistor affects anything.
It is looking good, I tried it with the tire warmer pulling 4A through this meter, then I connected the tiny 30A meter in parallel and it stole 3.3A, so the 130A meter read .7A. So, if two meters of the same resistance are used the current should divide perfectly in two. I was using several jumper leads of various lengths and gauges, so there was nowhere near equal resistance anywhere in my experiment.
Accurate, measures 12.02v versus 12.04v from my Fluke 73 III meter. The only issue I have is that the display is very difficult to read. In the dark it is near impossible to see. With bright indoor light it can be read at an angle. To see the data clearly requires putting a flashlight directly on it. It has nowhere near the contrast as shown in the pictures.

Great meter, had some problems at first, but it all worked out. Turnigy is a great company!
