For commercial users of DJI Phantom and DJI inspire - these meters can be soldered/XT60 "Inline" via the Power DC cable - some skill to ensure polarity is not reversed - ie by EE's to give accurate power mah readings - keeping track of dji batteries capacity for battery logbooks - call us for info 07 5598 3999
Question - Do you know how much power your Quad pulls in the hover? No ? Ok so this is what we use for that - A WATT meter is used to get definative power flow data in AMPS used for any given flight of a Multicopter (Volts x Amps = WATTS) - Simply place it inline between the Battery and the Battery connector - go out and hover and come back. then fly again and do some peak power climbs - come back and check it again. It will record the peak values. What we really like about this version is it has a built in Cell balancer - so without needing any kind of power in the field you can connect it to a LiPo and wait for it to balance that LiPo and beep - so easy - it will warn of a LiPo imbalance in a pre-flight check too - then do soething about it for you - none of our other Cell meters can do BOTH. It also has an onboard uSEC generator so it will also control an ESC for you - if your doing power tests on a bench rig. It then shuts off. Very useful for finding out power consumption of FPV gear ; Radios ; and just about anything that runs on 7.2v or more - can also be used to compare 4 motors individually etc. When your not doing that - we use it to balance up any LiPos.
We recommend to disconnect it when not being used - although it uses very little power (20ma) in its off state - but will eventually if left connected for days on end damage the lipo

TWO-METER features precise resistors. It has three functions of ‘watt-meter’, ‘battery checker’ and self-balancer. Those functions are essential for electric flyers to ensure safe battery condition and to measure the electric consumptions of the power system. And also, the built-in self-balancer can equalize the individual voltages instantly. TWO-METER can handle all types of Lithium batteries(LiPo, LiIo, LiFe) consisting of serial-wired cells, but the battery pack has to have a balancing plug for checking voltages.
The Watt-meter circuit can measure the electric current up to 100A. You can verify the electric consumptions on your power system. You can drive the ESC without radio and receiver, using integrated signal generator.
TWO-METER can show you the voltage and residual capacity of your Lithium battery pack with its individual voltage of each cells.
TWO-METER has an integrated self-balancing circuit which is self-operative without linking to charger. When you connect the battery pack to the individual port of the device the balancing job will be started instantly. In this case the individual cell voltages will be equalised to the lowest cell voltage of the battery pack.
Servo Drive / Test
TWO-METER has a integrated signal generator to drive the servo. In 'Watt' menu, you can control the servo by increments or decrements of signal. To drive the servo, a battery pack of 4.8V is necessary in connection of Y-harness.
