J Perkins Safety Master On-Brd Svo Pwr Analyr
SafetyMaster on board power analyser
This fantastic unit is designed to help you monitor power to your onboard R/C system. Batteries and BEC circuits are two of the critical areas inside your model and when things go wrong these two are often found to be implicated. Thanks to SafetyMaster you can see how safe your system actually is by measuring the current draw of your servos/receiver and by monitoring the performance of your battery or BEC under load.
The SafetyMaster draws a graph of current over time elapsed since turned on and shows total time elapsed plus battery capacity used.
The graph is erased when the power source is disconnected. You can also manually reset the screen by entering “Yes” into the “Rst graph” parameter in the Warning Settings screen.
Warning Settings Screen
In this screen you can adjust warning thresholds according to your needs. Check out the specification of your receiver - or of your ESC if a BEC is used a power source, and your battery, and set warnings
Using a dedicated battery
Choosing a dedicated battery for powering your R/C system is often a better and safer choice instead of a BEC, but please bear in mind the following: a good battery maintains output voltage when a load is applied - or at least doesn’t fall below the nominal voltage. Note that with NiXX batteries - as the battery ages, so the voltage drops. Therefore, if you measure a large voltage drop during testing, it means that the load is too great or the battery is old or perhaps some component in the system has failed. Regarding the current limit; you should set max. current to around 95-100% of that specified by the manufacturer. If the load applied is below spec. and a steep voltage drop occurs it is better to change the battery as failure to do so could lead to a potentially catastrophic battery failure.

Multiplex Watt Meter MX8120
This measuring device is the ideal “assistant“ for any electric flight enthusiast, helping to optimise the combination of propeller, motor and battery. The MX 8120 also provides valuable information for battery maintenance. The screen constantly displays the actual values for voltage [V], current [A] and power [W]. The unit also calculates and displays the charge quantity [mAh] “moved“ (i.e. charged-in or discharged). A separate battery is not required, as the MX 8120 draws the energy it needs to operate from the energy source connected to it.
Typical applications for the MX 8120 are as follows:For testing electric power systems: Measuring the actual values, of current, voltage and power, and the quantity of charge drawn from the flight or drive battery (connect the unit between the battery and the speed controller), For charging batteries: recording and displaying the quantity of charge and the actual values for current, voltage and power (charge power) (connect the unit between the battery and the charger).

ProPeak Pro-Peak Batt. Monitor Li-Po/Li-Fe
Quick to use and small to store, this simple LED display unit can measure the individual and single cell voltage of any Lithium technology pack up to 6S. The unit cycles across the individual voltages and then the total voltage in turn.
The small size and low weight means that you can mount it in the model or use as a hand held unit.
The unit pins are spaced at 2.5mm for XH plugs and an adaptor lead is included for 2.0mm spaced pins like EH and TP.

Item Name: ProPeak Pro-Peak Batt. Monitor Li-Po/Li-Fe
ProPeak Pro-Peak Watt Meter
At last, a heavy duty watt meter that can monitor the power consumption of your motor/load source and `freeze' record the peaks for later checking. The Watt Meter can be used to measure battery performance, motor performance, charger performance, speed controller (ESC) performance or even the current demanded by a receiver/servo combination. An important feature to decide if a BEC has enough power. The moulded plastic case has an easy-grip finish and the unit is both compact and durable. The blue illuminated, LCD display is clear and logically laid out for easy understanding.
• Operates From 4.8 ~ 60V From 0V With Optional Auxiliary Battery
• Current (Amps) 0~130A, Resolution 0.01A
• Voltage (Volts) 0~60V, Resolution 0.01V
• Power (Watts) 0~6554W, Resolution 0.1W
• Current Delivery (Amp Hours) 0~65Ah, Resolution 0.001Ah
• Energy (Watt Hours) 0~6554Wh, Resolution 0.1Wh

Futaba Batt Checker/Balancer Univ
Click here to see a slideshow.
The new Futaba BR-3000 Battery Checker is a sophisticated unit that can be used to check a wide range of battery packs of varying voltages, with Li-Po, Li-Fe and Li-Ion packs of 2-7 cells, and Ni-MH and Ni-Cd packs of 4-7 cells all being suitable for checking with the BR-3000. Important information such as total pack voltage and remaining capacity are available for all packs, whilst those using Lithium technology can also be checked for individual cell voltage, minimum and maximum cell voltage and cell voltage differences, as well as being able to take advantage of the included balance function.
