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 Safety Master 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 Safety Master 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 systemis often a better and safer choice instead of a BEC, but please bear in mind the following: agood battery maintains output voltage when a load is applied – or at least doesnt 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 theload 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.
