sigik: i uise this all the time: http://www.hobbyking.com/hobbyking/store/__40033__Qu anum_Pocket_Vibration_Telemetry_Voltage_Meter_With_A larm.html
it is a low voltage alarm from hobby king too. it vibrates when reaches the voltage you program, and is easy to do so. and weighs only 5 grams. plugs in the charge connector.
Hi, if You are using it with 9XR radio than You can set the alarm down to 4V (but remember that the lower You go with volts the shorter the radio range and the higher risk of killing 3S LiPo battery. Both may leed to a crash) but I dont think it can turn the radio off. 9XR informs on the main screen what is the actual Lipo voltage in the radio (not in the plane unless You have a telemetry). It's always better to check radio voltage before going out to the field.
how do you guys charge it? i do it through the 4 pins connector, as i do the same with all the other packs, and don't have an adaptor for the red connector, but takes hours to do so.
your experience will be appreciated.
You can use a small charger that only uses the balance plug (as you are doing). It is usually slow. You could use a bigger charger, such as the "Turnigy Accucell-6 50W 6A Balancer/Charger". With that one you can charge the battery at 2.2A which will be faster. You will need an adapter for the red plug.
Change NiMH On LiPo 2200mAh and has forgotten about problem of the charging on field...

I have tried out the 9xr battery, and I am pleased with how it works. I put it in my 9xr, and ran it on the simulator. It is holding up very well (all I am running is the TX on it), and I expect no problems.
I am setting up my 12V dremel tool to run on it too (and any 3s LiPo), but I see this one as a good option for it's over and under protection. If my dremel runs it out, it will cut off, so this should work nicely.
