Use this 4x AA battery tester to safely 'test' your electric blaster with Alkaline or NiMH batteries.  Safety first.  When you have freshly wired you blaster NEVER TEST IT WITH A LIPO PACK OR ANY OTHER HIGH DISCHARGE BATTERY.  Doing so can potentially burn out electrical components in your blaster if you have got your wiring wrong, short out your battery and have dangerous consequences.  Always test with some Alkaline or NiMH batteries for testing purposes as this chemistry is much safer to use for this testing purposes.  

This 4x AA battery tester comes complete with XT60 female connector soldered on.  Simply insert your Alkaline or NiMH batteries and get testing!

Complete your wiring, visually check to your circuit diagram checking all connections and runs are sound, also make sure flywheels spin freely and are not rubbing etc, when you are happy, plug in your AA battery tested with Alkaline or NiMH batteries, test the blaster making sure everything is running, if not unplug the battery tester and fault find, make necessary corrections to your wiring/blaster, re-plug the tester in, make sure everything is running correctly, if so great and unplug the battery tester.
