This listing is for 1 piece of battery connection polarity protector for DC source upt to 15V, and load up to 2A with <=0.01V dropout

The device is to be installed  between a battery connector and a powered circuit. It will protect the powered circuit if user accidentaly connects battery in the wrong direction (polarity) by instantly disconnecting the circuit from the battery. 

This polarity protection circuit has a neglible (less than 0.01 volt) dropout accross itself and practically doesn't use any power itself.

Max input voltage  15V
Max current 2 A (with no noticable heat dissipation)
Above parameters are confirmed by practical measurements.

There are two options - with the installed 9V battery clip or without.
