5 . The battery system of claim 4 , wherein the digital information is at least one of a value, a password, a command, and a signal.

6 . The battery system of claim 5 , wherein the digital information is encrypted and the processing circuit of the battery and the processing circuit of the receptacle contain a key to encrypt and decrypt the digital information.

7 . The battery system of claim 6 , wherein the battery is further configured to transition between a locked mode and an unlocked mode, wherein the locked mode comprises preventing the battery from outputting power above a power threshold and the unlocked mode comprises allowing the battery to output power above the power threshold.

8 . The battery system of claim 7 , wherein the battery is configured to transfer from the locked mode to the unlocked mode based on the transfer of information between the processing circuit of the battery and the verification circuit.

9 . The battery system of claim 6 , wherein the battery is configured to default back to a locked mode when the battery is removed from the receptacle.

10 . The battery system of claim 1 , wherein the battery is further configured to transition between a locked mode and an unlocked mode, wherein the locked mode comprises preventing the battery from outputting power above a power threshold and the unlocked mode comprises allowing the battery to output power above the power threshold.

11 . The battery system of claim 10 , wherein the battery is configured to transfer from the locked mode to the unlocked mode based on the transfer of information between the processing circuit of the battery and the verification circuit.

12 . A receptacle assembly for power equipment, the receptacle assembly comprising:

a receptacle housing;

a plurality of terminals configured to connect to a plurality of terminals of a battery; and

a receptacle processing circuit configured to communicate with a processing circuit of the battery; and

a verification circuit configured to communicate with the processing circuit of the battery and enable the battery to transition into an unlocked mode where the battery is allowed to output power above a power threshold, wherein the verification circuit is within the receptacle housing, and wherein the receptacle housing is integrally formed with a housing of the power equipment.

13 . The receptacle assembly of claim 12 , wherein the receptacle processing circuit is further configured to continuously communicate with the processing circuit of the battery during a transfer of power from the battery to the plurality of terminals and the continuous communication between the receptacle processing circuit and the processing circuit of the battery is necessary for the continued transfer of power from the battery to the plurality of terminals.

14 . The receptacle assembly of claim 12 , wherein the receptacle processing circuit is configured to communicate digitally with the processing circuit of the battery and the information sent by the receptacle processing circuit is digital information.

15 . The receptacle assembly of claim 14 , wherein the digital information is at least one of:

a password;

a value;

a number;

a command; and

a request.

16 . The receptacle assembly of claim 15 , wherein the receptacle processing circuit is configured to encrypt the digital information and send the digital information to the processing circuit of the battery.

17 . A method for connecting a battery to a receptacle, the method comprising:

removably connecting the battery to the receptacle, wherein the battery and the receptacle are electrically and communicably connected;

transferring information between a processing circuit of the battery and a processing circuit of the receptacle; and

the processing circuit of the battery communicating with a verification circuit within the receptacle to enable the battery to output power and transferring power from the battery to the receptacle based on the transfer of information between the processing circuit of the battery and the verification circuit.

18 . The method of claim 17 , further comprising transferring power from the receptacle supplied by the battery to a motor of a power equipment.

19 . The method of claim 18 , further comprising:

sending digital information regarding a presence of the battery from the processing circuit of the battery to the processing circuit of the receptacle;

receiving and processing the digital information regarding the presence of the battery from the processing circuit of the battery with the processing circuit of the receptacle;

sending digital information from the processing circuit of the receptacle to the processing circuit of the battery to allow the battery to supply the receptacle with power; and

processing the digital information sent from the processing circuit of the receptacle with the processing circuit of the battery and transferring power from the battery to the receptacle.

20 . The method of claim 19 , further comprising continuously transferring information between the processing circuit of the receptacle and the processing circuit of the battery to maintain the power transfer from the battery to the receptacle.
