Abstract

An aircraft system battery pack is housed in a housing having a removable cover with a window formed therein. A pair of batteries is positioned in the housing. A lamp is mounted in the window of the cover. A pushbutton switch is mounted in the cover and manually depressible from outside the cover. Electrical conductors electrically connect the batteries in series and provide a DC output voltage and electrical conductors electrically connect the batteries in circuit with the lamp and the switch in a manner whereby manual depression of the switch closes the circuit with the batteries and the lamp. The lamp then indicates the power output condition of the batteries.

Claims

1. A battery pack, comprising

a housing;

at least a pair of batteries in said housing;

a lamp in said housing;

an output terminal;

a switch in said housing; and

electrical conductors electrically connecting said batteries in series and to provide a DC output voltage and electrical conductors electrically connecting said batteries in circuit, with said lamp and said switch in a manner whereby manual operation of said switch closes said circuit with said batteries and said lamp and said lamp indicates the power output condition of said batteries.

2. A battery pack as claimed in claim 1, wherein said housing has a window formed therein and said lamp is mounted in said window.

3. A battery pack as claimed in claim 1, wherein said housing has a removable cover with a window formed therein and said lamp is mounted in said window.

4. A battery pack as claimed in claim 1, wherein said housing comprises plastic material and said switch is manually depressible to close said circuit.

5. A battery pack as claimed in claim 1, wherein said housing has a removable cover with a window formed therein, said lamp is mounted in said cover in said window and said switch is mounted in said cover and is manually depressible from outside said cover to close said circuit.

6. An aircraft system battery pack, comprising

a housing having a removable cover with a window formed therein;

a pair of batteries in said housing;

a lamp mounted in said window of said cover;

an output terminal;

a pushbutton switch mounted in said cover and manually depressible from outside said cover; and

electrical conductors electrically connecting said batteries in one of series and parallel to provide a DC output voltage and electrical conductors electrically connecting said batteries in circuit with said lamp and said switch in a manner whereby manual depression of said switch closes said circuit with said batteries and said lamp and said lamp indicates the power output condition of said batteries.

7. An aircraft system battery pack as claimed in claim 6, wherein said housing and said cover comprise plastic material.

8. An aircraft system battery pack as claimed in claim 6, wherein said batteries comprise high performance batteries.

9. An aircraft system battery pack as claimed in claim 6, wherein said batteries comprise lithium batteries.

10. An aircraft system battery pack as claimed in claim 6, wherein said batteries comprise lithium 24 volt DC batteries.

11. An electro-ballistic system battery pack, comprising

a housing having a removable cover with a window formed therein;

a pair of batteries in said housing;

a lamp mounted in said window of said cover;

an output terminal;

a pushbutton switch mounted in said cover and manually depressible from outside said cover; and

circuit means electrically connecting said batteries in one of series and parallel to an output terminal and electrically connecting said batteries in series with said lamp and said switch, whereby a DC output voltage is provided at said output terminal and depression of said switch closes said circuit with said batteries and said lamp and said lamp indicates by its brightness the power output condition of said batteries.

12. An electro-ballistic system battery pack as claimed in claim 11, wherein said housing and said cover comprise plastic material.

13. An electro-ballistic system battery pack as claimed in claim 11, wherein said batteries comprise lithium 24 volt DC batteries.
