First Claim
1. A battery pack for powering a cap lamp comprising:
- a. a battery pack housing;
b. a battery cell having a lithium-based chemistry positioned within said battery pack housing and having a pair of terminals;
c. an electronic control module positioned within said batter pack housing;
d. a protection circuit electrically attached between the pair of terminals of said battery cell and the electronic control module and positioned within the battery pack housing;
e. a pair of battery pack posts in electrical communication with the electronic control module and adapted to be electrically connected to the cap lamp;
f. said electronic control module controlling discharging of the battery cell when powering the cap lamp and charging of the battery cell when the battery pack is connected to a charger.

Abstract
A battery pack features a shock-absorbing and sealed construction and an electronic control module that provides automatic recovery circuitry in the event of a short circuit in the load whereby the power is terminated and then restarted at a lower level so that removal of the short circuit may be detected. Full power is restored to the load when the short circuit is removed. In addition, the electronic control module of the battery pack uses the battery pack load, such as a cap lamp, to provide an indication of a low battery charge level. The electronic control module also provides a soft-start feature where the power provided to the bulb is ramped up to avoid current in-rush to the bulb during startup.
