Abstract: End caps for a battery pack. The end caps have opposing flanges for securing therebetween batteries. At the lateral edges of the flanges, a space is provided for at least a portion of a battery being secured in the pack to protrude outwardly, so that the battery pack is secured without extra width for the end caps. The end caps are compressively engaged to make electrical connection with the terminals of the uppermost and the lowermost batteries. A strapping tape is utilized for wrapping the battery pack around a longitudinal exist to tightly compress batteries between the end caps. The tape is covered by and further compressed with a tightly compressing shrink wrap material.

Abstract: A solderless battery pack. The pack has a generally thin wall cell body portion with two tubular segments each adapted to hold a plurality of batteries. An upper end cap and a lower end cap are provided for fitting tightly over the upper and lower ends of the cell body portion, respectively. The end caps are compressingly engaged to make electrical connection with the terminals of the uppermost and the lowermost batteries by use of opposing all-thread fasteners, or more preferably, by use of shrink wrap tubing. More preferably, instead of all-thread fasteners, a filament type strapping tape is utilized for wrapping the battery pack around a longitudinal exist to tightly compress batteries in each column of batteries. Then, the tape is covered by and further compressed with a tightly compressing shrink wrap material.

An upper end cap and a lower end cap are provided for fitting tightly over the upper and lower ends of the cell body portion, respectively. The end caps are compressingly engaged to make electrical connection with the terminals of the uppermost and the lowermost batteries by use of opposing all-thread fasteners. The all thread fasteners each extend through the upper and lower end caps and and along side of the cell body portion in a spaced apart relationship. The all thread fasteners are removably affixed by nuts below and above the end caps. In this manner, batteries are provided a complete electrical circuit without current draining soldered or welded contacts.
