Primary Lithium Battery System

The primary lithium battery system consists of 10 LM 33550 cells connected in 2 groups of 5 cells in series providing 2 nominal 12 V sections at connector. These sections can be connected in series (for 24 V) in parallel (for 12 V), or used as two separate 12 V units.

KEY FEATURES OF PRIMARY LITHIUM BATTERY SYSTEM:

• A non-replaceable fuse is incorporated in the negative leg of each series group of cells
• A normally closed high temperature switch or thermal fuse is incorporated into each series leg of cells
• Internal series string short circuit protection incorporated into each leg of the battery
• A diode is incorporated into the positive leg of each series group of cells to prevent charging or flow of current into the battery
• A device consisting of a manually activated switch and resistors designed to discharge the battery to 0 V is built into the battery (optional)
• Optional design with push button state of charge indicator is available
