Quick reference

The datasheet prints "The Cyrix-ct 12/24 automatically detects system voltage."; the API prints "12V or 24V (automatic detection)". The 120 A manual, which also covers a 24/48 V version, says the Cyrix-ct adjusts to a 12V, 24V or 48V system and that it is used only in installations with a negative common.

The datasheet prints "Cyrix 12/24-120: 13 mm (M6)" under long bolts; the API prints M6 bolts and Faston tab 6.3 mm for the battery minus and start assist terminals.

The manual prints that the Cyrix-ct is a microprocessor controlled heavy duty relay that connects batteries in parallel when one battery has reached a preset voltage and disconnects when the voltage decreases below float level, and that it senses the voltage of both connected batteries. The price list calls it an "intelligent combiner".
