Why did GEARS choose 12 Volt VRLA batteries for use in the GEARS Invention and Design System kit?
The choice to use a 12 volt system was predicated on the fact that many engineering components using DC current require either 12, or 24 volt power. Readily available items like communications equipment, chip cameras, video transmitters, electrical actuators and sensors operate on either 12 or 24 volts DC. The manufacturers of the GEARS Invention and Design System chose VRLA batteries because they are easily and inexpensively scaled to nearly any engineering power demand. Unlike more expensive battery chemistries that need to be carefully managed, VRLA batteries are easy to maintain and can be recharged immediately after each use without suffering from “Memory” effects. 12 and 24 volt VLRA battery packs are available in virtually any Ahr rating. VRLA batteries are the most economical choice with respect to cost per Ahr and it is easy to create dual 12-24 volt “On-board” power supplies using 2 identical 12 volt VRLA batteries.
