Any aircraft that utilizes a supported electrical system or an electric starter needs a battery. The unique open-air nature of the Quicksilver line of ultralights does not provide many hiding places for items like batteries and electrical support items. Air-Tech, Inc. produces a clean and compact battery box to support all the electrical requirements for the Quicksilver builder. The standerd assembly that attaches to the Root Tube of the SportII, Sprint II and the Sport 2-S is complete with all components to provide 12 volt power for your instruments and assessories. A provided Regulator / Rectifier is mounted to the assembly and it provides for the charging system of the battery. Typically a push button starter switch and a Master On / Off toggle switch is included. Also available is the 8 gang fuse holder that provides fused outlets for additional ancilary items like radio, GPS, lighting and intercom systems.
