This is a simplified multiple 3Ah battery set to be used separately or in parallel using a Powerpole distribution block<\/a><\/strong>.<\/p>\n\n\n\n

This build came from a discussion with Steve KM9G, pondering the incorporation of batteries into the lid of a Pelican-like case. My intended case for this is the Nanuk 910<\/strong><\/a> case. This battery model itself is labeled “QRP” because of its individual capacity, but in tandem the batteries together in a case can power a QRO (i.e. 100w) rig like an FT-891.<\/p>\n\n\n\n

Total battery case capacity: 8.55Ah (rated).<\/p>\n\n\n\n

The Powerpole block is 3D printed with 45A connectors. It contains 5 Powerpole ports, 3 on top, one recessed on one side, and one protruding from the other side. This allows for combined output to a rig, while leaving another port open for another 12V device or input from a charger or solar controller (e.g. a Buddipole Power Mini). <\/p>\n\n\n\n

This is designed to be a ham radio case with built-in power for a rig like a Xiegu G90, a Yaesu FT-857, Yaesu FT-991, or similar brick form factor radio of less than 2 to 3 inches high. The main point being: The lid of a case is rarely used, so why not fill it with batteries for your gear?<\/p>\n\n\n\n
