This tutorial demonstrates how to connect two 12-volt batteries in parallel using Power Queen 12.8V, 100Ah, 1280Wh lithium iron phosphate batteries. The provided YouTube link offers a detailed guide. For related content, explore building a solar-powered Off-Grid Ham Radio Station and information on radio-friendly MPPT charge controllers and off-grid communications.
The Off-Grid Ham Shack series discusses creating a self-sufficient ham radio station or ‘Ham Shack’ capable of operating on solar power during any grid down scenario, emphasizing the importance of an energy strategy for off-grid communications. This system includes solar panels, a charge controller, battery, and power distribution system. Key elements are the use of photovoltaic (PV) panels to harness solar energy, a solar charge controller to regulate energy flow and prevent battery overcharging or damage, and a battery to store energy for later. As well, power distribution ensures the allocation of power to multiple devices simultaneously. A grid-down energy strategy is crucial to any communication-related emergency, be it CB, FRS, GMRS, MURS or PMR radio, UHF CB, DMR, DStar, Meshtastic or LoRa communications.
The blog post highlights the benefits of Power Queen LiFePO4 batteries for off-grid projects over traditional lead-acid batteries, focusing on the better performance and cost-effectiveness in the long run. Additionally, it provides subscribers with information and discounts on Power Queen’s Christmas offers, and illustrates how LiFePO4 batteries function in an off-grid system. It also includes descriptions and respective links of the batteries suited for specific needs in the US, Europe, and Canada.

In May 2023, Julian OH8STN, Ed WQ2U, and Oliver DL4KA set off on an off-grid communications field test above the Arctic Circle. The team aims to test new strategies for off-grid communications, spanning portable power, robust hardware, and antenna efficiency. The expedition will take place near Rovaniemi, Finland. Also, part of the testing includes new robust packet radio capabilities and power supplies. The team encourages interaction from the community via Winlink and APRS messages.
