To protect lithium batteries from cold while charging, a video/blog showcases using a Chinese diesel heater in an off-grid ham shack. It's vital to keep batteries above freezing, a lesson learned from electric cars in winter. The video details the installation and operation of a 3kw Vevor diesel heater, which also powers up using the ham shack's LiFePO4 batteries, maintaining ideal temperatures for both batteries and equipment.

This video shows charging Power Queen LiFePO4 batteries with a vertical wind generator and discusses off-grid ham shack power storage solutions, including during non-solar conditions.

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.

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.

The author discusses choosing a solar charge controller suitable for radio communication. He focuses on three criteria: portability, radio frequency quietness, and Maximum Power Point Tracking (MPPT) functionality. Recommending Genasun due to its compatibility with these requirements, he mentions his dissatisfaction with another brand, Victron, that caused excessive radio frequency noise. For optimal results, he suggests keeping devices DC powered and using no inverters. He provides specific instructions about matching controllers to battery and solar panel specs, and suggests parallel configuration for Genasun controllers.

The post warns against the use of QRO radio systems for off-grid or grid-down situations due to their high energy consumption. Instead, it advocates QRP radios, suggesting they offer greater efficiency and ease of use with renewable energy sources such as solar. The post also dismisses the idea of lowering the transmission power of QRO radios as a solution, arguing that it does not address issues with energy inefficiency and that such advice is misguided.

Retevis, a renowned radio brand, has introduced budget-friendly and feature-rich dual-band HTs, the Retevis RA89 and the RA79. The RA89 is IP68 waterproof and dustproof, boasts a USB-C charging port with an optional dock, and provides clean clear audio. The RA79 offers wide reception from 50Mhz to 600Mhz and a unique functionality to swap batteries without powering down the radio due to its USB port placement on the radio case. These radios are on sale during the Retevis's Black Friday event ending on 24 November.
