As a radio amateur who spends a lot of time in the field – especially during activities like Parks on the Air (POTA) and portable microwave radio – a reliable power supply is crucial for the effectiveness and enjoyment of my endeavors. Whether I'm hiking in a national park or setting up a microwave contact on a remote mountaintop, a dependable, portable, and long-lasting power source is absolutely essential.

The harsh truth: My struggles with traditional SLA batteries for amateur radio
For years I used traditional sealed lead-acid (SLA) batteries to power my amateur radio equipment. While SLA batteries did the job, they presented a number of challenges for portable use.
- Weight and bulk: They are extremely heavy and unwieldy – quite frankly, they're simply not designed for mobility. Lugging two SLA batteries, along with a radio, tripods, antennas, and a laptop, into the field quickly became one of the most unpleasant aspects of my hobby. The weight of the battery alone often determined how far I was willing to travel for POTA (Parks on the Air) or how much other equipment I could carry.
- Storage and reliability: Another problem with SLA batteries was storage and their unreliability. During the cold, radio-inactive winter months, I usually store my outdoor equipment. SLA batteries age very poorly in storage – when I took them out again after a few months, they were often severely degraded or completely dead. Even if they were fully charged before storage, they seemed to lose capacity faster than expected. This unreliability led to stress and frustration – when this part of the hobby should actually be fun and relaxing.
The discovery of LiTime LiFePO₄ batteries for amateur radio
It was precisely at this time that I discovered LiTime's lithium iron phosphate (LiFePO₄) batteries. I had already seen some reviews online and heard other radio amateurs talking about them, but was initially skeptical – could a lighter battery really perform better? The answer is a resounding yes.
- Immediate weight advantage: The weight difference was immediately noticeable. I could carry twice the usable capacity at only half the weight compared to my old SLA batteries. This means more gear for POTA activations without overloading myself.
- Strong performance under load: Besides its improved portability, what impresses me most about the LiTime LiFePO₄ battery is its stable performance under load. I operate several radios – from high-powered HF transceivers for POTA to portable UHF and microwave setups, as well as digital modes with my laptop. A stable power supply is essential, especially at high transmit power – and this is precisely where the LiTime batteries excel. Even under load, they maintain a constant voltage – something SLA batteries often struggle with.
- Reliable shelf life: Another advantage is its excellent storage capacity. After the summer season, I simply store my LiTime battery in the garage or radio shed. In the spring, when things get going again, it still has almost a full charge. A quick top-up with a compatible charger is all it takes – and it's ready to go. I never experienced this kind of reliability with my old SLA batteries.
LiTime LiFePO₄: Power supply for all aspects of my portable amateur radio station
My current field equipment can be quite power-hungry. I often carry a shortwave radio with up to 100 watts output power, VHF/UHF equipment, a laptop for digital modes like FT8, a GPS device, and other accessories. Thanks to the high current output and large capacity of my LiTime LiFePO₄ battery, I no longer have to worry about rationing power or operating at reduced transmit power just to conserve battery life.
When I set up for POTA or microwave operation in a remote location, it usually takes me 30 to 45 minutes to set up antennas, position tripods, tune equipment, and prepare my operating area. Knowing I have a stable power source that will run my equipment for hours—sometimes even the whole day—allows me to focus entirely on operating, logging QSOs, and enjoying the surroundings, rather than constantly checking voltage levels or swapping equipment to conserve power.
LiTime has now become the central power source of my portable amateur radio station.
Peace of mind thanks to safety and versatility with LiTime
What impresses me most is the versatility and user-friendliness of the LiTime lithium batteries. The integrated battery management system (BMS) reliably protects against overcharging, deep discharging, and even high temperatures – this gives me peace of mind, especially when operating in the summer heat. I can concentrate fully on flying without having to worry about battery damage or complicated charging cycles.
The conclusion: LiTime LiFePO₄ is a must-have for serious portable radio amateurs.
In short: Switching to LiTime LiFePO₄ batteries has fundamentally changed my approach to portable amateur radio. I'm no longer bound by the limitations of lead-acid (SLA) batteries, I can operate at full power, and I now look forward to outdoor activations even more. The equipment I take with me is now determined by my radio objectives – no longer by how much weight I can carry or how long the battery will last.
If you're a radio amateur who takes outdoor operation seriously—whether for POTA, SOTA (Summits on the Air), emergency communications, or simply for fun on Field Day—then I can highly recommend LiTime's LiFePO₄ batteries. They've become an indispensable part of my equipment and have made every activation easier, more reliable, and more enjoyable.
