Beware Puffed LiPo Batteries

Back in 2021, I was working with a young ham looking to learn Morse code. As he was blind, many of the tools commonly used, were not as useful. I stumbled upon the Morserino-32, a wonderful device from Willi OE1WKL, I bought a pair of them in kit form, and soon had my young fella sending and receiving Morse.

Recently a somewhat older ham (about 70 years older than my young student) mentioned he was having issues transitioning from CW skills learned on a bug decades ago to modern paddles/keyers. I immediately though of the “Echo Trainer” mode in the Morserino-32, which had been boxed up for the past 5 years. Upon examining one of them, I discovered that the 3.7v LiPo battery had “puffed”. This is a sign of a failed battery.

Since many ham devices use LiPo batteries, I thought I would remind folks to beware [of] puffed batteries. It is quite dangerous to attempt to charge and use them. The photo below shows the puffed battery on the left (leads cut off since it can’t be used) and a “normal” battery on the right. If it looks like a pillow, it is time to dispose of it safely & properly. Both Best Buy and Staples offer battery recycling for free.

Safety Stand-Down: Look Up and Live

Electricity is a killer. About 150 people die each year at work from contact with electricity, according to the Electrical Safety Foundation International. Half of those are from contact with power lines. That data is just workplace deaths, so recreational and public service volunteering aren’t even accounted for.

In a recent article, ARRL New Mexico Section Manager Bill Mader, K8TE, shared safety concerns and processes that can be implemented at ARRL Field Day sites. I’d like to share a simple phrase that may enhance your situational awareness: Look up and live.

“Look up and live” was drilled into me and every other television news employee who worked with electronic news gathering vehicles that had a pneumatic mast or satellite dish. It was the title of [this] industry-standard safety video published by the National Press Photographers Association.

In TV news, where I spent the first two decades of my professional career, there was always a deadline and often a tremendous sense of urgency at the scene of breaking news to get a live shot up first. Before the days of bonded cellular internet streaming, we used radio — microwave and satellite — to take viewers to the scene.

No matter the pressure from news managers, safety was paramount. When we approached a scene, we made sure to park the live truck at least 10 feet away from overhead wires to comply with regulations. My personal minimum was two truck-lengths from any lines, ideally a whole mast-length. If I had a 58-foot mast, I’d try to park at least 58 feet away from the nearest power line.

Identifying overhead lines was ritualistic: As I arrived, I got out of the vehicle, walked 20 feet away, looked up and walked around the entire perimeter of the truck while deliberately searching for overhead lines and obstructions. This additional 45-second process could feel like an eternity when news was unfolding dramatically for me to capture and report — but I couldn’t go live if I was dead.

In pursuit of our amateur radio hobby, we should apply even more diligence. There’s no pressure to get on for a ham radio activation. Take your time, walk around, be diligent. Look up and live.

Portable masts, vertical antennas, wire antennas slung up into a tree — anything you put up can become energized if it contacts an overhead wire. Do not take chances. Even what appears to be a phone or fiber line could be carrying lethal voltages. Do not become the path to ground.

One additional tip that I hope never applies to a radio amateur: Should a vehicle you’re in become energized by a fallen line or a mast erected into power lines, do not leave it unless it is on fire. Call for help via phone or ham radio. Yell at any bystanders to not approach your vehicle. Electricity spreads out from a path to ground in concentric rings of decreasing voltage. Being in contact with different voltages is what will kill you. If a fire requires you to exit, carefully jump clear of the vehicle so as to not contact the vehicle and ground simultaneously. Be mindful of your movements: “Bunny hop” with your feet together or shuffle your feet on the ground in small increments without lifting either of them. Do not provide a path between the different potentials by walking normally or by falling and catching yourself with your hands.

Please be careful when erecting portable gear within the wires environment. Remember: Look up and live.
