Power Box for Bioenno Battery

When operating portable, I use Lithium Iron Phosphate batteries from Bioenno. Most of my portable operating is for Summits On The Air (SOTA) and I wrote about it here:

My SOTA Battery Journey

For POTA activations, I purchased a larger, 20 Ah Bioenno battery and use it to power a Yaesu FT-991 (and other radios). This battery has worked out really well. It is a bit large for backpack portable and weighs 5.4 pounds, but I have taken it along on a few SOTA activations.

I decided the battery could use a case to protect it while being tossed around in the back of the Jeep. Powerwerx has a really good battery box that includes a digital voltage readout, automotive (“cigarette lighter”) socket, dual PowerPole plugs and high-current binding posts.

Initially, I did not think I needed the extra gizmos, and I did not want to take up more space with the battery system. Later, I figured that I could always pull the battery out of the box and use it in its original form.

The power switch is handy for turning on/off the battery power and the digital voltmeter provides a simple view of the battery condition. Most of the time, I use the PowerPole connectors to connect up my radios but occasionally the automotive socket comes in handy.

The 20 Ah Bioenno battery sits inside the box with plenty of room to spare.

I used some of the plastic packing material that came with the box to hold the battery in place. A little bit of cutting with a sharp knife produced a good fit. There is enough room above the battery for the Bioenno charger, so it makes for a nice kit. The charger connects to the original charging plug on the battery.

As expected, Powerwerx did a good job of wiring up the various components and included fuses in both the positive and negative cables. The box is big enough to hold a 40 Ah battery and I am tempted to upgrade it for larger capacity, but the 20 Ah battery has been sufficient, so far.

I’ve used this battery box for multiple POTA activations and a few other situations when I just needed to power up a radio at home. It works great. The voltmeter gives me a quick check of the battery status and the PowerPole connectors make for easy hookup.

The PWRbox costs $109.99, battery not included.

    I built my own using Powerwerx parts and an ammo box from Harbor Freight. It is smaller and more portable with a 12A Bienno battery. I use it for my 5 watt QRP rigs and it powers things seemingly forever. 73.
