Power Box for Bioenno Battery
15 December 2021 | by 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:
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.
Powerwerx PWRbox
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.
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.
