I was able to modify a cord for the 50L.
I've got an empty dryer port that isn't being used in the garage. I guess the previous owner had an electric dryer, then converted to gas dryer, which we are as well, so it's open. This is good because I don't have to install a new breaker or pull wire.
The issue is that my brewing area is the backyard, which is about 100 feet away from the garage. Since, I live in San Diego, 100% of my brewing is out back and I have no plans to relocate closer to the dryer outlet, so I needed a way to bring the power to my area.
I went down to HomeDepot and picked up a 100ft, 10 gauge heavy-duty extension cord. It's very heavy and it wasn't cheap at approx $130.
I cut off both ends and wired a dryer plug on one end and a female straight blade plug on the other.
Next, I cut off the end of the BM power-cord and wired in a male straight blade plug.
Then I plugged them together, I was concerned that it would come apart easily but they are very snug.
Lastly, I checked everything with a volt meter.
Total cost for this is about $150
