Holy crap, I think that I just figured out batteries and charging.
I was putting together some spreadsheets to figure out how many batteries/chargers/generators we would need for the September CMP race and the numbers were getting ridiculous. It's hard to scope because part of the time the chargers are using 100% of the generator and part of the time they are using 5% of the generator.
So I calculated only charging the batteries using the CA part of the charge cycle, which uses 100% of the generator power. That takes about an hour and gets the batteries to 80% charged.
80% charge would let us turn 10 laps per battery set instead of 12 laps, so the spreadsheet for what we currently have looks like this:
That's over 50 laps more that we would do if we charged them to 100%. If we can do 200 laps at CMP in a few weeks, then the world will probably end right there.
Now add just one set of chargers and:
That's 300+ laps and no breaks to charge batteries, just a quick stop every 25 minutes to swap out the battery pack, which took me less than 5 minutes to do by myself the first time that I tried it. With three guys working the swap, I bet we can get it to half that.
That requires one more set of chargers and two cheap Sam's Club generators. That is pretty feasible without killing ourselves or blowing the budget.
I'm getting a really good feeling about this.
Everybody grab your brooms, it's shenanigans!
