PD or Iota for my upgrade?
I'm thinking about a converter and battery upgrade. The batteries will be wet cell lead acid 6 volt Possible T-105s or the 230AH, EGC2 from Sam's club. I'll probably go for four. (Does nayone have...

Here's the best I can do on the switching frequencies. This page Progressive Dynamics FAQ has a graphic that says the switching frequency is 35 kHz (item #4). The text above the graphic says 3.5 kHz. I'm assuming it's the 35 kHz that's correct but the discrepancy doesn't help instill confidence in the info. I vaguely remember measuring my 9160 a long time ago at 50 kHz. So if the 35 kHz and my memory are correct, there are two different frequencies. Lots of "ifs" there.
If you've been following PD converters over the years you probably noticed that multiple versions of the charging algorithm have been published by PD. I attribute this to the marketing people trying to do technical work. The confusion created by the multiple versions drove me to the patents, where one finds that all of the touted
state of charge measurement is nonsense and the converter output voltage is based on stupid voltage measurements and fixed timers. It gets the job done ok, it just irks me when they wordsmith the info to make something sound like something more than it is.
