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 is some data I posted last year on a converter (Paramode 4455TC modified to go to 14.8v using its voltage pot) showing the voltage difference vs current as charging progressed: Note the constant current stage.
"-Pair of 6s rated at 232ah , est at 50% SOC capacity. Charging with Honda gen 124v
Time, amps, AH, battery v, converter v
1117-20 starts at 62.3a, drops then recovers as usual when starting off, settles on 61.0 with batt v at 13.1, conv v at 13.41.
1125, 61.1, -, 13.19, 13.52
1150 (30 min mark), 60.7, 32, 13.50, 13.80
1220 (60 min), 60.2, 61, 14.00, 14.32
1227 tapering started amps curved over from 60 to 58 at 67AH (80% SOC)
1240 (80 min) 49.2, 80, 14.34, 14.62
1250 (90 min) 39.8, 86, 14.48, 14.68
1300 (100 min) 32.0, 91, 14.55, 14.72 (at 90% SOC)
Of interest is how the spread between battery and converter voltage is maintained at 0.3 diff while amps are in 60amp range then as amps taper at higher SOC, the spread is down to 0.2v--more or less what you would expect happens"
---I have a plot of a PowerMax showing the voltage diffs when in constant current too if I can find it --will add here if so.
