The reason we don't keep SOC at 100% with voltage and current below ending amps is because it is calculated based on amp-hours into and out of the battery and remaining amp-hours. The only reason it resets to 100% SOC after an Absorb cycle is that this is really the only time it makes sense to be done. Good thing there is at least one time that this can be done. Of course, it has to be assumed that going from Absorb to Float transitions at the right amount of Absorb time and MAYBE ending amps but we have discussed even better ways of doing this somewhere on this forum a while back. Maybe some day.

As for higher resolution, internally the resolution is either 32 bits or even 64 bits because Amp-Hours must be accumulated as amp-seconds or even smaller ticks to get it right. I guess it could be made 0.1% resolution but it would take time that I don't have right now.

However, as soon as you can get those modbus specs you want, then you could I suppose calculate all of that yourself externally if you really wanted it. The WB Jr. only reports back to the Classic ~around~ 10 times per second so it's not ALL that fast that modbus couldn't read each reading I think.

OK, back on my head for now but I had to pop up and say hi at least. I'll look at a couple more items and see if I can appear useful.

Happy summer ! I'm tired of being cold and wet up here !
