- If two batteries are inserted and one is determined to be already full then the Green light flashes. However once the other battery is full and both are Green the Green light still flashes for the first. I think they should both go solid.
- It would be nice if the very first line printed to the SD card and on serial out was a line that named each column and what info they contain like Voltage or Current.
It would be a bit tricky to do the first one, although it should be doable in theory at least. Personally, I think it makes sense to leave it flashing so that it's obvious that the cell wasn't charged at all since it was inserted. There has to be a window where a cell will be rejected as fully charged even though it's only mostly charged, so it might be at only 95% whilst the other is at 100%, so I think it's useful for the user to be aware that one cell wasn't actually charged. It probably doesn't matter too much in the end since the flashing green happens straight away, I think most users would just take the battery back out straight away rather than leaving it in there while the other charged.
It would be interesting to see what others think about this though?
I did have a header line being added to the start of the log, but I disabled it in the quest to save some space for other program enhancements. I might just re-enable it though...
- Mark, I know you already are aware of this, but I thought I would put it here for reference. If two batteries are inserted then after pressing the button there is still sometimes that not both are detected.
Darn - I thought that it was fixed with the latest version that I sent to you!
I was checking a few times for it last night but didn't see it happen. What percentage of the time do you see it?
- Feel free to delete this if it is all wrong, but i think I may have had a few batteries terminate early because of a bump right when it begins charging. If you don't already I think we should have a min voltage threshold that the battery must be above before we consider it charged. The other thought is that this bump only seems to happen with the combination of new batteries or highly abused batteries and at high charge current. So the other option would be if we could guess if this might happen based on the impedance check and then easy into the full charge current over a period of maybe 5-10min or something to help avoid this bump.
The battery does need to hit 1.44V resting before my inflection termination method will kick in, so that's generally already pretty full. Can you send me the log file from where you're seeing this problem?
