You mentioned you can get 10 channels of data. One example was charging/discharging a battery. Those two items are exclusive of each other. But if I had, for example, air temperature and water temperature and those were in the “333” location (T#sss,111,222,333,444,555...), do I send two packets? One packet for the lower half (000-499) and another packet for the upper half (500-999)? Or does the packet end up being longer as in, T#sss,111,222,333,444,555,666,777,888,999,000?

Apparently I never wrote it into the spec, just asuemd everyone agreed it made sense.
So I did add it to the APRS1.2 page in April of this year.
See spec additions: http://aprs.org/aprs12.html
THe original spec was clearly defined as 5 channels of fixed 3 digit values. It became obvious that 000-999 also fit within the fields and so it made no sense to limit values to 000-255
