Well, I'm back from vacation, and ready to finish this thing up! Today I took the time to reprogram the arduino for use with the celllogs. Using the celllogs really simplified the code. Basically, it waits for an alarm. When the alarm goes off, it will send a signal to disconnect the 110V power to the charger.
I originally had it setup so it would reconnect the power after 1 hour. But, since I believe that balancing at the bottom is probably a superior solution, I have taken this out of the program. Once the celllog alarms out, the charging will stop. If you want to keep charging, you'll have to unplug the cord, and plug it back in. This resets the arduino and start things over again. So, as soon as the alarm goes off it'll stop again.
I'm still working out how I want to do the 12V disconnect to the dc to dc converter. I'd like to keep this as simple as possible, and I still have the problem of two 12V inputs to the arduino. I need to find a way to power the arduino consistently, yet also allow for a way to reset it. I don't see this as a problem, just something I haven't figured out yet.
Also, I still don't have a solid state relay for the 110V power. I'll be picking that up this weekend. With that I'll get the automatic charging disconnect working which IMO is the more major part. Shortly after that, I'll hopefully get the automatic dc to dc converter disconnect setup and working.
