1. Most chargers use individual buck converters, unlike the OPUS, so it shouldn’t be a problem.
2. Great.
3. Temp sensors right beside the terminals. At max power(charging 4x30Qs at 12A total), the C4-12 doesn’t get too hot. It’s the cells getting hot, so monitoring cell temps is more important than the electronics’ temps.
4. Great.
5. Same thing as number 3.
8. Would be very nice, and would make inaccurate internal resistance measurement a thing of the past, most of the time anyway.
9. Great.
11. Great.
12. Storage charge mode would just charge/discharge the cell down to 3,6V. I would really like a it down to 3,4-3,5V, but 3,6V is a happy medium.
15. Yes, from 2,6V-3,3V. 3,7V is rather high. What would you want to do with it?
