Ok, I came back from SecondLifeStorage, and I have some new ideas. Last features to be implemented.
@TheOnlyDocc, you came before I did. You know about 7S lithium ion battery packs? Their max voltage is 29,4V, a (5V-10V)–30V compatibility would be excellent.
@adam7027, that would be insane below 0,3A, but I get your idea.
1. Here is how I would prefer doing it:
0,05A
0,10A
0,20A
0,30A
0,50A
0,70A
0,80A
1,00A
1,20A
1,40A
1,50A
1,70A
1,80A
2,00A
2,20A
2,50A
2,75A
3,00A
2. That includes NiZn.
3. NiMH charging will throttle below 2A if it gets too hot(above 45C), and if it exceeds 60C or 1,75V, it will completely stop charging.
4. 10180 support is planned.
5. Nooo. Only one 90/120mm fan would be best.
6. These maximum charge rates have only been tested for 18650 cells.
You can set them lower obviously. Your current targets are way too low.
7. No, not exactly.
It should be: 3,5V-4,35V in 0,05V steps for all chemistries.
8. Storage mode does exactly that.
9. 4 button UI.
10. Ok for discharge rates.
Sorry if it took some time. I’m writing this on a phone.
