casainho - just about to test the WH feature on the LCD3, here's a short writeup of my understanding of the secondary menu (quickly looking at your code markups)
Hold POWER to get into the secondary menu
0 state (UP/DOWN to disable (0) or enable (1) WH display in lower right-hand corner) POWER for next menu item
1 state (UP/DOWN for incrementing (WH used so far) (0) or decrementing (1) (WH left in battery) ) POWER for next menu item
2 state (UP/DOWN to set WH at 100% SOC of battery) POWER for next menu item
3 state (UP/DOWN to set current WH of battery) POWER for next menu item
for this last menu item - wouldn't it be easier to just ask for AH of the battery and then multiply it by the current voltage? I haven't taken a look at all the code, but this seems like the simpler and more accurate solution.
Excited to try this out - will update!
After entering in the configurations menu, the submenu 1 (submenu 1: battery whatt hours configuration):
0. enable/disable WH display in lower right-hand corner
1. WH display counting up or counting down
2. WH at 100% SOC of battery
3. set current WH of battery
The 2. value is automatically reset to zero if LCD3 is start up and battery voltage = 54V (battery fully charged).
I see 3. to be only used when you exchange batteries and on that case you should take note of WH you see on display. Or like what is happening on one of my battery packs that is not yet fully balanced and it do not reaches the 54V yet and so I need to reset WH manually.
I must say this feature is working perfectly!!!
