So heres the theory behind my dual smart battery setup. I haven't flown yet, because the project has a bit of work to do before its complete, but the bench test snows that with two equally charged solo smart batteries spliced into the same power header, and same SM bus header, solo has no clue there is a second battery. My hypothesis is that it will make it's calculations based on the overload of SM-bus info (both batteries being repetitively queried) and therefore just think the battery is performing as normal, when in fact, there are two.
I'm no expert in the sm-bus architecture, but I believe it works on a simple get-request architecture and when requesting information, the battery to respond first will be the data it uses. If the two are responding simultaneously , this should result in the solo main board inadvertently running smart battery logic on the cumulative of both sm bus responses....... very similar to if you dump two watering cans into a 5 gallon bucket. Say one is slightly lower than the other, solo will take that information into account, and then when the better performing battery responds, it will think the performance improved a little and go back up.

I have bench tested this, and it seems to work, but I wont know for sure until I get this bad boy up in the air. The goal is a clone of the Inspire 2. dual batteries and all, even though they arent 6s.

Wish me luck guys!
Here's a test video of the 2nd batt in parallel on my rebuilt Solo.
Read the comment section in my YT video for Flight time improvement. No need for arduino. Use pause button and rc7.Awesome Andru. How much longer overall was your increase in flight time with the larger props/motors and dual battery setup? And also, did you need an arduino to setup the retractable landing gear? if so, what pins did you tap into? that is my current struggle, figuring out which pins to wire my Servo into.

I am not much of a speed demon so no i will not be testing it.Nice Andy, I know the one guy was asking about performance in your comments, did you notice a top speed increase? Or would this be something you would be willing to test? I know stock solo Almost hit 35 on a calm day.
