Truthfully I'm not really sure and haven't given it too much thought. This is just a fun and challenging project and proof of concept at this point. I've even ordered a 3D printer to build the housing with almost a cubic foot of build area lol (I have many other uses for it as well).Way cool, so do you plan to sell these?
See this post for the Battery Charging connector (without data port). They are the same as the charger plug that comes with the solo except there isn't the additional black tab to keep the plug orientated: Hitec X4 AC Plus Four-Channel AC/DC Multi-ChargerIs there a known source to buy just the connector for the primary +/- terminal? I'd like to pick up a few to make my own cables for charging multiple batteries off my big ass power supply.
I can't answer that definitively, but personally I wouldn't try that without CC/CV. The battery does have some protections built in, but I don't know what it would do with a 30A load. I've heard the battery limits itself to a 5.2A input current, but don't quote me on that. My CC/CV power supply hasn't gotten here yet to test various charge loads, but the one I ordered will do up to 20A/350W max so I can experiment with larger lipos (when they come outWill the battery self-regulate the recharge rate? In other words, I have a 16.8v 30 amp power supply. If I just plug it in directly, will the battery allow itself to recharge too fast? Or will it only allow itself to charge a safe rate? I can always use my balance charger in non-balance mode to limit current if needed.
Here is where the PX4 firmware is getting the data from the battery: PX4Firmware/batt_smbus.cpp at master · diydrones/PX4Firmware · GitHub
There are a couple arduino sketchs I've come across that let you reprogram the smbus module but I don't have an extra battery yet to crack intoNow to figure out a way to get a larger capacity, lighter battery to work.
I'll take a look at this code, thanks for the information.Here is what I started with:
PackProbe Documentation
Runs fine on an Arduino Nano.
Be sure to pull up both SDA and SCL to the nano's 5V and connect the Battery - to the nano's ground.
Using this information I was able to modify this code and read data from Solo Batteries.Here is what I started with:

I tried it again. Had a fully charged battery powered on, and could not read any data from the battery. I placed the battery on the solo and let it drain to 95% and then put it back on the arduino, and I was able to read data.
