What example code did you use? i am using rpi3 with the adafruit example code and can't get the device to come up with i2cdetect -y 1?

You should check if you've got it wired correctly (Vcc to RPi 3.3v, SDA to SDA, SCL to SCL, and GND to GND). Also ensure you're wired to I2C Bus 1 (pins 3 and 5) and not Bus 0 (pins 27 and 28). Also double check that you've enabled I2C on your pi and, if possible, works on a known good device. You could also double check your soldering. If everything checks out, your ADC may just be dead.

Does this support multiple i2c addresses? can i configure them to use two of these with different addresses on the same bus? if so, how?

Yes, the ADS1115 supports multiple I2C addresses. I'm writing this from memory but I recall the default address is 0x48 and there is an addr pin on the device - tie the addr pin to VDD and you get address 0x49. Just lookup the data sheet on google all the info about using the device and how to set the addresses is in the data sheet. I did have a project, in the past, where I used 2 of these devices on addresses 0x48 and 0x49 I2C and everything worked fine. Hope that helps.

Can I run several of these on the same i2c bus, but with different ground references? I'd like to have one of these "per cell" in a battery string.

If your not using common ground with your bus then the signal that is being sent to the bus won’t be a closed circuit resulting in error.

Where do I find the schematic and sample code?

Adafruit has Arduino library and example code. Specification sheets can be found at www.ti.com.
