I lost my software CD. Is there anywhere the software can be downloaded?

The USB serial adapter use the FTDI chip, you can download a driver from FTDI website (Steps: http://www.ftdichip.com>“Driver”>”VCP Drivers”> choosing a corresponding system driver on the opened page). If you can't download it, please contact us by clicking "contact seller" of the order, we will send you a instruction file.

Will this work with 4 wire RS485 connections?

So far I use it for two wire, but if I recall correctly, when I got my first one (I've done repeat purchases) I did test it with a four wire setup initially. I think the instructions did show the setup, but you'll have to check to be sure.

Will this do 232 connection?

No, It won't. The USB to RS485 adapter you asked is for RS-485 or RS-422 connection. For RS232 connection, you may check DTECH RS232 serial cables below: 4ft USB to RS232 cable (FTDI chip) --- http://www.amazon.com/dp/B00H8HDS2K 10ft USB to RS232 cable (FTDI chip) ---- http://www.amazon.com/dp/B017D51ZRQ Thank you very much!

Will this work with valence lithium ion battereis?

I'm not clear what you are asking. This device is powered by the USB port on the computer that it is plugged into. No batteries required. Can you tell me more about where the lithium ion battery is located in your situation? Are you trying to power this with a battery, rather than the computer's port?
