Connecting different batteries together

I have two Rigid 18v 3ah lithium ion batteries, 1 Dewalt 18v 2.3ah ni-cad battery, and 1 Worx 18v 1.3 ah lithium ion battery. Can I connect them together in series to make 72 volts? I know it's not good but I will use them for very short periods of time- like 20-30 seconds. I think it's OK as long as the battery with the smallest capacity doesn't get drained.

You SHOULD be alright. The load can't be too heavy either. I wouldn't exceed one amp.
