I did for the item number he listed, but got no item. If it is the usual lab style head it runs off +12 volts, so 3 Li ion batteries would work.

You could use an 18650 battery at 3500 mAh. Those are usually 3.7 volts loaded.

TTL input says 0 to 5V input. That's just the on/off for the TTL function

The driver runs on >2A, 12VDC
Just buy a cheap plug in wall AC to >2A, 12VDC transformer or any >2A 12V battery of any kind will do.

Would 8 AA lithium rechargable batteries in a pack be okay?

I also have an LED driver thats rated at 12v 8amps. Is that too many amps?

If you not just Trolling LPF with nonsense questions which increasingly seems to be the case:

The batteries you gave a link for specifically say they are not rechargeable.

You have the answers above.

The item clearly states what the electrical power requirements are.
If you can't figure out/comprehend how to power the item with a >2A , 12V power supply sufficient for whatever it is you want to do and/or have no idea of what you are doing, don't buy the item.
If you do buy it, observe laser safety procedures and buy good laser goggles/glasses to protect your eyes.

I took the OP at his word about input voltage. Should have looked more closely. Just use three 18650 batteries in series.
