Did I kill my driver?

So finally got my parts to build my first laser have been wanting to for a long time.

Parts list:

Diode:NUBM06 450nm Laser Diode In Copper Module W/SXD Driver & 405-G-2 Lens

Driver:4A Super X-Drive(SXD-V3)

Batteries: 2 18650 lg


So I wanted to do a quick test to see if it works so I put the two batters in series and wired the driver to the batteries and it turned on but only left it on for 2-3 secs at the most since I don't have my heat sinks installed on driver and diode yet I tested it s few more times but I accidentally put one battery backwards and it kinda sparked when I touched the wire to the battery then I realized I had a battery backwards I corrected it but it never came back on :/
