If you have the flash set to full power, the batteries are fresh and the flash interval is set too short and too many activations happen, the flash can over heat. So, it is important to have a camera controller that you can set a delay between flashes and set the maximum number of activations per motion event. This gives the flash time to recharge the flash capacitor and not over heat. Typically you don't need to run the flashes at full power. With the newer DSLR cameras able to shoot at a little higher ISO without noise, you don't need as much flash lighting.
Thank you Jeff. Fortunately I can manage with 1/128 or 1/64. Sometimes I might want flash multi mode.
I used a 6V4.5A external battery to power up my Yongnuo 568 EX III flash using above technique. Flash started heating up within seconds that it nearly melted the plastic adapters. But didnt fry the flash. What could have gone wrong 20200514_153308_mfnr.jpg

When did you notice the heating of the plastic? Was it while activating the flash? What part of the plastic was getting hot?
It was while I was turning the flash on. Actually the flash didn't turn on.Parts along the positive terminal were heating up. Specially those connectors (1and 2 in figure) were nearly melted.red wire is the positive.20200514_213128.jpgOriginally Posted by -jeff
Looks like someplace in the circuit was drawing a lot of current. Check the placement of your plastic inserts in the flash. Make sure the polarity is correct and that the inserts are in the right holes.
Thanks Jeff. However yesterday I could turn on the flash for a little while with newly bought battery. Then I fully charged the battery today and tried and then this happened. How to decide whether inserts are in right holes properly? Here is a clear figure shiwing the holes.15894733099786648542138879892425.jpg
Without seeing the bottom of the battery compartment it's hard to tell which slots your plastic tubes should be in.
