It's a little hard to tell without being able to see what the wires are connected to. There should not be any batteries in the flash. On the SB28 flash the AA batteries are connected in series. So, dummy batteries are in the ends of the battery compartment. One for positive and one for negative. The Camtraptions flash could be different. Plus your EBL batteries are 1.2 volts each. Two in series would be 2.4 volts. The four AA batteries total up to about 6 volts. Or, are there four cells in the battery holder?
