What type of rechargable battery are you currently using? Have you tried lithium ion? Those are rechargable, and I've sourced more than enough voltage with the 2/3 AA type. In fact, if the voltage is too high with a single battery like that, you may need a regulator to prevent burning out the flash. I think that part is rated for 3.3 volts max.

Well, the rechargeable batteries haven't enough voltage (1.2-1.3V) but really good current (80-90 mA each one, but in series, so it is the current of the sum..), the normal batteries have good voltage but not enough current (only 20-30 mA)..and i need minimum 2.7 V and 70 mA for the flash usage. Is there anyone who has solved this kind of issue? And also on the programming board i can source 5V but only 30 mA... Any suggestion is really wellcome!
