I am using 2100mah LSD batteries - an Eneloop clone. So the variance in power should be less. All the connectors will be soldered.
The 3.6V will hopefully give enough of a leeway.
The cameras will fire 40ms after each other. So hopefully the peak current draw will not be more than 20A as the camera draws max power when saving the image to flash.
Otherwise the Review is off, AF and related functions are off, flash is also off. Lets see how it goes..
On another note do you know the technical part num for the 0.7 * 2.5mm plug ? The Maple numbering seem to be specific to their site..
