There is many options and manufactures to look at... First I will check what local stores (like YE, Partco and Elfa) are selling. I will make later decisions, what voltage converter to use. Because of efficiency requirements, converter module based on the linear technology, is not an option here...
requirements:
-typical input voltage 14.8…16.8V DC
-output voltage 12...13.5V DC
-output current 6A continuous
-efficiency bigger than 80%
-input low voltage cut-off @ 14V
=> 4*3.5V for 4S LiPo
-output short circuit protected
-preferred as PCB model
-small size recommended
-small heatsink usage - ok

how about this one - much cheaper in UK http://uk.farnell.com/multicomp/fdd15-12d1/converter-dc-dc-15w-12v/dp/1181182 seems to be about the same specs but 1/3 of the price
For my purposes, the output current of this model, is not sufficient. I have measured, that on the longer exposueres, Nikon D200 takes itself 0.6amps. (to be on the safe side, supply has to be rated at least 3 amps). I also plan to feed two other equipment (dew heater and tracking mount) for short period of use, so the current requirement increases...
There is some manufacturers and stores, that I have not yet checked (for cheaper option, compared to meanwell module)
