I purchased my Tattu batteries from Michael. Great price and service and the batteries are working great.
Hi there, just to propose you an other option, for couple of month i'm working only out of my country so choose some 4500 gensace so under 100w for traveling in plane and quite versatile as I can use 2 or 4 depending of my needs, as example flying at 3900m getting 10,1kg with A7SII metabones and ZEISS. had a confortable 7"30. landing at 21,8 loaded!
