Tattu and Gens Ace are the same company, with the Tattu line being of a little higher quality, although the Gens Ace line is no slouch. For my heavy lift copters I'll only use two brands of batteries, Tattu and Max Amps. Quality wise both are extremely high and deliver high energy output for the rated capacity. I have 6s 7000ma Tattu batteries that weigh 30-60 grams less than most of the cheaper 6400ma batteries out there, and the Tattu's are also dimensionally smaller. When you have a copter that by itself will set you back $3k plus, and you have to build it, before you get to the camera and gimbal you take seriously what components you use, By the time you hang a DSLR, lens, a good gimbal, FPV and video down link equipment under it you've put close to $10k, or much more, in the air. A MoVi gimbal starts at $5k. It's pretty dumb to hunt down the cheapest battery you can buy when it will likely end up the weakest link in the system. When it fails you certainly won't have saved a dime.
If you plan on doing serious work, make serious decisions where your aircraft are concerned. More often than not it will be the difference between having a reliable system or one that ends up frequently in the weeds. Even at the level of the H, the difference between one battery and another can make all the difference in the world in keeping your aircraft. For as little as we pay for it the H is a pretty darn good tool.
