GenAce Tattu 25c 22,000mah 6s1p

(I do the same for ALL my battery test. I bring it to a hover throw it in GPS mode and relax.)
I have been wanting to test these new batteries from GenAce for some time, I was lucky enough to get my hands on one of their 22,000mah packs.

I wanted to break this battery in correctly and watch the IR stabilize. I started by running the pack through the usual 10 break in cycles taking it down to 50-60% each time.. I noticed by these first flights that the battery was not sagging and cells seemed to be perfectly matched.

Below is the dataset of my 20th flight on this pack, this flight I took it down right to the 80% mark. Got close to 17mins of flight time on a fully loaded s1000 with GH4 HD Gimbal.I put back 17430mah in the pack, so at these flight times you will not be damaging this pack.

What I first noticed over any battery I have tested so far is how tight each cell is on the voltage loss. You will notice that it's a very tight curve and cells look to be closely matched. You will also notice how little sag there is, these are premium cells. IR has settled right at 5ohms which is very low!! The pack weighs 2509g (5lb 8.5oz), so even though these are top of the line cells, they have solid power to weight ratio as well.

If you're looking for that BIG pack to get you over the 16min mark, this is a great choice. These packs are pro level and the cells do show this. I know it's been hard to get these larger packs in the US from Tattu but that should not be an issue anymore! You can now order direct from GenAce/Tattu US,

Pack dimensions & weight :

Good to hear you like the Tattu packs. I use the 16,000 on my S900 and the (2) 22,000 on my heavy lift octo

Are you familiar with this company? The price for their tattu batteries seem low compared to others. I'm afraid of buying re-packaged batteries.
