Sadly I am not quiet sure which battery it was exactly but it had about 5000mAh. Two of those were fitting perfectly without any space left. I think it was the 5300mAh version but I cannot proof it since I am unable to find the website which gave me the tipp back then.

Darn. As I prefer Gens-Tattu to any other Chinese brand, when testing alternate batteries I spent a lot of time researching their catalog for batteries with dimensions that would allow fitting two with reasonable capacities. Some of us even contacted them directly to inquire about making batteries for the 920 for U.S. users. Both efforts failed.

We might note Tattu had been producing 920 batteries for the Euro/U.K. that were not distributed to the U.S., nor would they ever be, but they even discontinued those due to low sales volume.

Replacement battery for H 920
I was on the phone today checking on some different options for my h 920.
I was told that the h 920 was the smallest platform that a fuel cell could be used on.
I was given a price that included the tank for hydrogen,and all components to bring my yuneec up date with hydrogen world.
the sales pitch included such things as 4 times the flight time as compared to a battery, ease of locating hydrogen and finally you could swap out the tank in under 3 minutes.
everything sounded very good but the problem is do I want to spend 9000.00 on a system that I might not be able to purchase replacement parts for.?
It is indeed unfortunate that Yuneec let its customers down on this model some times it is better to look for equipment that will be better suited for our needs and just let the h 920 quietly die.

Sort of like shooting your horse because it reached the grand old age of 3....

There are quite a few batteries available that can be fit as a pair in a 920 or 920+. The problem for some is obtaining the maximum capacity, or in trying to match the capacity obtained with 3 Yuneec factory batteries.

We should recognize 3 factory batteries with a total capacity of 12,000mA is only available from Yuneec. A problem arises as the factory batteries are old even when brand new and do not perform as they should. It has been repeatedly found the a pair of decent 5000mA 25C batteries meets or exceeds the flight time performance of 3 factory batteries. Even a single 8000mA battery in one chemistry can match a set of 3 factory batteries.

So a solution is simply obtaining a pair of 6S batteries of suitable capacity, say 4000 to 5400mA, that can easily fit inside the 920 battery compartment. Don’t stress achieving extremely long flight times. More concern should be given to obtaining consistent and safe flight times regardless of what that time might be. The capacity of the batteries selected will determine how much time you can obtain. A few flights with the batteries of choice will tell you what that average time will be.
