Does anyone know if off brand batteries are just as good, and if changing to a higher mah such as from 4000mah to a 5000mah battery helps in longer flight times. Just bought the 920 plus and trying to a couple sets with out breaking the bank.
Measure the batteries laid out as they fit into the bird together length, width height.
Believe the front to back length is 167mm
width (l-R) is 98/99mm
height 46mm
There are many 6s 22.2V 4000Mah + batteries with these nominal dimensions as a set of 2.
So 1 battery would be;
167mm long
45-49mm wide
45-46mm tall
There are 3 plugs, since this is wired in parallel the voltage is constant, 2 batteries in the cavity will be adequate.
There is a video on you tube (In German)of a H920, that did a flight test with 2 6S batteries.
Here is a battery that will fit into the H920 compartment;

For these you would either replace the plug with an EC3 connector or get an adapter...
These are just "suggestions" do a generalized search for 6s 22.2V min. 4000 Mah LiPo batteries, surely there will be a plethora of options...
