This is a very good deal, although heavy because of old cells. They say Samsung cells so with 12s10p 25Ah, it is most likely a 25R cell with 20A each, so total 200A for the pack . Do you know how much cont/max current the BMS can handle? The capacity should be about 1kW; anyone verified this number? Just worried if these are old packs with reduced capacity due to shelf life.
How about the waterproof connector. Is it custom or can it be ordered on Ali etc?
@Youpi : I did buy the same hardware : Takuma battery, ESC FT85BS, W6 and 6384.
However, the speed is not enough to take off. Maybe it come from the propellers or from the setting on the FT85BS. Which max current did you set in the ESC ?
Did you find good propellers design (with one inverted ?)
