External dc power supply rating for BlueROV2

I would like to be able to power my BlueROV2 with an external power supply. This will make it easier for me to work on the development I have planned, without having to depend on the use of batteries.
The batteries included in BlueROV2 are 14.4Vdc and a capacity of 18A.
My question is what voltage I have to choose for the power supply, although I imagine that 12Vdc or 15Vdc could work, but what is the best voltage that I can select for the power supply?
Cheers,
Galo

Hi @luisgalo -
I use this 15V power supply when developing with the BlueROV2 or BlueBoat - it doesn’t supply sufficient current to run the motors, so doing so may lead to the vehicle resetting, but it’s great to not worry about keeping things charged. A 12V supply should also work!
These barrel jack to screw terminal adapters make connecting an XT90 to the device easy, and require minimal soldering…
