I am building a mobile watering/fertilizing tank for my wife. It is a 15 gallon plastic tank and I want to use one of my Ryobi 40v 6aH rechargeable batteries as the power source. My submersible pump is 12v 1.2a max and I am trying to figure out what specifications my buck converter should be to meet my needs. I am looking at a sealed buck converter with input range of 8v - 40v and an output of 12v 6a but is the 6a output too high? I cannot find an off the shelf buck that is sealed with an output of 12v 1.2a. I can find one with input of 8v - 40v and output of 12v 3a...would that be better?
