Multiple drill batteries to run pump?
Post Body
I want to run a 150 watt dc pump that draws a max of 18amp. I want to run the pump with 20v drill batteries with a C rating of 1 and 4 AH. If I understand the math 1(c rating )x 4(AH) x V(20) that makes my wattage output 80 per battery . Obviously I need 150 watts to run the pump. Can I hook two batteries together in parallel to get that wattage ? I understand that I will need to step the voltage down to 12 volts but any advice on the whole setup is appreciated .
