I am trying to come up with a battery system to supply an electronic fuel injection system on motorcycle engine powered race car that will weigh less and last longer while giving it greater reliability to last the entire race. I did a little research and found these LiFePo cells that I can make my own battery with just wondering if I could use a buck converter on a 24 volt battery that I made to make the battery actually last longer because I only need a 12 volt supply to run my equipment
