Wires connecting a battery to a motor in an electric car has a resistance of 0.005 ohms and the battery supplys 6kW.

I have '28' 6V batteries.

Should I connect them in series and risk a dangerously high voltage or would it be better to put them in parallel.

Tips:

i. You may wish to look at total voltage in each case
ii. The total current flow in each case and the energy lost per second in the wires.
iii. Also comment upon efficiency.

Comment and advise on each situation.
