Capacitor in parallel with battery for high current output
Even "directly in parallel with the batteries" isn''t really directly in parallel with the batteries, thanks to wiring resistances. The capacitor should have the closest and most direct connection to the load, then this pair should be connected to the battery via wiring which gives you some control of the current drawn from the battery.
