Battery System Configurations

Illustration in preparation Description: Two-battery parallel wiring with isolator relay: alternator → primary battery → isolator relay → secondary battery; power distribution from secondary to amplifiers; isolator control wire from ignition; fusing shown at each battery

Illustration in preparation Description: Four-battery bank: all positives connected via heavy busbars with individual fuses, all negatives to common ground bus, main output to amplifier distribution block; wire gauges labeled (0000 AWG interconnects)

Parallel battery rules (visual summary):

1. All connecting wires equal length
2. All connecting wires equal gauge
3. Each battery individually fused
4. Isolator between primary and secondary bank
5. All grounds to same point
