The RV-12iS electrical system is a 12 VDC, negative ground system equipped
with either an EarthX Lithium (LiFePO4) (iS) or Odyssey lead/acid dry cell (ULS) style
battery mounted on the forward right side of the firewall. The generator operates only
while the engine is running. The generator supplies power to the regulator, which serves
the primary aircraft power system and charges the battery. The primary aircraft power is
a 30 amp fused circuit. Lights, servos, fans, avionics, and control switches are all fused
secondary circuits and part of the primary circuit.
