A system balances current flowing through a solid-state power controller system including at least two output channels connected in parallel. The system delivers a first current to a load via a first output channel to a load, and delivers a second current to the load via a second output channel connected in parallel with the first output channel. The system further determines a first strength of the first current and a second strength of the second current, and adjusts at least one of a first resistance of the first output channel and a second resistance of the second output channel such that the first current strength is substantially equal to the second current strength.
