This disclosure describes techniques that support delivering electrical stimulation current via at least two user-selected electrodes of an implantable medical device (IMD) and automatically delivering balancing current below via at least one non-selected electrode. Balancing currents delivered via the at least one non-selected electrode may be configured with an amplitude below a perception threshold of a patient. Delivery of balancing current via the at least one third electrode may allow an implantable medical device to automatically balance the total current delivered to a patient.
