A battery system includes a traction battery, a traction battery controller, and a backup controller. The traction battery powers a high-voltage domain. The traction battery controller may be powered by a low-voltage domain that is separated from the high-voltage domain. The traction battery may be configured to disable cell balancing of the traction battery after expiration of a main timer. The backup controller may be powered by and within the high-voltage domain. The backup controller implements a backup timer, that includes a non-processor logic circuit, and is configured to disable cell balancing after expiration of the backup timer.
