- Page 2 The auxiliary battery bank can be split charged from the engine battery bank via a split charge device whilst the engine is running. To do this, the control switch must be in the ‘12V’ position. It will not split charge the auxiliary battery bank if the switch is in the ‘Off’ or ‘24V’ position. Merlin recommends use of SmartBank Pro as a split charge device as this can be inhibited when Jump Start Box is operating in 24V mode.
