Newmar BI-100 Battery Integrator [BI-100]BI 100 Battery Integrator Charging multiple battery banks without the use of diode isolators dictates that the batteries be connected or integrated only whenever a charge voltage is present so that they may be charged simultaneously, then disconnected or isolated when the charge voltage is no longer present to allow for selective discharge and avoid having the secondary or standby battery drain into the primary battery. Battery integrators perform
