Do I have to charge new batteries?

Always charge before first use. New LFP/LiFePO4 batteries are subject to international transportation limitations and may be delivered with a 30% or less state of charge. Batteries fitted with resettable overdischarge protection may be delivered in 'sleep mode' i.e. power to the positive terminal has been internally disconnected i.e. no voltage will be measured at the battery terminals/posts. During storage the battery may have lost further charge.

How do I select the correct program?

To make a charge mode selection press and release the button once for Pb, twice for LFP or three times for 60'. Continuing to press and release the button in rapid succession will cycle selection from Pb through to 60' and then back to Pb. If no further selection is made for 3 seconds the last selected mode LED brightens to confirm selection is now final.

NOTE: If no selection is made 60sec. following connecting a battery for charge, the 60' mode activates automatically. To change selection, disconnect the battery, wait for the program to reset (confirmed when all LEDs flash together twice) and then return to a). Alternatively, turn off AC SW1 to reset all charge banks / stations

Can I charge series connected batteries with a multi-bank?

Yes, even if the batteries are connected in series they can still be charged without being disconnected from each other. Connect a charge bank to each battery individually, as if the batteries are not connected to each other. Each charge bank works independently with only the battery it is connected to.
