 ===== when to run opportunity loads =====
-**The best time to run non-essential loads is when there is surplus current** over what battery charging needs.  This means **during Float, or after current has started dropping off in Absorption**.
+**The best time to run non-essential loads is when there is surplus current** over what battery charging needs.  This means **during Float, or after current has started dropping off in Absorption**.  For [[electrical:12v:deep_cycle_battery#lithium_chemistries|LiFePO4]] there is excess power any time after the bank has reached the intended charge state.
 Opportunity loads should not be applied during [[electrical:12v:charging|Bulk stage]] since Bulk, by definition, means the battery is taking all the available current.((assuming no charging limit has been configured in the [[electrical:solar:charge_controller|charge controller]]))
-For [[electrical:12v:deep_cycle_battery#lithium_chemistries|LiFePO4]] set the LVD to Vfloat; there is no actual Absorption stage _per se_ in fractional-C charging. We use these setpoints only because our traditional lead-acid controllers work that way.
