 In many/most situations, direct-charging the house bank with [[electrical:12v:alternator#combiners|a combiner]] (relay, isolator, VSR)  is both effective and inexpensive. Even [[electrical:12v:directcharginglfp|with lithium banks]].
-However, some advanced situations may require a **DC-to-DC charger**. These are much more intelligent (and expensive) devices that sit in between the vehicle batteries and the house batteries, and actively adjust both the voltage and current flowing from the vehicle's electrical system and into the house batteries.

 ===== Situations where DC-DC is preferable =====
-  * when the alternator is the sole charging source for LiFePO4((DC-DC will deliver more consistent and //usually// faster charging in this case))
+  * when the alternator is the sole charging source for LiFePO4.  In this situation DC-DC will deliver more predictable and often faster charging, particularly when the bank is at higher SoC.
