| A b2b (or //dc-dc//) charger is a type of [[electrical:12v:alternator|isolator]] that boosts charging voltage to the house battery. These typically cost more and deliver less current than normal isolator types | A b2b (or //dc-dc//) charger is a type of [[electrical:12v:alternator|isolator]] that boosts charging voltage to the house battery.

| | The most common example is the [[https://amzn.to/2RY2GNQ|CTEK D250SA]], a 20A solar/alt controller. The [[https://amzn.to/2TozjWu|SmartPass accessory]] bypasses the D250SA when the house battery wants > 20A of current. This will generally happen in the first half of Bulk mode. When the house battery demand drops below 20A control is handed back to the D250SA for boosting to Absorption voltage.((https://www.4x4community.co.za/forum/showthread.php/292297-Ctek-250-upgrade-to-smartpass?p=3823781#post3823781))\\ |
