Renogy note that most lithium batteries do not require temperature compensation, and that a LiFePO4 pack charges safely between −20°C and 55°C with its own BMS reducing or stopping charge current below 0°C. If your bank is lithium with a working BMS, this sensor solves a problem you do not have. If it is AGM, gel or flooded, it solves a real one.\u003c\/p\u003e\u003ch3\u003eWhere it makes a difference\u003c\/h3\u003e\u003cp\u003eA lead acid bank in an unheated locker spends the winter being undercharged, because the controller is targeting a voltage suited to a warm battery. Compensation corrects that, and chronic undercharging is the single biggest killer of lead acid banks in vehicles.\u003c\/p\u003e\u003ch3\u003eBefore you order\u003c\/h3\u003e\u003cp\u003eCheck the controller: this is the Voyager-specific sensor, and the Rover, Adventurer and Wanderer controllers take the other one.
