Page 5: Installation
Sensor measures temperature at the battery, allowing the DC- DC charger to use this data for accurate temperature compensation and charge voltage adjustment. Improve your battery charging system with a Renogy Temperature Sensor. No temperature compensation when charging lithium battery. - Page 6 When selecting a location for the DCDC, make sure that the unit is as close as possible to the battery you will be charging (auxiliary battery). The charger may be mounted on the cabin of the vehicle, along a chassis rail, the inner guard of a vehicle, behind the grille or headlight or even on the side of the radiator.
- Page 7 Figure 2 Cable Cross Section *The following is a reference and may not cover all the unique applications that may exist. Consult your installer for further questions. Important Note: When the battery charger is sending full amps, the input side will experience a higher draw.
- Page 8 Connecting the Battery Charger The DCDC will not turn on without a D+ ignition cable. When connected, the DCDC will turn on when the ignition is on. This means that even if your engine is not on, the starter battery will immediately be used to power the DCDC and start charging the house battery.
- Page 9 Important Note: The Alternator will not be connected directly to the input of the DCDC. The alternator must be connected to the starter battery and from this connection there will be a bus connection to the input of the DCDC. See Figure 3 Figure 3 Figure 4 3.

Page 10: Operation
Caution: The DCDC will turn on when the ignition is on. This means that even if your engine is not on, the starter battery will immediately be used to power the DCDC and start charging the house battery. It is recommended to have the vehicle completely on. IMPORTANT: A D+ ignition cable is required to turn the unit on. - Page 11 Setting Battery Charger Please Note: The battery charger is for lithium-iron phosphate battery types with a built in BMS system. Do not use the device under any circumstances to charge other types of batteries (ex. NiCd, NiMH, etc.). WARNING: Danger of Explosion! *Note: Check the charging requirements from the battery manufacturer before charging your battery with this unit.
- Page 12 SW5 ON If SW5 is set to ON, then you will follow the lead acid charging profiles in the following charts. SW1/SW2 will determine the desired absorption voltage and SW3/SW4 will determine the desired float voltage. *Please note that the charging profile will automatically bulk before approaching the user-defined absorption and float stage.
- Page 13 SW5 OFF Please Note: The battery charger is for lithium-iron phosphate battery types with a built in BMS system. Do not use the device under any circumstances to charge other types of batteries (ex. NiCd, NiMH, etc.). If SW5 is set to OFF, then you will follow the lithium-iron phosphate charging profiles in the following charts.
