Product Q&A
-
Can I change the amp output of the charger?
No, the amp output can not be changed. You will need to confirm that the charger you purchase will not produce more than your battery max input

-
What is the purpose of a DC to Dc Charger?
Installed between the house battery and the starter battery is the DC-DC battery charger. It takes energy from the start battery in the vehicle and adjusts the voltage to match the requirements of the device being charged ie house battery
-
How can I pick a battery charger that works well?
1. Verify that the system is running on 12 volts throughout.
2. Make sure that the DC-DC battery charger's maximum charging current does not surpass the maximum charging current that the house battery permits.
-
How can I adjust the charger to charge different chemical batteries?
The DIP switch concept is included into the DC-DC battery charger. There are 5 dip switches that need setting based on the profile of the battery. Please refer to the manual for the correct setting for each profile.
-
Do I need to connect the included D+ ignition cable?
The D+ igntion cable is necessary to install as the Dc-Dc charger will not power on until it detects the 12v source from the vehicles alternator. This is also to prevent the Dc-Dc chargerfrom drain the start battery when the vehicle is not running.
