What do I have to do with my JControl if I add another battery?

If you have added a new battery, you will need to set the battery capacity on your JControl to show the total battery capacity. By default, the battery capacity is set to 100Ah.

Correctly configuring the battery capacity ensures that the J35 will select the best charging parameters for the caravan battery in use and the software accurately estimates battery usage including Battery Capacity and Time Remaining.

To configure the J35 battery capacity with the JControl:

1. Enter Set-Up mode by holding the SETTINGS button down until Set-Up is seen in the AMPS and VOLTS display.
2. Navigate to the BATCAP menu function.
3. Follow the directions in the below image to configure the water tank type on your JControl. 

The battery capacity can be adjusted between 50 and 600AH in steps of 10AH.
