FAQs

The ability to configure battery chemistry is available only if the JControl is in use with the J35B-L or J35D, which are capable of charging both lead acid and LiFePO4 type batteries.

By default, the J35B-L or J35D are configured to charge lead acid batteries. This can be changed with the JControl monitor.

To configure the J35B-L or J35D to charge LiFePO4 batteries with the JControl monitor:

  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 ADVANC menu function.
  3. Navigate and select LiFePO4.

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.

A factory reset of the JControl can be performed if the device is not working as expected.

To perform a factory reset of 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 FACTRY menu function.
  3. Follow the directions in the below image to perform a factory reset of your JControl.
