Compatible Battery Monitors

• JHub Incl Control Node
• JControl Digital Caravan Battery Monitor

Key Features

• 14 x 12VDC outputs
• 35A maximum output current
• 30A maximum charging current
• Solar 28 Amp
• Lithium (LiFePO4) compatible

J35 Model D is lithium compatible power and battery management system. It features a built-in solar regulator and a multistage battery charger to ensure long battery life.

Use J35D battery management system to charge all lead-acid and lithium (LiFePO4) batteries. The J35D  allows charging of battery banks of up to 600Ah in capacity.

J35D allows you to charge the caravan battery to the optimal charge level from 230-240 Volt mains, your solar panel (28 Amp, or three panels 450W total), or any auxiliary input, such as a power generator or your vehicle.

J35D will increase the life span of your battery thanks to the multiple battery protection features, such as low voltage disconnect, storage mode and multistage charging.

DC Applications

There are 14 outputs to connect your DC appliances, including hot water, water pump, lights, and many more. Built-in electronic fuses protect the loads.

Built-in the top of the range Jayco caravans,  the J35D can recover and charge a heavily discharged LiFePO4 battery. The internal Battery Management System (BMS) of a LiFePO4 battery will turn off if it detects that the battery is heavily discharged.

The J35D will provide the voltage to restart the LiFePO4 battery’s BMS and then start charging the LiFePO4 battery.
