BMPRO J35D Battery Management System – Replaced by ASPERO

The BMPRO J35D Battery Management System has been discontinued. For updated technology, please use the ASPERO Battery Management System from BMPro.

The J35D is a lithium compatible battery management system developed for Jayco Australia. It features an integrated solar regulator and a multi-stage battery charger.

This unit supports charging for both lead acid and lithium (LiFePO4) batteries and manages battery banks up to 600Ah.

The J35D charges caravan batteries from 230-240 Volt mains, solar panels (up to 28 Amp or three panels totalling 450W), and auxiliary sources such as generators and vehicle power.

Battery life is maintained with low voltage disconnect, storage mode, multistage charging, and built-in electronic fuses. The system provides 14 DC outputs for appliances including water pumps, hot water systems, and lighting.

The system can restart the internal Battery Management System (BMS) to recover heavily discharged LiFePO4 batteries before charging.

Compatible with JControl monitors and the JHub app for live monitoring and control of your caravan’s electrical system.
