ABOUT THE J35 BMPRO’s range of J35 battery management systems management system are specially designed to be fitted in Jayco caravans. The J35 operates from 240V AC mains power supply, towing vehicle auxiliary and solar panels to simultaneously power caravan loads and charge the caravan battery.
9 Gel The J35B-L and J35D are also compatible with lithium LiFePO4 batteries. By default, the J35B-L is configured to charge lead acid batteries, and the J35D is configured to charge LiFePO4 batteries. WARNING Ensure you check your battery configuration before use.
DESCRIPTION OF PARTS Figure 1: The J35 MAINS CABLE The J35 is pre-cabled with a permanent mains power supply cord. The AC mains input is protected by a quick acting, high breaking capacity type fuse (rated 250V, 10A). LOAD TERMINAL BLOCK – COMMON NEGATIVE CONNECTION Negative wire connection point for the caravan’s 12V loads.

INSTALLATION INSTRUCTIONS MOUNTING THE J35 The J35 should be securely mounted to a suitably rigid surface, using four pre- drilled mounting holes. The preferred orientation is with the load connection at the bottom.It is recommended the mounting holes are located so that there is a minimum of 80mm free air space from all vented sides of J35.
CONNECTING A BATTERY TO THE J35 WARNING Sparks have the potential to cause an explosion should combustible gases be present. The following procedures are designed to minimise the risk of spark generation when connecting or disconnecting the battery. The positive terminal of the battery must not be connected to the chassis.
WARNING Do not install a battery in the same compartment where flammable material, such as petrol, is stored. Figure 3: Connecting a house battery to the J35 After fitting a new battery to the J35, make sure that it is configured in the JHub App.
CONNECTING MULTIPLE BATTERIES Before connecting multiple batteries in parallel to the J35, check that all batteries are: 9 Of the same type, for example, deep cycle AGM battery. 9 Of the same capacity, for example, 100Ah. 9 By the same manufacturer. ...
Battery Charging The J35 can simultaneously deliver up to 20A (J35A) or 35A (J35B-L, J35D) to the caravan battery and loads from the mains input source, with a maximum charging current of 15A (J35A) or 30A (J35B-L, J35D).
LVD MODE LEAD ACID LiFePO4 (J35B-L and J35D ONLY) Sleep Mode 10.8V 12.0V Storage Mode 10.5V 11.5V Table 6: LVD Mode voltage thresholds The J35 will enter the two stages of LVD, Sleep Mode and Storage Mode, when the caravan’s battery voltage falls below the LVD thresholds.
The J35B-L and 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 J35B-L or J35D will provide the voltage to restart the LiFePO4 battery’s BMS and then commence charging of the LiFePO4 battery.
PAIRING WITH THE CONTROLNODE To pair the ControlNode to your own personal mobile device: Make sure that the ControlNode is connected to the J35 and that the J35 is powered on. Turn on Bluetooth on your own personal device Press the Pairing Button on the ControlNode. The LED Status Indicator on the ControlNode will flash green, indicating you have 30 seconds to pair to the ControlNode.
SERVICING, MAINTENANCE AND STORAGE SERVICING The J35 and ControlNode contain hazardous voltages and energy hazards that may cause death or injury. Only qualified service personnel may service the J35 or ControlNode. Except where stated in the following sections, do not attempt to service the J35 or ControlNode yourself, OR dismantle, modify or repair the J35 or ControlNode yourself;...

BATTERY CHARGING MANAGEMENT ALGORITHM The following describes the Battery Charging Management Algorithm used by the J35 when charging the caravan battery from a mains power source. The J35 will operate as described when the caravan loads are connected directly to the J35 and not the caravan battery.
Charging current is maintained at 10A until the battery voltage reaches 12V or soft start timeout (see table 7) occurs. Boost Mode (J35B-L and J35D) During Boost Mode, current is boosted to 30A to bring the battery voltage up to 14V, after which charging proceeds to Bulk Mode.
