ABOUT THE BATTERYPLUS35-II BMPRO’s BatteryPlus35-II is a battery management system designed specifically for use in recreational vehicles. The BatteryPlus35-II operates from 100 to 240V AC mains power supply, towing vehicle auxiliary and solar panel to provide 35A of current to simultaneously power caravan loads and charge the caravan battery. The BatteryPlus35-II is available in a range of models to suite any RV and battery management needs.
COMPATIBLE BATTERY TYPES The BatteryPlus35-II is rated to charge battery banks of up to 600Ah in capacity and of the following battery types: BATTERY Lead Acid Lithium SI SR HA* Valve-Regulated (VRLA) Yes Yes Yes Absorbed Glass Mat (AGM) Yes Yes Yes Gel Yes Yes Yes LiFePO4 No No Yes Table 2: Batteries compatible for use with the BatteryPlus35-II * By default, the BP35-II-HA is configured to charge lead acid batteries.
DESCRIPTION OF PARTS Figure 1: BatteryPlus35-II. Compatible for all models 1. MAINS CABLE The BatteryPlus35-II is pre-cabled with a permanent mains power supply cord for use with 240V or 110V input power. WARNING Do not replace a damaged power supply cord. If the power cord is damaged, the BatteryPlus35-II must be discarded. Ensure that the AC mains source always has an earth terminal. 2. LOAD TERMINAL BLOCK – COMMON NEGATIVE CONNECTION Negative wire connection return point for the caravan’s 12V loads.

To maintain good health of the battery during low voltage, manually turn these loads off.
INSTALLATION INSTRUCTIONS PERSONNEL Installation is to be carried out only by suitably qualified personnel. EARTHING As the BP35-11 is positive sensing for current monitoring, this allows for chassis earthing of both the battery and the negative of DC 12 V appliances. Note: All DC 12 V positive cables must be wired to outputs 1-14 or the 40A battery output connection.

VENTILATION, ORIENTATION AND THERMAL CONSIDERATIONS The preferred orientation is with the load connection at the bottom, as shown in figure 2: Recommended mounting holes and located such that there is a minimum of 80 mm free air space from all vented sides of BatteryPlus35-II. This allows for the lowest operating temperature of the internal electronics and the highest reliability of the product.
MOUNTING BatteryPlus35-II should be securely mounted to a suitably rigid surface, using four pre-drilled mounting holes. Dimensions are provided in Figure 3: Mounting Diagram. Figure 2: Mounting Diagram MAINS CABLE WARNING If the supply cord is damaged, it must not be replaced and the appliance should be scrapped. This is pre-cabled and fitted with a mains plug.
Wire Size DC cables must be sized to carry the maximum full load current and to not exceed the system volt drop requirements. The following cable sizes are recommended. When running wires, if they pass through panels or wall, ensure the wires are protected from damage by sharp edges. The use of cable glands is recommended. CURRENT MINIMUM WIRE SIZE 0-10A 1.0mm2 or 18 AWG 10-20A 3.0mm2 or 14 AWG 20-30A 5.
MAIN CHARGE CONNECTION The following inputs / outputs require fork type connections: Aux+ / Batt+ / Batt- / BRK+ Max. 8.2mm Min. 3.6mm Figure 4: Fork Terminal Dimensions CARAVAN BATTERY CONNECTION WARNING A fuse must be installed in the positive connection of the battery. This fuse MUST be as close as possible to the battery. This fuse protects against short circuits and reverse battery conditions. A fuse rating no greater than 40 Amps must be used.
REPLACING BATTERIES WARNING Before using a battery other than that which was installed at the caravan dealership, consult with the battery manufacturer for a detailed description of the installation, uses and maintenance of the battery. Verify that the type and capacity of the battery or batteries used are compatible for use with the BatteryPlus35-II. Figure 4 details connection of the caravan battery to the BatteryPlus35-II.
Disconnecting a Battery from the BatteryPlus35-II 1. Power off all loads connected to the BatteryPlus35-II, the easiest way is with the switch connected to the BatteryPlus35-II’s RSW input 2. Turn off and remove all power sources (auxiliary/mains/solar) to the BatteryPlus35-II 3. Disconnect the battery’s negative (black) terminal from the BatteryPlus35-II Batt- Connection Point 4.
USING YOUR BATTERYPLUS35-II INPUT POWER SOURCES The BatteryPlus35-II can charge from auxiliary, mains and solar input sources. When multiple inputs are available to the BatteryPlus35-II, the BatteryPlus35-II uses power as specified in the tables below to provide the current to simultaneously power caravan loads and charge the caravan battery.
Auxiliary WARNING To prevent your car battery from discharging when the vehicle’s ignition is off, please ensure the auxiliary is wired so that it is automatically disconnected in this condition The auxiliary input is designed for use with 12V DC power sources. The voltage of the DC power source connected to the auxiliary input must not exceed 14.8V. Fuse protection is required at the auxiliary’s positive input and to protect the wiring from the source.
BATTERY CHARGING AND MANAGEMENT WITH THE BATTERYPLUS35-II WARNING Do not attempt to charge non-rechargeable batteries. Charging a nonrechargeable battery may result in the battery catching fire or possible explosion. The BatteryPlus35-II can deliver up to 35A to simultaneously power loads and charge the caravan battery, with a maximum charging current of 20A for the BP35-II-SI and BP35-II-SR and 30A for the BP35-II-HA with the difference being reserved to supply 12 V loads.
Battery Health Preservation The BatteryPlus35-II preserves battery health by preventing the battery from excessive discharge. The BatteryPlus35-II will start a two-stage shutdown or Low Voltage Disconnect (LVD), powering down the BatteryPlus35-II outputs. This is to conserve remaining battery capacity until the battery can be charged. LVD MODE LEAD ACID LIFEPO4 (HA ONLY) ECO 10.5V 12.0V Storage 9.8V 11.5V Recovery 12.8V 13.
Heavily Discharged Batteries (Lead Acid) The BatteryPlus35-II is will not charge heavily discharged lead acid batteries. In normal use, and with the BatteryPlus35-II battery health preservation, batteries should never become heavily discharged. If your battery is heavily discharged, disconnect if from the BatteryPlus35-II and charge with a stand-alone charger. Reconnect the battery once the battery voltage has recovered to normal levels.
Over-Temperature, Over-Voltage and Short Circuit Overload Protection The BatteryPlus35-II provides automatic protection for over-temperature, overvoltage and short circuit overload situations. If any of these situations are detected, the BatteryPlus35-II will shut down and automatically attempt a restart every 30 seconds until the fault is removed. SERVICING, MAINTENANCE AND STORAGE SERVICING This BatteryPlus35-II contains hazardous voltages and energy hazards that may cause death or injury.
FAQS AND TROUBLESHOOTING Need more help troubleshooting your BatteryPlus35-II? Contact our customer service team online at teambmpro.com/technical-support or check out our how-to videos on our YouTube channel at youtube.com/c/bmproau BATTERY I’ve fitted a battery to the BatteryPlus35-II, but it’s not detected by my BMPRO battery monitor? Check the following: 1. Battery connections are tight and not loose or corroded. 2. Battery polarity, red lead-positive, black lead-negative. 3.
None of my loads appear to be powered and the screen on my battery monitor has turned off? All loads, including any battery monitor in use with the BatteryPlus35-II will power down if the BatteryPlus35-II was put into Storage Mode. The BatteryPlus35-II will be put into Storage Mode if: 1. The user activated the switch connected to the BatteryPlus35-II RSW input. This turns off power to all caravan loads and accessories connected to the BatteryPlus35-II CAN bus such as your battery monitor.
APPENDICES BATTERYPLUS35-II OPERATIONAL STATUS INDICATOR Table 6 displays the operational status of the BatteryPlus35-II, as shown by the coloured flash of the LED Status Indicator on the BatteryPlus35-II.
BATTERY CHARGING MANAGEMENT ALGORITHM The following describes the Battery Charging Management Algorithm used by the BatteryPlus35-II when charging the caravan battery from a mains power source and by the BatteryPlus35-II-HA and BatteryPlus35-II-SR with solar charging. The BatteryPlus35-II will operate as described when the caravan loads are connected directly to the BatteryPlus35-II and not the caravan battery.
