USING YOUR BATTERYPLUS35
INPUT POWER SOURCES
The BatteryPlus35 may be powered from auxiliary, mains and solar input sources.
When multiple inputs are available to the BatteryPlus35, the BatteryPlus35 uses
power as specified in the tables below to provide the current to simultaneously
power caravan loads and charge the caravan battery.
Table 4: Input Power Sources to the BP35-PM
INPUT SOURCE TO BatteryPlus35 POWER SOURCE
AUX + Mains Mains
AUX + Solar AUX/Solar Blending
AUX + Mains + Solar Mains/Solar Blending
Mains + Solar Mains/Solar Blending
Table 5: Input Power Sources to the BP35-HA and BP35-SR
INPUT SOURCE to BatteryPlus35 POWER SOURCE
AUX + Mains Mains
AUX + Solar AUX/Solar Blending
AUX + Mains + Solar Mains
Mains + Solar Mains
Auxiliary
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 positive input. The rating on this
protective fuse must not exceed 30A
Mains
The BatteryPlus35 mains power cord can accept power from either a 110V or 240V
voltage outlet.
To prevent your car battery from discharging when the vehicle’s ignition is off, please
disconnect the auxiliary input to the BatteryPlus35 whenever the car is not running.

12
Solar Input on the BP35-PM
Connection of solar panels to the BP35-PM must always be through an external
regulator. The external regulator may either be a Maximum Power Point Tracker
(MPPT) regulator or Pulse Width Modulator controller.
Always consult with manufacturer’s specifications before choosing an external
regulator to fit between your solar panels and the BP35-PM, ensuring that:
1. The solar regulator output does not exceed 30A, and
2. The charging profile of the solar regulator is suitable for the battery in use
Solar Input on the BP35-HA and the BP5-SR
The BP35-HA and the BP35-SR both feature an in-built MPPT charger. This
enables solar panels to be connected directly to the BP35-HA or BP35-SR without
the need for an external regulator.
The MPPT charger supports the use of standard 12V solar panels up to a total of
450W.
DO NOT connect solar panels directly to the BP35-PM solar input terminals.
BATTERY CHARGING AND MANAGEMENT WITH THE BATTERYPLUS35
The BatteryPlus35 can deliver up to 35A to simultaneously power loads and
charge the caravan battery, with a maximum charging current of 20A for the
BP35-PM and BP35-SR and 30A for the BP35-HA.
The maximum charging current will be reduced if the loads present are drawing
significant current and as the battery approaches full charge. To ensure that the
caravan battery is charged by the maximum charging current, switch off non-
essential loads.
Auxiliary Charging
When charging from auxiliary, the BatteryPlus35 monitors the battery voltage
level and charges as needed. Auxiliary charging is enabled only when the auxiliary
voltage exceeds the battery voltage by at least 0.5V.
Mains Charging
When charging the battery from mains, the BatteryPlus35 applies a multi-stage
charging algorithm. Further details can be found in the Appendices.
Solar Charging with the BP35-PM
Battery charging depends on the solar regulator used to connect the solar panels
to the BP35-PM.

13
Solar Charging with the BP35-HA and BP35-SR
When charging the battery from solar, the BP35-HA and BP35-SR applies a multi-
stage charging algorithm.
The BatteryPlus35 (HA and SR) will use solar as a charging source is the voltage
generated by the solar panel is greater than 17.5V for at least two minutes.
Battery Health Preservation
The BatteryPlus35 preserves battery health by preventing the battery from
excessive discharge. The BatteryPlus35 will start a two-stage shutdown or Low
Voltage Disconnect (LVD), powering down the BatteryPlus35 outputs. This is to
conserve remaining battery capacity until the battery can be charged.
LVD MODE LEAD ACID LiFePO4 (BP35-HA ONLY)
ECO Mode 10.5V 12.0V
Storage Mode 9.8V 11.5V
Recovery 12.8V 13.8V
Table 5: LVD Mode voltage thresholds
The BatteryPlus35 will enter the two stages of LVD, ECO Mode and Storage Mode,
when the caravan’s battery voltage falls below the LVD thresholds.
ECO MODE
The BatteryPlus35 will provide power to the CAN bus. This allows you to continue
to monitor battery consumption from your battery monitor. However, power to the
load terminal block will be turned off (except for terminal 1) and you will not be
able to use your battery monitor to power caravan loads.
To exit ECO Mode, start battery charging. The BatteryPlus35 will exit ECO Mode
when the battery charges to the Recovery voltage. Upon exit of ECO Mode, the
BatteryPlus35 will automatically return to its previous state of operation.
When in ECO Mode you may temporarily turn on caravan loads for a short time by
cycling the switch connected the BatteryPlus35’s RSW input. This feature allows
you to retract slide-outs or electric steps should you need to pack your caravan.
If a battery monitor is connected, this may also be done by pressing the Battery
button.

14
STORAGE MODE
Power to load output terminal 1 and the CAN bus will now be turned off; meaning
no communication or power to the accessories connected to the BatteryPlus35
CAN bus.
To exit Storage Mode, start battery charging. The BatteryPlus35 will exit Storage
Mode when the battery charges to the Recovery voltage.
When in Storage Mode you may temporarily turn on caravan loads for a short time
by cycling the switch connected the BatteryPlus35’s RSW input.
Heavily Discharged Batteries (Lead Acid)
The BatteryPlus35 will not charge heavily discharged lead acid batteries.
In normal use, and with the BatteryPlus35 battery health preservation, batteries
should never become heavily discharged.
If your battery is heavily discharged, disconnect it from the BatteryPlus35 and
charge with a stand-alone charger. Reconnect the battery once the battery
voltage has recovered to normal levels.
Heavily Discharged Batteries (LiFePO4) (BP35 Model HA only)
The BP35-HA 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 BP35-HA will provide the
voltage to restart the LiFePO4 battery’s BMS and then commence charging of the
LiFePO4 battery.

15
USING THE BATTERYPLUS35 AS A POWER SUPPLY (BATTERY-LESS
OPERATION)
The BatteryPlus35 will act as a power supply if the following conditions are met:
1. A battery is not connected to the BatteryPlus35, and
2. The BatteryPlus35 is configured to charge Lead Acid batteries, and
3. The BatteryPlus35 is connected and powered from mains, or
4. The BatteryPlus35 is connected and powered from AUX input
Power Supply mode allows you to control and power your caravan’s loads directly
from mains or AUX without the need to connect the caravan battery. When
powered from the mains, the BatteryPlus35 provides an output voltage of 12.8V.
When powered from an AUX input, the output voltage will vary depending on the
AUX input voltage.
This mode of operation is unavailable with a solar power source.
FAULT PROTECTION
Electronic Load Fuse Protection
Each load output is protected by an internal electronic fuse. Electronic fuses are
auto-recoverable and eliminate the need for the user to replace a blown fuse.
The electronic fuse will act if the BatteryPlus35 detects a current greater than
the current rating of the terminal and the corresponding LED in the Load Output
Status Indicator on the BatteryPlus35 will flash red.
The LED indicators have a narrow viewing window. To view the LED colour
clearly, one must be directly above the LED indicators.
The BatteryPlus35 will power off the faulty load and resume normal operation
once the fault has been rectified.
Over-Temperature, Over-Voltage and Short Circuit Overload Protection
The BatteryPlus35 provides automatic protection for over-temperature, over-
voltage and short circuit overload situations.
If any of these situations are detected, the BatteryPlus35 will shut down and
automatically attempt a restart every 30 seconds until the fault is removed.

16
SERVICING
The BatteryPlus35 contains hazardous voltages and energy hazards that
may cause death or injury. Only qualified service personnel may service the
BatteryPlus35. Do not attempt to service the BatteryPlus35 yourself, OR
dismantle, modify or repair the BatteryPlus35 yourself; this will void your
warranty.
If your BatteryPlus35 requires servicing other than what is stated in this Owner’s
Manual, please consult your BMPRO dealer.
MAINTENANCE
Use a dry or moist cotton cloth to lightly remove dust or dirt from the
BatteryPlus35. Do not use alcohol, thinners, benzene or any other chemical
cleaner as these products may degrade the housing surface. Do not allow any
liquids to enter the housing.
Be sure to turn off all power sources to the BatteryPlus35 and disconnect the
battery before cleaning.
STORAGE
Once your adventure is over be sure to charge the caravan’s battery and power off
loads. Use the switch connected to the BatteryPlus35 RSW input to enter Storage
Mode and power off all loads.
When not in use, it is recommended that you recharge the caravan’s battery,
ideally monthly, or every three to six months. Regular recharge prevents the
battery from becoming heavily discharged-a condition which can significantly
shorten the battery’s lifespan.

FAQS AND TROUBLESHOOTING
Need more help troubleshooting your BatteryPlus35? Contact our customer
service team online at teambmpro.com/technical-support or give us
a call on [phone].
BATTERY
I’ve fitted a battery to the BatteryPlus35, 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. The dealership fitted in-line fuse with the caravan battery is fitted and not
blown. Correct value is 40A.
CARAVAN LOADS
I think one of my loads is not receiving power?
The load may be faulty, activating the protective electronic fuse and turning the
load off. If this is the case, the Load Status Indicator LED for that load will be red.
Should you encounter any faulty loads, please contact your caravan dealership.
None of my loads appear to be powered but I can still use my battery monitor?
All loads will power down, but the battery monitor will still be in use if the
BatteryPlus35 was put into ECO Mode. The BatteryPlus35 will be put into ECO
Mode if:
1. The user pressed the Battery icon on their battery monitor.
Check to see that Battery icon on your monitor has been pressed, thus turning
power off to the caravan loads.
2. The BatteryPlus35 has entered ECO Mode and to conserve remaining battery
voltage will disable power to caravan loads.
Connect the BatteryPlus35 to a power source and begin battery charging.

18
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 will power
down if the BatteryPlus35 was put into Storage Mode. The BatteryPlus35 will be
put into Storage Mode if:
1. The user activated the switch connected to the BatteryPlus35 RSW input.
This turns off power to all caravan loads and accessories connected to the
BatteryPlus35 CAN bus such as your battery monitor.
Check that the switch has not been activated.
2. The BatteryPlus35 has entered Storage Mode and to conserve remaining
battery voltage will disable power to all caravan loads and accessories
connected to the BatteryPlus35 CAN bus.
Connect the BatteryPlus35 to a power source and begin battery charging.
SOLAR
Solar Output Appears to be Lower than Expected
If the battery is close to fully charged, the BatteryPlus35 will periodically turn
off solar to protect the batteries from overcharging. As a result, you may see less
output on your solar display.
The following tips will also make sure you are getting the most of your solar set-
up:
1. Make sure your solar panels are clean
For optimal performance of your solar panels, regularly clean them (when
cool) with warm, soapy water.
2. Consider the location of your caravan/RV
A shadow (for example from trees, buildings and even other accessories on
the roof of your caravan) across any part of the solar panel can reduce the
panel performance by up to 80%.
3. The time of day and time of year is important as well.
In some parts of the year (especially is southern parts of Australia) the sun will
never be directly overhead, so your solar output will be reduced-sometimes by
up to 50%.
