WARNING
CAUTION: Risk of fire.
Do not replace any vehicle fuse with a rating higher than recommended by the vehicle
manufacturer.
This product is rated to draw between 20 and 30 amperes from a 12V vehicle outlet, depending on
your model of BatteryPlus35-II. Ensure that the electrical system in your vehicle can supply this
product without causing the vehicle fusing to open. This can be determined by making sure the fuse
in the vehicle which protects the outlet is rated higher than the maximum ampere drawing current
for your BatteryPlus35-II. Information on the vehicle fuse rating are typically found in the vehicle
operator's manual.
If a vehicle fuse opens repeatedly, do not keep on replacing it. The cause of the overload must be
found. On no account should fuses be patched up with tin foil or wire as this may cause serious
damage elsewhere in the electrical circuit or cause fire.

INSTALLATION INSTRUCTIONS
EARTHING
As the BatteryPlus35-II is positive sensing for current monitoring, this allows for
chassis earthing of both the battery and the negative of DC 12V appliances.
Note: All DC 12V positive cables must be wired to outputs 1-14 or the 40A battery
output connection.
Loads Greater Than 15A
For DC 12V appliances that may draw greater than 15A, such as inverters, both
positive and negative must be wired directly to the new battery negative on the
BC300 to ensure the current is seen by the BatteryPlus35-II and the correct
information displayed, such as the State of Charge and Time Remaining.
Refer to our website for more information on this product: https://teambmpro.com/
products/bc300-commlink-external-shunt/
PERSONNEL
Installation is to be carried out only by suitably qualified personnel.
VENTILATION, ORIENTATION AND THERMAL CONSIDERATIONS
The preferred orientation is with the load connection at the bottom and located
so that there is a minimum of 80mm of free air space from all vented sides of the
BatteryPlus35-II. This allows for the lowest operating temperature of the internal
electronics and the highest reliability of the product.
The final enclosure must provide adequate ventilation to the outside world (or larger
internal cavity) to prevent excessive heating of the air within the enclosure.
At normal room temperature (25°C), the unit is rated to provide full power in both
vertical and horizontal orientations. At elevated temperatures of up to 50°C, the
output current is de-rated to 32A.
The BatteryPlus35-II has over-temperature protection and will shut down if
its internal temperature rises above the safe level. The BatteryPlus35-II will
automatically restart once it has cooled to an acceptable level.
WARNING
The enclosure air temperature can easily exceed 50°C if adequate ventilation is not
provided.
WARNING
Do not install the BatteryPlus35-II in a compartment where flammable material is stored,
such as petrol or LPG.
14

MOUNTING
The BatteryPlus35-II should be securely mounted to a suitably rigid surface, using
the four pre-drilled mounting holes.
MAINS CABLE
The BatteryPlus35-II is pre-cabled and fitted with a mains plug. Ensure that the
connections to the mains supply are in accordance with the national wiring rules, and
that the earth connection is installed. For more information, refer to the Mounting
section.
The mains cable must be at least 80mm away from the output cables. For information
on wiring, refer to the Wiring Diagram section.
The plug must be accessible during installation. If this is not possible, an accessible
mains disconnection switch must be incorporated in the mains wiring where the plug
is connected.
WARNING
If the supply cord is damaged, it must not be replaced and the appliance should be
scrapped.
15

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.
The wiring method used with the installation shall be in accordance with National
Electrical Code ANSI/NFPA 70.

After fitting a new battery to the BatteryPlus35-II, make sure that it is configured in
your battery monitor.
Correctly configuring the battery capacity and profile will ensure that the
BatteryPlus35-II will select the best charging parameters for the caravan battery in
use, and the software accurately estimates battery usage.
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.
WARNING
Sparks have the potential to cause an explosion if combustible gases are present.
The following procedures are designed to minimise the risk of spark generation while
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 is stored, such
as petrol.
To protect against short-circuits and reversed battery connections, install a 40A fuse
as close as possible to the battery’s positive terminal.
