ABOUT THE MINIBOOSTPRO
BMPRO’s MiniBoostPRO is a multi-stage DC-to-DC battery charger, that enables
charging a secondary battery from solar panels and / or the towing vehicle’s 12V
electrical system.
Blending both the solar and auxiliary inputs, the MiniBoostPRO provides a
combined maximum charging current of 30A, with a preference to solar for
charging your secondary battery.
When charging, the MiniBoostPRO continually monitors primary, secondary
battery and solar voltage.
COMPATIBLE BATTERY TYPES
The MiniBoostPRO may be used to charge 12V batteries with capacities of 50-
300AH and of the following chemistries: AGM/Wet, Gel and LiFePO4 (lithium).
ADDITIONAL ACCESSORIES REQUIRED FOR INSTALLATION
The following accessories (not supplied) are required to complete installation of
the MiniBoostPRO:
92x 40A Automotive Fuse
92x 2A Automotive Fuse
TERMINOLOGY
Secondary battery refers to either an auxiliary battery installed in the motor
vehicle or a house battery installed in the RV.
Primary battery refers to a cranking battery in the motor vehicle. Connected to
the alternator, it is commonly referred to as an auxiliary input.
Bypass mode is the mode where the primary / input AUX source of power is at
the higher voltage than the secondary / output battery.
Boost mode is the mode where the voltage of the primary battery input source is
less than the secondary / output battery.
WARNING
Do not connect other types of Lithium batteries to the MiniBoostPRO.
Do not connect batteries with capacity less than 50Ah.

INSTALLATION INSTRUCTIONS
Installation of the MiniBoostPRO should be carried out only by a certified
installer with caravan electrical experience.
MOUNTING
Securely mount the MiniBoostPRO to any suitably strong flat surface. Install
the MiniBoostPRO inside your caravan or camper trailer, preferably close to the
house battery.
VENTILATION AND THERMAL CONSIDERATIONS
The MiniBoostPRO may be installed in any orientation. To prevent overheating
of the MiniBoostPRO, install the unit in a well-ventilated area that allows for
continuous airflow around the unit. Overheating of the MiniBoostPRO will affect
the optimal operation of the unit.

WIRING INSTRUCTIONS
WIRING AND CONNECTIONS
To assist with wiring, cable colour codes are labelled on the back of the
MiniBoostPRO. To ensure safe and reliable wiring, wire connections should be
crimped or soldered. All wire connections must be protected by heat shrink to
prevent exposed wires.
The MiniBoostPRO may be used in conjunction with a BMPRO power
management system such as the BatteryPlus35-II or ASPower.
If using a power management system, connect the MiniBoostPRO’s Batt Out
and Common Negative cables to the positive and negative primary input. The
MiniBoostPRO may be wired direct to the secondary battery via a protective
fuse.
CABLE CABLE COLOUR MINIMUM CABLE SIZE
Solar In White 6.0mm or 10 AWG
Aux In Orange 6.0mm or 10 AWG
Batt Out Red 6.0mm or 10 AWG
Common Negative Black 6.0mm or 10 AWG
Ignition Blue 0.34mm or 22 AWG
Batt Chemistry Green 0.34mm or 22 AWG
CABLE SIZE
Cables should be sized to carry 30A. The following table demonstrates the
recommended cable size, ranging up to a total length of 15m from input to
output.
