DC-DC Charger MiniBoost
Installation with BP35HA
In-vehicle 12V DC-DC charger for your RV
BMPRO’s Miniboost DC-DC charger is a critical component of complete BMPRO Power Management solutions and is capable of charging Lithium batteries in conjunction with a BP35HA, J35 or ASPERO with integrated solar capability.
MiniBoost is a compact DC-DC charger /booster for RVs. It is specially designed to work with BMPRO’s BatteryPlus35, J35 & ASPERO systems. Charge your caravan or camper trailer’s house battery from the towing vehicle’s electrical system, even if the voltage delivered from the tow vehicle is lower than required for a recharge.
Need more power for charging whilst driving? Refer to the MiniBoostPRO 30Amp DC-DC charger. Compatible with all battery chemistries and includes the power of solar.
The MiniBoost is not a power supply and must be connected to a battery.
To get more out of your solar panels while driving, or to use the DC-DC charger with a lithium battery, refer to 30A DC-DC charger MiniBoostPRO.

(*Lithium LiFePO4 battery when installed with BP35HA inc Solar)
The MiniBoost will not connect directly to a solar panel. Refer to the MiniBoostPRO to use with solar input.
The MiniBoost can be connected directly to the battery but all loads must be fused.
The MiniBoost has four connections. Connect orange to batt+ input, connect white to batt- input, connect red to batt+ (battery to be charged) and black to the batt-.
It can serve on the auxiliary input to other battery management systems or can be directly connected to a battery. The MiniBoost will also work with a Genius and ST series and may also work with with other charging systems.
If the vehicle remains connected, the vehicle battery will be drained, and the secondary battery may be overcharged.
Pending the ventilation and location this may be possible though you need to protect the unit from dust and water ingress. The MiniBoost is not waterproof and has a thermal cut out at 50°C.
The protection is designed to protect the wiring.
The MiniBoost can be connected to the auxiliary input of the BP35, J35 or ASPERO. Initially when connected, the MiniBoost will provide a low current output until it detects a valid battery connected to the BP/J35/ASPERO. If the battery is not detected, the MiniBoost will shut down.
It is recommended to have a suitably qualified person wire in the relay into your car and the MiniBoost as close as possible to the house battery to ensure optimal performance
