Power Management System for camper trailers & entry level RVers
BMPRO’s ASPERO is a combined battery management system and information display designed for recreational vehicles. The ASPERO powers your loads, charges your battery and provides you with live and easy to understand information about your battery.
The system includes ASPower, a lithium battery-compatible battery management system that operates from 240V AC mains power supply, towing vehicle auxiliary and solar panels to simultaneously power caravan loads and charge the caravan battery.
It employs intelligent charging algorithms, ensuring optimal battery health. Automatic battery preservation mode saves remaining battery power until you’re ready and able to charge.
Also included is the ASDisplay, an information display designed to show you with current information about your battery and connected loads, including the battery level of the connected battery, the charging/discharging state, battery chemistry, active power sources.
To get the most from your ASPERO system it may also be used with the following products (sold separately) from the BMPRO range:
• BC300 + CommLink External Shunt for integration of additional accessories and high current loads such as inverters.
• Dipper water level indicators to monitor the water levels of up to 4 water tanks.

load off. If this is the case, the LED Status Indicator on the ASPower will flash a
Should you encounter any faulty loads, please contact your caravan dealership.
All loads will power down, but the ASDisplay will still be in use if the ASPower
was put into ECO Mode.
The ASPower will be put into ECO Mode if:
The ECO Mode button on the ASDisplay has been pressed.
This turns off power to all caravan loads connected to the ASPower, except output 14.
Check if there is a green LED light next to the ECO Mode button on the
ASDisplay. If there is, press the ECO Mode button again to exit ECO Mode.
Battery voltage is very low. The ASPower will enter ECO Mode to conserve
remaining battery voltage, which will disable power to all caravan loads
connected to the ASPower.
Connect the ASPower to a power source and begin battery charging.
Check the following:
- The battery connections are tight and not loose or corroded.
- Battery polarity: red lead is positive, black lead is negative.
- The battery fuse on the ASDisplay is fitted and not blown. The correct value is 40A.
