Intelligent DC-DC chargers

BMPRO’s ProBoost40 is a DC-DC battery charger that allows you to charge a secondary battery using solar panels and/or a towing vehicle’s 12V electrical system.

The ProBoost40 utilises solar and auxiliary inputs to produce a maximum of 40A which ensures there is a consistent charge to your battery.

Compatible with both lead-acid and lithium LiFePO4 batteries, the high power density design of the ProBoost40 provides efficiency of up to 95%.

The ProBoost40 has an ultra-thin design, making it suitable for installation in small spaces, and is resilient to shaking, as well as wet, dusty or muddy environments.

A range of protective features built into the ProBoost40, such as overtemperature, overvoltage and undervoltage protection, will guard your charging capacity.

Key Features
- Dual input MPPT solar/aux (alternator)
- Multi-battery chemistry selector
- IP56 rating – resistant to dust, water & shock damage
- Maintains a 100% state of charge of auxiliary batteries
- Suitable for under-bonnet installation

*The ProBoost is designed to work as a standalone product.

To use this with a BMPRO Power Management System, such as the BatteryPlus35-II or the J35, you will need to connect it through a BC300 External Shunt.
