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.

FAQs
Yes, the ProBoost40 will work with smart alternators.
We recommend using bolt down fuses, as they ensure a low resistance connection.
Blade type fuses are not recommended. These fuses can result in a high resistance connection which causes excess heat, which may damage the fuse holder and/or the wiring.
Self-resetting circuit breakers are not recommended. These may trip prematurely due to the heat generated by the current flowing through the wires.
The ProBoost is designed to work as a standalone product for charging the auxiliary battery in the tow vehicle.
If you want 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.

While I am yet to really put this to the test I am sure it will be as other BMPro products that I have. Good range of products and excellent customer service. Would recommend.
I have installed this Pro-Boost 40 to my 2 x 110AH lithium batteries with 600W of solar, and this system boosts charging capability for my off-grid setup in my caravan. Great product and works efficiently and quickly charges back from 60% up to 100% while totally off grid relying on Solar only to charge up.
