FAQs
The MiniBoostPRO Lithium DC-DC charger cannot be used inside an engine bay as it is rated to IP20.
No, as this is due to the MiniBoostPro’s housing being physically and electrically connected to the negative terminal. Always be cautious of accidental connections from the housing to the battery positive terminal.
The MiniBoostPRO is capable of charging multiple batteries installed in parallel.

2 things should be made very clear with this product.
If you have a BMS already you should NOT get the pro because you can’t connect your solar to it anyway.
You need to run the car for 15minutes before it will start charging. This is annoying if you need to boost the battery with the car while at the campground
The device arrived very quickly by post. Very easy to install via the easy to follow instructions. Keeps the battery charged by the car or solar. Great product. Highly recommended
Relatively simple to install onto our existing BMPro battery management system. We needed this unit to up the voltage from our tow vehicle as the aux input on the battery management unit so we could get a full charge on our Lithium battery while towing. I did have some technical issues with the unit but the team at BMPro again were absolutely brilliant in assisting me to resolve these. The only reason this doesn’t get a 5 star from me is that I think the manual could be better. Maybe as a technical writer used to producing these publications I am a little fussy but I do think some better integration information would be really useful. Big tick from me
Perfect – allows much more flexibility when free camping, now we are getting charge to the house batteries off the motor.
Excellent product
Prompt service
Charging at 20-21 amps now rather than < 10 on a sprinter
