Questions and answers

Is this a charger or a battery?
It is a charger. The 25Ah figure describes the lithium battery capacity it is designed to charge, and it outputs 12V.
Can it charge a lead-acid or AGM battery?
No. It is listed for 12V lithium batteries only, and lithium charge profiles differ from lead-acid ones.
Can it stay mounted on the boat?
Yes. It is an on-board charger with an IP68 water and dust rating, so it is built to stay wired in place in a wet compartment.
What happens if I connect it backwards?
It has reverse connection protection, which is meant to prevent damage from a reversed hookup. Check polarity anyway before connecting.
How long does a full charge take?
The charge current is not listed, so charge time cannot be calculated. A 25Ah pack needs roughly 25A for about an hour at a 1C rate, and longer at lower current.
What is in the box?
The listing does not detail box contents. Confirm that mounting hardware and cabling are included before you buy.
