Traditional lead-acid batteries (AGM, Gel) only allow you to use around 50% of their capacity. Lithium (LiFePO4) allows 80–90% usable capacity, with consistent voltage under load.
This means:
Lithium batteries accept charge much faster than lead-acid.
Paired with the right system:
For many boat owners, this reduces or eliminates generator use.
The biggest mistake is treating lithium as a “drop-in replacement.”
