Deep Cycle Lithium Battery for Marine and RV Use
Deep Cycle Lithium Battery for Marine and RV
A deep cycle lithium battery is built for repeated deep discharge – exactly what marine and RV house banks need. LFP is the default for its safety and 2,000-5,000 cycle life.
Why Lithium Over Lead-Acid
| Factor | LFP | Lead-acid |
|---|---|---|
| Usable DoD | 80-90% | 50% |
| Weight | 1/3 | Heavy |
| Cycles | 2,000-5,000 | 300-500 |
Use Tips
- Use IP67 or enclosed modules in wet environments.
- Size to daily Ah draw at 80% DoD.
- Pick a lithium battery manufacturer with marine-grade builds.

Frequently Asked Questions
Can I replace my AGM directly?
Often yes, but upgrade the charger to a lithium profile and check alternator charging.
How long will it last?
Typical LFP banks deliver 8-12 years of seasonal use.
