The WNRLN MR-12100-LFP 12V 100Ah LiFePO4 Marine Battery delivers 90Ah of usable energy — 80% more runtime for your trolling motor, fish finder, and onboard electronics.
| Scenario | Why MR-12100-LFP |
|---|---|
| Trolling Motor | 90Ah usable = 6-8 hours continuous trolling at medium speed — 80% longer than lead-acid |
| Sailboat House Bank | Powers navigation, lighting, refrigeration, autopilot — decades of liveaboard service |
| Bass Boat Electronics | Stable 12.8V keeps fish finders, GPS, livewell pumps running all day without voltage sag |
| Marine Auxiliary | Dedicated power for windlass, bow thruster, dinghy motor — saves 20 kg vs lead-acid |

Q: How is 90% usable different from lead-acid?
A: A 100Ah lead-acid battery can only be discharged to 50% (50Ah usable) before voltage drops below 11.5V. The MR-12100-LFP delivers 90Ah usable — effectively 80% more runtime from the same Ah rating.
Q: Can I use this with my existing marine charger?
A: We recommend a 12V 20A LiFePO4 smart charger. Standard lead-acid chargers with desulfation modes can damage lithium cells. Charger add-on: USD 65 with bulk orders.
Q: Warranty?
A: 3-year standard. CE, UN38.3, MSDS certified. ABYC compliant design.
