Types of Lithium-Ion Batteries: LiFePO4 vs. NMC
When powering fishing electronics—whether on the ice or open water—many anglers turn to lithium-ion batteries for their lighter weight, longer run times, faster charging, and multi-season reliability. Within lithium, there are two primary chemistries to know: LiFePO4 (Lithium Iron Phosphate) and NMC (Nickel Manganese Cobalt). Our Fishing Experts break down what sets them apart so you can choose the right battery for your setup.
About LiFePO4 Lithium-Ion Batteries
LiFePO4 batteries are built for longevity and safety, making them a favorite among anglers who want dependable gear season after season.
Advantages of LiFePO4
-
Long cycle life: 2,000–6,000 deep discharge cycles
-
Inherently safe and stable chemistry
-
Still much lighter than sealed lead acid batteries
-
Reliable long-term investment
Disadvantages of LiFePO4
-
Retains less capacity in extreme cold (50–60%)
-
Slower charging speeds than NMC
-
Slightly heavier than NMC batteries
About NMC Lithium-Ion Batteries
NMC batteries are a top choice for anglers because they are designed for maximum performance and portability.
Advantages of NMC
-
Retains more capacity in cold weather (70–80%)
-
Fast charging for quick turnaround
-
Lightest lithium battery option available
-
Ideal for mobile setups and high-performance needs
Disadvantages of NMC
-
Shorter lifespan: 1,000–2,000 deep discharge cycles
-
Less stable chemistry compared to LiFePO4
LiFePO4 vs. NMC Lithium-Ion Batteries Chart
The chart below highlights the key performance differences between LiFePO4 and NMC to help guide your decision.
| Feature | LiFePO4 | NMC |
|---|---|---|
| Cold Weather Performance | Retains 50-60% capacity | Retains 70-80% capacity |
| Lifespan | 2,000-6,000 deep discharge cycles | 1,000-2,000 deep discharge cycles |
| Weight | Heavier than NMC batteries but significantly lighter than SLA | Lightest battery type |
| Charging Speed | Slower than NMC batteries | Faster charging |
| Ideal For | Long term value, safety, and reliability | Highest performance needs |
When choosing a lithium-ion battery from brands like Amped Outdoors or Norsk, you know that you’ll be getting a high-quality battery, but understanding the slight differences between LiFePO4 and NMC batteries will help you make the best decision when choosing a battery.
