EVE LF50K (50Ah): Built for Power

The EVE LF50K is not your average storage battery. It is a premium High-Rate Discharge LiFePO4 prismatic cell designed specifically for applications that demand raw power. While standard 50Ah cells struggle above 50A, the LF50K comfortably delivers 150A continuous and surges up to 250A.

Why Choose LF50K Over Standard Cells?

Unrivaled Discharge Rate: With a 3C Continuous (150A) rating, a 4S (12V) pack can deliver nearly 2000W of continuous power. This is game-changing for small electric vehicles and high-power inverters.
Instant Acceleration: The 5C Pulse (250A) capability ensures that electric motors get the immediate torque needed for acceleration, without the voltage sag seen in lesser batteries.
Low Internal Resistance: With an impedance of ≤0.7mΩ, the cell runs cooler under heavy load compared to standard ESS cells, extending the battery’s lifespan even in demanding conditions.

Why Buy from DLCPO?

Genuine EVE Power: We source authentic LF50K cells directly. Beware of re-wrapped storage cells sold as “high power”—only the real LF50K can handle these currents safely.
Matched for Performance: High-power packs require perfect balance. We test and match every cell to ensure they charge and discharge in unison.
DDP Shipping: We ship these dangerous goods (High Power Class 9) safely to your door in Brazil, Europe, and the USA, handling all customs formalities.

❓ Q:❓Q: Can I use this for solar storage?

💡 A:

A: Yes, you can. It will work perfectly and last a long time, but it is “overkill” for solar. Its premium price reflects its high-power capabilities.

❓ Q:❓Q: What busbars should I use?

💡 A:

A: Because this cell can output 150A+, you must use thick copper busbars (at least 20mm x 3mm copper or braided straps) and high-quality connections. Standard thin strips will melt.

❓ Q:❓Q: Is this suitable for a car starter battery?

💡 A:

A: Yes. A 4S pack of LF50K provides enough cranking amps (250A+) to start many 4-cylinder and V6 engines easily.

Warnings & Cautions

1. Do not immerse the battery in water and keep it dry when not using；
2. Do not strike, throw or subject the battery near a fire or in extremely hot conditions；
3. Charge with specified charge according to charging requirement；
4. Do not reverse the positive (+) and negative (-) terminals；
5. Do not put the battery into a fire or apply direct heat to it；
6. Do not short-circuit the battery by connecting wires or other metal objects to the positive (+) and negative (-) terminals；
7. Do not ship or store the battery metal objects, such as necklaces, hairpins, etc；
8. Do not knock, throw, tread, bend, etc；
9. Do not directly solder the battery terminals；
10. Do not pierce the battery casing with a nail or other sharp object.
11.Notice: This is a high-power cell. Ensure your BMS and wiring can handle 150A continuous / 250A peak current to avoid overheating.
