Cycle Life & Depth of Discharge | Get the Most from Your LiFePO₄ Battery

When choosing a LiFePO₄ battery, most people focus on capacity—but how you use your battery determines how long it will last.
Two key concepts you should understand:
✅ Cycle Life
✅ Depth of Discharge (DoD)

🔁 What is Cycle Life?

A cycle means one full charge + one full discharge.
For example, if you run your 100Ah battery down to 20% and then recharge it to 100%, that counts as one cycle at 80% DoD.

SOK and RUiXU batteries typically offer:

• 🔋 4000–6000+ cycles at 80% DoD
• 💡 That’s 10+ years of use for most off-grid or mobile setups

The fewer cycles a battery can handle, the sooner it will need to be replaced.

📉 What is Depth of Discharge (DoD)?

DoD is how much of the battery’s capacity you actually use per cycle.

The deeper you discharge your battery each time, the fewer total cycles it will last.

🧠 Why This Matters

Choosing a battery with more cycles and managing DoD properly means:

• ✅ You replace batteries less often
• ✅ You get better long-term value
• ✅ Your solar or RV system stays reliable for years without interruption

For example:

A cheap lithium battery rated for 2000 cycles may only last 5 years.
A SOK battery with 6000 cycles at 80% DoD can last over 12–15 years in a solar setup.

💡 Pro Tip: Use a Battery Monitor

Install a monitor or Bluetooth app (included with most SOK batteries) to track usage and avoid over-draining your battery.
