Q: 100Ah vs. 200Ah LiFePO4 battery: which is better?

A: There is no absolute "better". It depends on your installation space constraints, budget, and weight sensitivity.
100Ah advantages: High modularity; easily handled by one person (~10-12kg); ideal for tight spaces or flexible expansion (e.g., small RVs, portable power).
200Ah advantages: Higher integration; fewer cables and BMS nodes; a cleaner system with a generally better cost-per-Wh ratio. Ideal for large storage (e.g., home off-grid stations, large vessels).

Q: Can LiFePO4 batteries be charged below 0°C (32°F)?

A: Generally, no. Standard LiFePO4 cells are prohibited from charging below 0°C. Forced charging at low temperatures can cause lithium plating on the negative electrode, forming lithium dendrites. These dendrites can not only cause permanent capacity degradation of the battery, but may also puncture the separator, leading to internal short circuits and thermal runaway.

Q: What is the cycle life of a 12.8V LiFePO₄ battery?

A: At 80% depth of discharge (DOD), the cycle count exceeds 4000. This means over 10 years of service life with one cycle per day, far exceeding the 2 years of lead-acid batteries.

Q: How to upgrade a 12V lead-acid system to LiFePO₄ system?

A: The main steps include selecting a voltage-matched (12.8V) LiFePO₄ battery, verifying compatibility with your existing charging equipment or replacing it with a dedicated lithium charger, ensuring the BMS supports the required current, and checking battery dimensions and cables. After upgrading, you gain lighter weight, longer life (>6000 cycles), and better discharge performance.

Q:Are your factory or trading company?

A:We are professional battery manufacturer with our own factory and brand. We provide all kinds of OEM/ODM services for distributors all around the world.
