FAQs of 48V Light Electric Vehicle Lithium Battery

  • ​Why is the nominal voltage 51.2V instead of 48V?

    The LSV battery uses LiFePO4 cells (3.2V each), with 16 cells in series: 16 × 3.2V = 51.2V (nominal voltage). This provides a stable, efficient power supply slightly higher than 48V, enhancing performance for consistent speed and range.

  • How do I choose the right capacity (230Ah–340Ah) for my vehicle?

    Select based on your daily usage:

    230Ah: Suitable for short routes or light loads (e.g., hotel shuttles with frequent stops).

    340Ah: Ideal for extended tours or heavy-duty use (e.g., hilly terrain, full-capacity passenger transport).

    Pro Tip: Match or slightly exceed your original lead-acid battery capacity (convert using LiFePO4’s 75% efficiency ratio if replacing lead-acid).

  • Can I use this battery with my existing 48V lead-acid charger or controller?

    No. Lithium batteries require a LiFePO4-compatible charger (54.4V constant voltage, 0.2C charging current). For controllers, ensure they support 51.2V nominal voltage and your vehicle’s peak power demands to avoid damage.

  • What is the lifespan and cycle life of this battery?

    Designed for 4,000+ charge cycles (80% DOD) and a 10+ year design life with proper use. This is 10x longer than lead-acid batteries, reducing replacement costs and downtime.

  • Is it safe to install in my vehicle? Does it require maintenance?

    Yes—LiFePO4 chemistry is inherently stable, with low risk of thermal runaway and no toxic emissions. It’s zero-maintenance (no watering, equalizing, or periodic full discharges needed). Just ensure proper wiring and ventilation.

  • How much weight does it save compared to lead-acid?

    Up to 50% lighter than equivalent lead-acid batteries. The lightweight design improves vehicle efficiency, acceleration, and handling while reducing energy consumption.

  • How long does it take to charge, and can I charge it partially?

    Full Charge: 4–6 hours with a compatible charger (0.2C rate).

    Partial Charging: Safe and recommended—LiFePO4 has no “memory effect,” so you can charge it at any state of charge without performance loss.

  • Does it come with a warranty? What’s covered?

    Yes—we offer a 5-year warranty covering manufacturing defects and capacity retention (≥80% of rated capacity). Contact us for installation support and troubleshooting.
