48V 20Ah Sodium-Ion Battery – Reliable Power for E-Bikes, Solar Storage & Light EVs

The 48V20Ah sodium-ion battery offers exceptional safety, long cycle life, and stable performance across a wide temperature range. Unlike lithium-ion, it uses abundant, low-cost materials—making it more sustainable and cost-effective. Ideal for energy storage, e-bikes, and light EVs, it delivers reliable power with reduced environmental impact and no risk of thermal runaway.

Q1: What are the key advantages of this 48V 20Ah sodium-ion battery compared to lithium-ion batteries?

A: Our 48V 20Ah sodium-ion battery offers several benefits:

- Enhanced safety: Lower risk of thermal runaway or fire, even under extreme conditions.

- Wider operating temperature range: Performs reliably from -20°C to +60°C.

- Sustainable & cost-effective: Made from abundant sodium resources, reducing reliance on scarce metals like cobalt and lithium.

- Long cycle life: Typically exceeds 3,000 cycles at 80% depth of discharge (DoD).

Q2: What applications is this battery suitable for?

A: This battery is ideal for:

- Electric scooters, e-bikes, and light EVs

- Solar energy storage systems

- UPS (Uninterruptible Power Supply) backup

- Telecom base stations

- Off-grid and residential energy storage

Q3: What is the nominal voltage and capacity?

A: The battery has a nominal voltage of 48V and a rated capacity of 20Ah, delivering 960Wh (48V × 20Ah) of energy.

Q4: Does it include a Battery Management System (BMS)?

A: Yes. Every unit comes with an integrated intelligent BMS that provides:

- Overcharge/over-discharge protection

- Over-current and short-circuit protection

- Cell balancing

- Temperature monitoring

- Communication via CAN or RS485 (optional)

Q5: How long does it take to charge?

A: With a standard 0.5C charger (10A), the battery charges fully in approximately 2–2.5 hours. Fast charging at 1C (20A) is supported for compatible systems, reducing charge time to ~1 hour (subject to thermal conditions).

Q6: Is this battery compatible with existing lithium-ion chargers or inverters?

A: Not directly. Sodium-ion batteries have different voltage profiles (e.g., full charge ~54.4V, cutoff ~36V). We recommend using our dedicated sodium-ion charger or a programmable charger/inverter configured to match sodium-ion specifications. Please consult our technical team for compatibility guidance.

Q7: What is the expected lifespan?

A: Under normal usage (80% DoD, 25°C), the battery retains ≥80% of its original capacity after 3,000+ cycles. Calendar life typically exceeds 8–10 years.

Q8: Is the battery environmentally friendly?

A: Absolutely. Sodium-ion chemistry avoids critical raw materials like lithium, cobalt, and nickel. It’s non-toxic, highly recyclable, and aligns with global sustainability goals.

Q9: What certifications does this battery have?

A: Our 48V 20Ah sodium-ion battery complies with international standards, including UN38.3, CE, RoHS, IEC 62619, and GB/T (Chinese national standards). Additional certifications available upon request.

Q10: Can I get a sample or custom configuration?

A: Yes! We offer sample units for testing and support OEM/ODM services for customized voltage, capacity, casing, or communication protocols. Contact our sales team for details.
