1. How long does the 25.6V 200Ah battery last?
Typically 10–15 years with 4000–6000+ cycles (80% DoD), depending on usage, depth of discharge, and temperature conditions.
2. What is the actual capacity in watt-hours (Wh)?
5120Wh (25.6V × 200Ah = 5120Wh).
3. How long does it take to charge?
Charging time depends on the charger current. With a 100A charger, about 2 hours from empty to full. Recommended charge current is typically 50–100A.
4. Can it be used in cold weather?
Yes, discharge down to -20°C is supported. Many models feature self-heating to enable charging in sub-zero temperatures.
5. Can I connect multiple batteries in series or parallel?
Yes. Most models support parallel connection (up to 16 units) to increase capacity. Series connection is also supported to achieve higher system voltages (e.g., 48V), though some models restrict series connection.
6. Does it require a separate BMS?
No, an integrated smart BMS is built into the battery, providing comprehensive protection and cell balancing.
7. Can this battery replace my existing lead-acid battery?
Yes, it is designed as a drop-in replacement for 24V lead-acid battery banks, offering lighter weight, longer life, and higher usable capacity.
8. What is the recommended storage condition?
Store in a clean, dry, ventilated area at 15–25°C. For long-term storage, maintain at approximately 60% SOC and recharge every 3–6 months.
9. What applications is this battery suitable for?
Solar energy storage, RVs, marine vessels, golf carts, UPS systems, off-grid homes, electric vehicles, and industrial backup power.
