Why Choose Roy Power Batteries Instead Of Conventional Lead Acid Batteries?
Roy Power lithium batteries outperform lead acid in energy density (3x higher) and cycle life (2000+ vs 500 cycles). They maintain 95% capacity after 1500 cycles with zero maintenance, while lead acid degrades to 50% capacity within 18 months.
What energy efficiency differences exist between the technologies?
Roy Power cells achieve 99% charge efficiency versus lead acid’s 70-85%. Deep discharges below 20% SOC permanently damage lead acid plates, while lithium safely discharges to 0% without sulfation.
Lithium-ion chemistry enables rapid 1C charging (0-100% in 1 hour) versus lead acid’s maximum safe rate of 0.3C. A 100Ah Roy Power battery delivers 105Ah usable capacity at -20°C, compared to lead acid’s 40Ah with 50% voltage sag. Unlike flooded lead acid, there’s no electrolyte stratification requiring equalization charges.
How do lifecycle costs compare over 10 years?
Initial $1000 lithium investment saves $3800 versus $4800 lead acid replacements. Includes zero watering labor and 50% reduced charging costs from higher efficiency.
| Cost Factor | Roy Power | Lead Acid |
|---|---|---|
| 10-Year Replacement Cycles | 0 | 4 |
| Maintenance Hours | 0 | 120+ |
Partial state-of-charge operation common in solar applications degrades lead acid 3x faster. Lithium tolerates 8000+ partial cycles versus 1200 for AGM batteries.

FAQs
Most 12V/24V/48V systems support direct replacement using voltage-compatible BMS. Disable lead acid-specific charging profiles first.
Do lithium batteries require temperature-controlled storage?
Operate from -20°C to 60°C without performance loss. Lead acid capacity drops 40% below 0°C and risks freezing damage below -10°C.
