The Yinlong 2.3V 40Ah Lithium Titanate (LTO) Battery, model LTO66160, excels in low-temperature performance, rapid 10C discharge, and long lifespan. Designed for DIY 12V/24V systems, its lithium titanate chemistry ensures stability, safety, and efficiency in extreme conditions. EVE Battery’s collaboration enhances its reliability for renewable energy, EVs, and industrial applications.
How Does Lithium Titanate Chemistry Improve Battery Performance?
Lithium titanate (LTO) batteries replace graphite anodes with titanate nanostructures, enabling faster ion transfer. This reduces internal resistance, supports 10C continuous discharge, and operates in temperatures as low as -30°C. Unlike LiFePO4, LTO batteries endure 20,000+ cycles with minimal degradation, making them ideal for high-demand applications like electric vehicles and grid storage.
The unique spinel crystal structure of lithium titanate allows three-dimensional lithium-ion diffusion, achieving charge times under 10 minutes without lithium plating. This chemistry also eliminates SEI layer formation – a major cause of capacity fade in conventional lithium-ion batteries. In hybrid vehicle testing, LTO cells maintain 95% capacity after 15,000 deep cycles compared to 70% retention in NMC counterparts. The anode’s high lithium insertion potential (1.55V vs Li+/Li) prevents dendritic growth, enabling safe operation at 100% depth of discharge.

Why Choose Yinlong LTO for DIY 12V/24V Battery Systems?
Series configurations of 6 cells create 13.8V (12V system) or 12 cells for 27.6V (24V system). Yinlong’s low internal resistance (0.3mΩ) prevents voltage drop under load. DIY builders benefit from no BMS requirements due to inherent overcharge resistance. Example: 24V 200Ah setup uses 12 cells, delivering 4.8kWh with 95% efficiency in solar setups.
Differences Between Eve and Other Brands
When configuring 48V systems, 21 cells in series provide 48.3V nominal voltage with ±2% voltage tolerance across cells. Parallel connections scale capacity linearly – four 40Ah cells yield 160Ah while maintaining 10C discharge capability. The battery’s flat discharge curve (2.25V-2.35V under load) simplifies voltage regulation, requiring only basic DC-DC converters for 12V appliance compatibility. Field tests show 98.7% energy retention in 24V configurations after 500 charge cycles at 1C rate.
What Safety Features Does the Yinlong LTO Battery Include?
The LTO66160’s zero-strain crystal structure eliminates thermal runaway risks. Third-party nail penetration tests show maximum temperature of 85°C vs. 600°C in NMC batteries. Built-in CID (Current Interrupt Device) activates at 150kPa internal pressure, achieving UL1642 certification. Electrolyte additives reduce gas generation by 90%, enabling safe use in confined spaces.
Advanced safety mechanisms include dual-stage pressure relief vents and ceramic separators rated for 800°C thermal stability. The battery management system (optional) monitors cell voltage within ±10mV accuracy and disconnects at 2.8V overcharge threshold. In abuse testing, over-discharge to 0V causes no permanent damage – cells recover 99.3% capacity after recharge. Fire resistance tests meet UN38.3 standards with zero flame propagation during external short-circuit scenarios.
“Yinlong’s LTO tech redefines extreme-condition energy storage. Our tests show 88% capacity at -30°C after 2,000 cycles – a 600% improvement over LiFePO4. The 10C rate enables 6-minute fast-charging for e-scooters, pushing the boundaries of battery physics.” – Dr. Chen, EV Battery Research Institute
- Can Yinlong LTO Batteries Replace Lead-Acid in Cars?
- Yes. A 40Ah LTO battery weighs 1.8kg vs 12kg for equivalent lead-acid, with 10x faster recharge. Cold-cranking amps reach 800A at -30°C, outperforming AGM batteries by 300%.
- How to Store Yinlong LTO Batteries Long-Term?
- Store at 30-50% SOC in temperatures below 45°C. LTO self-discharge is 2%/month vs 5% for Li-ion. No periodic charging needed for up to 3 years – capacity recovery remains above 99%.
- Are LTO Batteries Worth the Higher Cost?
- With 25-year lifecycle in solar applications (vs 8 years for LiFePO4), LTO’s $0.03/cycle cost beats Li-ion’s $0.12/cycle. Break-even occurs at 1,200 cycles, making it economical for daily-use systems.
