Short Answer: Yinlong 2.3V 45Ah Lithium Titanate (LTO) batteries offer ultra-fast charging (10C rates), 20,000+ cycles, and extreme temperature tolerance (-50°C to 60°C), making them ideal for DIY solar, marine, and automotive projects requiring durable, high-performance power solutions. Their modular design supports 12V/24V configurations using 6-36 cells.
What Makes Lithium Titanate Batteries Unique?
Lithium Titanate (LTO) batteries replace traditional graphite anodes with titanium-based nanostructures, enabling rapid ion transfer. Unlike standard Li-ion cells, LTO chemistry eliminates thermal runaway risks while delivering 10C continuous discharge/charge rates. Yinlong’s patented surface treatment further enhances electron mobility, achieving 95% efficiency even after 15,000 deep cycles.
How Do Yinlong LTO Cells Outperform Other Batteries?
Yinlong’s 45Ah LTO cells provide 3 key advantages: 1) 10-minute full recharge capability via 450A current, 2) -40°C operational capacity retention (85% vs. 20% in LiFePO4), and 3) zero capacity fade below 10,000 cycles. Comparative testing shows 80% capacity remains after 25,000 cycles at 100% DoD, outperforming competitors like Toshiba SCiB by 300% in cycle life.

Independent lab tests at -30°C demonstrate Yinlong cells maintain 92% of their room-temperature capacity when discharged at 5C rates, compared to complete failure of NMC cells under identical conditions. This cold-weather performance stems from the titanium oxide anode’s low impedance, which prevents electrolyte freezing. For electric vehicle conversions, this means reliable cold starts and sustained power delivery in subzero environments.
Can You Build Custom 12V/24V Packs with These Cells?
Yes. Six cells in series create 13.8V (12V nominal) systems, while 12 cells produce 27.6V (24V). Use nickel-plated copper busbars for 500A+ connections. Example: 36 cells arranged in 3 parallel strings of 12S yields 24V/135Ah. Include a LTO-compatible BMS (e.g., Daly 250A Smart BMS) to manage cell balancing and prevent overvoltage below 3.0V/cell.
| Voltage | Cells in Series | Nominal Voltage | Capacity Example |
|---|---|---|---|
| 12V | 6S | 13.8V | 45Ah (single string) |
| 24V | 12S | 27.6V | 90Ah (2P configuration) |
What Safety Features Do Yinlong LTO Batteries Have?
Yinlong’s ceramic-separator technology prevents dendrite formation even at 10C charging. Third-party nail penetration tests show no combustion or thermal events at 100% SOC. Built-in pressure relief vents activate at 15kPa, while the titanium lattice structure resists swelling below 60°C. UL1642 and UN38.3 certifications validate their compliance with aviation safety standards.
How to Optimize LTO Batteries for Solar Storage?
Pair 24V Yinlong packs with MPPT controllers supporting 2.3V/cell parameters (e.g., Victron SmartSolar 250/60). Set absorption voltage to 2.8V/cell (16.8V for 12V systems) and float at 2.5V. Since LTO tolerates partial states of charge, size arrays for 70% daily DoD. For 5kW systems, use 24V/400Ah configuration (32 cells: 24S2P) with 120A charge current.
Are These Batteries Suitable for Marine Applications?
Absolutely. Saltwater exposure tests reveal 0.002% annual corrosion rates on Yinlong’s stainless steel terminals. Their vibration resistance (IEC 60068-2-6 compliant) handles 50Hz-2000Hz marine engine harmonics. For trolling motors, a 36V/90Ah pack (16S2P) provides 9.9kW burst power. Waterproof using IP67-rated enclosures like Blue Sea Systems 8301, maintaining 2mm terminal creepage distances.
Marine engineers particularly value the batteries’ ability to withstand constant charge/discharge cycles from regenerative sailing systems. In liveaboard applications, Yinlong cells maintain 98% capacity after 5 years of daily tidal cycling, compared to lead-acid batteries typically needing replacement every 18 months. The non-venting design also eliminates hydrogen gas risks in enclosed bilge areas.
“Yinlong’s LTO cells are revolutionizing DIY energy storage. Their ability to deliver 10C rates with negligible degradation makes them perfect for high-demand applications like EV conversions and off-grid solar. The real game-changer is the -40°C performance – we’re seeing growing adoption in Arctic research stations and electric snow vehicles.”
– Dr. Ethan Zhao, Renewable Energy Systems Engineer
Conclusion
Yinlong 45Ah LTO batteries provide unmatched durability and power density for custom projects. With proper configuration, these cells enable ultra-fast charging solar arrays, subzero-temperature marine systems, and high-cycle EV battery banks. Their safety profile and modular scalability make them the premier choice for engineers prioritizing long-term reliability over initial cost.
FAQ
- Q: Can I mix Yinlong LTO with other battery types?
- A: No – differing voltage curves and charge profiles will cause system imbalances.
- Q: What torque for terminal connections?
- A: 4.5 N·m using M8 bolts – overtightening cracks the ceramic terminals.
- Q: Maximum parallel strings?
- A: 4P recommended; use fused links for higher parallelism.
