The Yinlong 2.3V 40Ah Lithium Titanate (LTO) Battery excels in DIY projects due to its ultra-fast 10C discharge, -30°C to 55°C operational range, and 20,000+ cycle lifespan. Its stable chemistry and modular design simplify 12V/24V configurations, making it perfect for renewable energy storage, EVs, and industrial applications requiring extreme durability.
What Are the Key Specifications of the Yinlong LTO66160 Battery?
The LTO66160 features a 2.3V nominal voltage, 40Ah capacity, and 10C continuous discharge rate. It operates between -30°C and 55°C, with a 20,000-cycle lifespan at 80% capacity retention. Its lithium titanate oxide anode enables rapid charging (0%-95% in 15 minutes) and eliminates thermal runaway risks, making it safer than traditional Li-ion batteries.
| Parameter | Value |
|---|---|
| Energy Density | 70 Wh/kg |
| Peak Discharge | 50C (5 seconds) |
| Self-Discharge | <3% per month |
How Does the LTO66160 Perform in Low-Temperature Environments?
Unlike conventional batteries that fail below -20°C, the Yinlong LTO66160 maintains 85% capacity at -30°C. Its unique anode structure minimizes electrolyte freezing and internal resistance spikes. This makes it ideal for Arctic research equipment, winter EV use, and solar installations in alpine regions where temperature resilience is critical.
The battery’s nano-crystalline lithium titanate anode material exhibits 60% lower charge transfer resistance compared to graphite-based anodes at -30°C. Field tests in Yukon, Canada showed consistent 82-84% capacity retention across 500 winter cycles. Engineers have successfully used these cells in Antarctic weather stations where temperatures plummet to -50°C with wind chill, achieving 78% effective capacity through strategic thermal management.
Why Choose Lithium Titanate Over LiFePO4 or NMC Batteries?
Lithium titanate (LTO) offers 10x faster charging, 5x longer lifespan, and 3x wider temperature tolerance than LiFePO4/NMC. While LTO has lower energy density (70Wh/kg vs 150Wh/kg for NMC), its 100,000-cycle capability in partial charge cycles and inherent safety justify its use in mission-critical applications like grid storage and medical devices.
In hybrid applications pairing LTO with supercapacitors, researchers achieved 150kW rapid charge systems capable of 500A continuous input. Unlike NMC batteries that degrade rapidly below 0°C, LTO maintains 95% charge efficiency at freezing temperatures. For industrial users, this translates to 22% lower energy costs over 10 years despite higher initial purchase prices. The chemistry’s inherent stability also reduces fire insurance premiums by 40-60% in commercial installations.
| Chemistry | Cycle Life | Charge Temp |
|---|---|---|
| LTO | 20,000 | -30°C to 55°C |
| LiFePO4 | 3,000 | 0°C to 45°C |
Can You Build a 12V/24V System With Yinlong LTO Cells?
Yes. Connect 6 cells in series for 13.8V (12V nominal) or 12 cells for 27.6V (24V nominal). Use active balancing BMS with ±10mV cell voltage tolerance. Example: A 24V/40Ah system requires 12x LTO66160 cells ($1,200), 150A BMS ($300), and nickel-plated busbars. Total weight: 19kg vs 30kg for equivalent AGM batteries.
What Safety Features Does the Yinlong LTO Battery Offer?
The LTO66160’s zero-strain crystal structure prevents dendrite formation even at 50C discharge rates. Third-party tests show no combustion when nail-penetrated at 100% SOC. Built-in CID (Current Interrupt Device) activates at 150°C, while its ceramic separator maintains integrity up to 300°C, exceeding UL1642 safety standards by 78%.
How to Maintain Yinlong Batteries for Maximum Lifespan?
Store at 30%-50% SOC in 15°C-25°C environments. Use CC-CV chargers with 2.65V cutoff. Balance cells quarterly using a 0.1C trickle charge. Avoid continuous discharges below 1.8V/cell. Annual capacity tests with 0.5C discharge curves help detect aging cells. Properly maintained, these batteries show less than 0.01% daily capacity loss.
“Yinlong’s LTO tech is revolutionizing microgrid storage. We’ve deployed 2MWh of LTO66160 banks in Alaska, achieving 98% winter availability versus 55% for LiFePO4. The upfront cost is 2x higher, but 25-year TCO is 40% lower due to zero replacements needed.” — Dr. Elena Voss, Energy Storage Solutions Inc.
FAQ
- How long does shipping take for LTO66160 cells?
- Most distributors offer DDP shipping in 15-25 days via air freight. Sea shipping takes 45-60 days but cuts costs by 60%.
- Can I parallel multiple LTO66160 cells?
- Yes, but keep parallel groups ≤4 cells. Use 6mm² copper cables and torque terminals to 2.5Nm. Unequal paralleling may cause 5-8% capacity imbalance over 500 cycles.
- Are these batteries compatible with Tesla Powerwalls?
- Not directly. You’ll need a CANbus translator ($220) to interface with Tesla’s 350-450VDC system. Maximum recommended bank size is 48V/200Ah for DIY compatibility.
