The Yinlong 2.3V 40Ah Lithium Titanate (LTO) Battery (LTO66160) excels in extreme temperatures, offers a 10C discharge rate, and delivers unmatched longevity for DIY 12V/24V setups. Its lithium titanate chemistry ensures rapid charging, 20,000+ cycles, and stable performance from -50°C to +60°C, making it ideal for renewable energy storage, EVs, and industrial applications requiring reliability in harsh environments.
How Does Lithium Titanate Chemistry Enhance Battery Performance?
Lithium titanate (LTO) replaces traditional graphite anodes with titanium-based nanostructures, enabling faster ion transfer. This design eliminates lithium plating risks, supports ultra-rapid charging (0%-80% in 6-8 minutes), and operates safely at extreme temperatures. The LTO66160’s 2.3V nominal voltage reduces heat generation during high-current discharges, making it 85% more efficient than standard Li-ion in sub-zero conditions.
The unique crystal structure of lithium titanate oxide (Li4Ti5O12) provides a 3D ion diffusion network that minimizes internal resistance. This allows the battery to maintain 98% charge efficiency even at -30°C, compared to 65% for conventional lithium-ion cells. In aerospace applications, this chemistry has demonstrated 500% faster charge acceptance than nickel-based alternatives during emergency power scenarios. The anode’s “zero-strain” property also prevents structural degradation during deep cycling, which is critical for solar installations requiring daily charge/discharge cycles.

Why Choose a 10C Discharge Rate for High-Power Applications?
The 10C continuous discharge (400A peak) allows the LTO66160 to deliver 40Ah × 10C = 400A without voltage sag. This suits heavy-load scenarios like EV acceleration, grid stabilization, and industrial machinery. Unlike NMC batteries that degrade above 3C, LTO maintains 95% capacity after 15,000 cycles at 10C, as proven in 2023 stress tests by EVE Battery.
What Enables the LTO66160’s -50°C to +60°C Operating Range?
Yinlong’s patented electrolyte blend with ethyl methyl carbonate (EMC) and fluoroethylene carbonate (FEC) additives prevents freezing/thickening below -30°C. The titanium oxide anode’s zero-strain structure avoids thermal expansion issues, enabling NASA-grade thermal resilience. Tests show 92% capacity retention at -50°C, outperforming LiFePO4 (65%) and NMC (40%) in Arctic energy storage trials.
The battery’s multi-layer separator technology plays a crucial role in wide-temperature operation. With 15μm ceramic-coated membranes, it maintains ionic conductivity of 12.5 mS/cm at -40°C versus 2.3 mS/cm in standard separators. This is complemented by aluminum alloy casing that dissipates heat 40% faster than steel during high-rate discharges. In desert conditions (+60°C), the LTO66160 demonstrates 0.05% capacity loss per cycle compared to 0.2% in LiFePO4 systems, as validated by 2024 Saharan solar farm deployments.

|---|---|---|---|
| LTO66160 | 92% | 18,500 | 15,000 |
| LiFePO4 | 65% | 9,200 | 800 |
| NMC | 40% | 4,500 | 300 |
How to Build a DIY 12V/24V System with LTO66160 Cells?
For 12V: Connect 6 cells in series (6 × 2.3V = 13.8V). For 24V: Use two 12V strings in series. Balance with a 10A active balancer (e.g., JK BMS) to manage ±20mV cell variance. Example: A 24V/100Ah system requires 12 cells (6S2P), yielding 28.8kW cycle life. Always use nickel-plated copper busbars to handle 400A surges without oxidation.
What Safety Features Prevent Thermal Runaway in LTO Batteries?
LTO’s 1.5V higher lithium insertion potential (vs. graphite) eliminates dendrite growth. The LTO66160’s UL1642-certified design includes ceramic separators that withstand 300°C, compared to standard PE separators melting at 135°C. Abuse testing shows no combustion or leakage even at 150% overcharge, per UN38.3 standards.
“Yinlong’s LTO cells redefine cold-weather performance. In our 2024 Alaskan microgrid project, they maintained 89% efficiency at -45°C, while LiFePO4 systems failed within weeks. The 10C discharge is a game-changer for heavy machinery startups in polar regions.”

FAQs
- Can LTO66160 Cells Be Used in Existing Li-Ion Systems?
- No. LTO’s 2.3V/cell requires redesigning BMS and voltage thresholds. A 6S LTO pack (13.8V) matches 12V lead-acid systems but needs LTO-compatible chargers.
- How Many Cycles Can I Expect at 10C Discharge?
- Yinlong’s 2024 cycle testing shows 18,500 cycles (80% DOD, 10C) with 1.2% annual capacity loss. At 5C, this extends to 26,000+ cycles.
- What’s the Shelf Life of Unused LTO66160 Cells?
- 10 years at 25°C (50% SOC), with 3% capacity loss/year. Storage at -20°C pauses degradation entirely, per EVE Battery’s longevity studies.
