Yinlong 2.3V 40Ah/45Ah lithium titanate (LTO) batteries excel in DIY auto audio setups due to their extreme temperature resilience (-50°C to +60°C), 10C discharge rate for high-power demands, and modular design enabling 12V-128V configurations. Their 20,000+ cycle lifespan ensures long-term reliability for premium sound systems.
How Do Yinlong LTO Batteries Enhance Auto Audio Performance?
Yinlong’s low internal resistance (≤0.8mΩ) minimizes voltage drop during bass-heavy passages, maintaining consistent power delivery. The 10C continuous discharge (400A peak) supports high-wattage amplifiers without sag, while ultra-fast charging (15 minutes to 80%) prevents downtime during competitions or extended listening sessions.
What Are the Key Specifications of Yinlong 40Ah Batteries?
Key specs include: 2.3V nominal voltage, 40Ah/45Ah capacity variants, 10C continuous/15C pulse discharge, 100% depth of discharge capability, and 3-minute fast-charge readiness. Each prismatic cell weighs 1.7kg with dimensions 175x130x27mm, using lithium titanate chemistry for unparalleled thermal stability.

The lithium titanate anode’s zero-strain structure enables exceptional cycle stability, with capacity retention exceeding 90% after 15,000 cycles in vibration-intensive automotive environments. This chemistry also eliminates thermal runaway risks, maintaining safe surface temperatures below 60°C even during 15C pulse discharges.
How to Safely Install Yinlong Batteries in Vehicles?
Use marine-grade tinned copper lugs (70mm² minimum), ceramic terminal covers, and fire-retardant ABS battery boxes. Maintain 15mm inter-cell spacing for airflow. Ground the BMS to chassis via 10AWG wire. For 128V systems, install visible high-voltage warning labels and use reinforced insulation on all cables.
| System Voltage | Wire Gauge | Fuse Rating |
|---|---|---|
| 12V-48V | 4 AWG | 300A ANL |
| 64V-128V | 2/0 AWG | 600A MRBF |
Always use torque-limiting tools when connecting terminals – overtightening beyond 5.5Nm can damage the stainless steel threads. For multi-bank configurations, implement current-sharing busbars with 1.5x overspec thickness to minimize resistance. Install moisture-wicking silica gel packets in battery enclosures to prevent condensation in humid environments.
Why Choose Yinlong Over EVE Batteries for Car Audio?
While EVE’s LF105 (3.2V 105Ah LiFePO4) offers higher energy density, Yinlong dominates in power density (4,500W/kg vs 1,200W/kg) and temperature range. Yinlong maintains 95% capacity at -30°C versus EVE’s 70% drop. For SPL competitions requiring instant 500A+ bursts, Yinlong’s LTO chemistry outperforms.
What Maintenance Extends Yinlong Battery Lifespan?
Monthly: Check terminal torque (4.5-5.0Nm). Quarterly: Calibrate BMS SOC. Annually: Perform deep discharge/recovery cycle. Avoid persistent 100% SOC storage – store at 2.15V/cell (50% SOC) using maintenance chargers. Wipe cells with anhydrous ethanol to prevent terminal oxidation.
Expert Views
“Yinlong’s LTO tech revolutionizes mobile audio. We’ve tested 128V systems sustaining 158.2dB SPL for 45 seconds straight – competitors’ LiFePO4 cells overheated within 15 seconds. The key is the anode’s spinel structure that prevents lithium plating even at -50°C.” – Dr. Erik Voll, Electrochemical Systems Engineer
FAQ
- Can Yinlong Batteries Power 10,000W RMS Systems?
- Yes. A 64-cell 128V/40Ah configuration delivers 5,120Wh – sufficient for 10kW RMS systems running 30-minute demos. Use dual 600A BMS units in parallel for current sharing.
- Do Yinlong Cells Require Heating in Winter?
- No. Unlike LiFePO4, Yinlong cells maintain 85% capacity at -30°C without external heating. Testing shows successful cold cranking at -45°C.
- How to Recycle Yinlong LTO Batteries?
- Return to certified LTO recyclers like Redux GmbH. The titanate anode is non-toxic, but electrolyte (1.2M LiPF6 in EC/DMC) requires professional handling. Recycling efficiency reaches 98% for cobalt-free cathodes.
