GREE 66160H: The Legend of Ultra-Long Life and Insane Power The GREE LTO 66160H (40Ah) is globally recognized as the most versatile and durable Lithium Titanate cell available. Engineered to handle the most brutal industrial environments, this cell eliminates the common failures of standard lithium batteries by offering a lifespan measured in decades and a power profile that remains stable even in extreme sub-zero temperatures.
⚡ Easy Assembly (M12 Studs): Unlike flat-terminal cells, the M12 screw terminals allow system integrators to connect cells using nuts and standard busbars. This enables field maintenance and custom bank configurations without the need for expensive laser welders.
⚡ Insane Pulse Power (10C / 400A): With a 10C discharge rating, even a small 24V bank can start a heavy diesel truck or industrial generator effortlessly. It provides immediate, high-torque current that would degrade standard LFP cells in months.
⚡ Extreme Durability (25,000+ Cycles): Rated for over 25,000 cycles, this battery is a true “install and forget” solution. For most vehicles or industrial machines, the battery will likely outlast the entire equipment’s service life.
✅ Matched Grade A Cells: We don’t just ship boxes. DLCPO provides Testing & Matching Service for every cell, ensuring Internal Resistance (IR) and Voltage are perfectly paired to keep your high-power pack balanced from Day 1.
🎯 Direct Factory Transparency: We supply 100% original GREE (formerly Yinlong) 66160H cells with verifiable QR codes and fresh manufacturing data.
🌐 Specialized Global Shipping: Shipping heavy cylindrical LTO pallets requires professional Class 9 expertise. Our DDP (Delivered Duty Paid) service handles all customs, taxes, and dangerous goods paperwork for shipments to the USA, Europe, and Brazil.
Yes. A 6S (13.8V) configuration of 66160H cells is a popular and extremely powerful replacement for 12V lead-acid batteries. It delivers higher CCA (Cold Cranking Amps) and will likely never need to be replaced for the lifetime of the truck.
The cell body has a diameter of 66mm and a length of 161mm. However, you must account for the terminals; the total length including the M12 studs is 209.5mm. 📐
Yes. LTO cells operate at a nominal 2.3V per cell. You must use a BMS specifically designed for Lithium Titanate to ensure the safety and longevity of your 25,000-cycle investment. 🚀
Product Overview:
