The “High-Capacity Legend”: GREE Yinlong 66160K 45Ah If you are looking for the absolute best performance in the 66mm cylindrical format, the GREE 66160K 45Ah is the superior choice. As the enhanced successor to the world-famous 66160H, this cell maximizes the energy density of Lithium Titanate technology without compromising on the extreme safety and longevity that GREE is known for.
⚡ 12.5% More Capacity: Get more runtime and a larger power reserve in the exact same physical size as the 40Ah model. This makes it the premier choice for range-limited AGVs and high-density industrial battery banks.
⚡ 10C Discharge (450A Burst): Built for high-torque demands, this cell delivers a massive 450A pulse. It handles the most aggressive startup currents of heavy diesel trucks and industrial machinery effortlessly.
⚡ Legendary 25,000 Cycle Life: Retains the incredible durability of the Yinlong family. One installation is typically enough to cover the entire 20-30 year service life of the equipment it powers.
⚡ Easy Assembly (M12 Studs): Features integrated screw terminals (studs) that allow for rapid connection using only nuts and busbars, eliminating the need for expensive laser welding equipment.
✅ Strict Performance Testing: We don’t just ship batteries; we ship performance. DLCPO tests every single cell for voltage, internal resistance, and capacity before shipping to ensure you receive a perfectly matched set.
🎯 Direct Source Sourcing: We supply genuine Grade A GREE (formerly Yinlong) 66160K cells with scannable factory QR codes and verified manufacturing dates.
🌐 Global DDP Logistics: We handle the complex “Dangerous Goods” protocols for international shipping. Our DDP (Delivered Duty Paid) service to the USA, Europe, and Brazil makes importing industrial-grade lithium power seamless and tax-inclusive.
We do not recommend mixing different capacities in the same series string. While they look identical, the 45Ah cells will charge and discharge at different rates, leading to early pack imbalance. For the best performance, always build a new pack with matched 45Ah cells.
The cell body length is 161mm, but you must account for the M12 screw terminals. The total length is 209.5mm. We recommend allowing an extra 5-10mm for busbar routing and insulation caps.
Absolutely. GREE LTO cells are famous for their -40°C cold resilience. Unlike LFP batteries that cannot charge below freezing, the 66160K maintains excellent power delivery and recharge capability in extreme winter conditions. ❄️
