The “Little Beast”: GREE 9Ah LTO Cylindrical Power The GREE LTO 32140 is a legend in the DIY battery community. Despite its compact size, it packs a massive punch with 10C discharge capability (90A continuous burst), making it vastly superior to traditional 18650 or 21700 Li-ion cells for high-load power applications.
⚡ Extreme Longevity (18,000 Cycles): Rated for over 18,000 cycles, this battery is essentially an “install and forget” solution. In typical solar or audio use, it can easily provide over 20 years of reliable service life.
⚡ Superior Mechanical Safety: The rigid steel cylinder casing provides excellent physical protection and enhanced thermal dissipation compared to pouch or aluminum prismatic designs. It is built to handle the vibrations and heat of automotive environments.
⚡ Unmatched Flexibility: The cylindrical form factor makes it easier to fit into creative and tight spaces, such as under car seats, inside thin machinery bases, or in custom-shaped Car Audio battery banks.
✅ Matched Performance: We don’t just ship random cells. DLCPO provides Testing & Matching Service, pairing cells by voltage and internal resistance to ensure your finished battery pack is perfectly balanced and efficient.
🎯 Authentic Source Integrity: We source directly from GREE/Yinlong industrial distribution. You receive 100% genuine Grade A cells with scannable QR codes and fresh manufacturing dates.
🌐 Global Logistics Experts: Shipping cylindrical cells requires specialized packing protocols. Our DDP (Delivered Duty Paid) service to the USA, Europe, and Brazil covers all hazardous goods fees and customs duties, delivering your project power directly to your door.
Yes, this is one of their most popular uses! Because LTO can discharge and recharge at extremely high rates (10C), these cells are perfect for handling the rapid, massive current draws of high-wattage amplifiers without the voltage drops common in Lead-Acid or standard LFP batteries.
Each cell has a diameter of 32mm and a body length of 140mm. We recommend allowing an extra 2-3mm in your design for terminal connections and insulation heat shrink.
If you cycle the battery fully once every single day, 18,000 cycles would mathematically equate to over 49 years of service. It will most likely outlast the equipment it powers. 🔋
