Frequently Asked Questions
Q: What makes LTO (Lithium Titanate) batteries different from regular lithium-ion batteries?
A: LTO (Lithium Titanate) batteries use a lithium titanate anode instead of graphite, which gives them exceptional advantages: an extremely long cycle life (20,000+ cycles vs. ~500–2,000 for standard Li-ion), the ability to charge and discharge in temperatures as low as -40°C, a higher safe discharge rate, and improved overall safety. They are ideal for applications that demand longevity, high current, and reliability in extreme conditions.
Q: How many cells do I need to build a 12V or 24V battery pack with these 2.3V LTO cells?
A: To build a nominal 12V pack, you would connect 5 cells in series (5S × 2.3V = 11.5V nominal; 5 × 2.8V = 14V fully charged). For a nominal 24V pack, connect 10 cells in series (10S). The cells support 5S, 10S, 15S, 20S, and other series configurations to suit your target voltage.
Q: Can this LTO battery cell be used for solar energy storage?
A: Yes — the Yinglong 66160 40Ah LTO cell is an excellent choice for solar energy storage. Its wide operating temperature range, fast charge capability (up to 30A), and 20,000+ cycle life make it well-suited to absorb and discharge solar energy day after day without significant capacity degradation over many years.
Q: What is the maximum discharge current for this cell?
A: The cell supports a continuous discharge rate of 5C (200 Amps) and a peak/maximum discharge rate of 15C (600 Amps), making it suitable for high-demand car audio builds, EV motor starts, and other high-current burst applications.
