The ECOLTO LTO series is a premium range of lithium-titanate (LTO) batteries engineered for extreme reliability and long-lasting performance in demanding environments. Boasting an exceptional cycle life of over 25,000 cycles, these cells support ultra-fast 20C rapid charging and discharging rates while maintaining an extremely low risk of rupture or ignition. Designed to operate seamlessly across a wide temperature range from -40°C to 100°C, the series features a rated operating voltage of 1.5V to 2.8V and demonstrates remarkable stability under stress—retaining ≥85% of initial capacity after 200 high-temperature cycles at 90°C, and ≥70% of initial capacity after 1,000 hours of high-temperature (90°C, 90% RH) storage. The standard product lineup includes three compact models: the LTO 0412 (3mAh, 4x12mm), the LTO 0415 (6mAh, 4x15mm), and the larger-capacity LTO 0820 (30mAh, 8x20mm). With ultra-low ESR values (as low as ≤200mΩ) and maximum continuous discharge currents reaching up to 600mA, these robust batteries are ideally suited for compact industrial equipment, automotive electronics, and IoT devices that require dependable power in harsh conditions.
