Product Overview
The ECOLTO2407 is a 24V 7.8Ah lithium titanate (LTO) battery pack engineered for applications demanding unmatched cycle life, extreme temperature resilience, and absolute safety. With an exceptional lifespan exceeding 20,000 cycles, an operating range from -40℃ to 60℃, and superior thermal stability, it is the ideal power solution for solar trackers, medical instruments, LED street lighting, electric doors, and other critical systems where reliability and longevity are non-negotiable.
Unmatched Longevity & Cost Efficiency
Lithium titanate chemistry enables this battery to deliver over 20,000 cycles at 80% depth of discharge—far surpassing conventional LiFePO4 and lead-acid batteries. While the initial investment may be higher, the ultra-extended service life drastically reduces the frequency of replacements and lowers the total cost of ownership over the system's lifetime, offering superior long-term value.
Exceptional Safety & Thermal Stability
LTO is renowned as one of the safest lithium battery chemistries. It demonstrates outstanding stability under rigorous conditions, including nail penetration, compression, and short-circuit tests, with no risk of smoke, fire, or thermal runaway. This makes it a trusted choice for sensitive and unattended applications.
Wide-Temperature Operation for Harsh Environments
Capable of charging and discharging from -40℃ to 60℃, this battery performs reliably in extreme cold or heat. Whether installed in solar trackers exposed to desert sun or medical devices used in unheated environments, it ensures consistent power delivery without temperature-related performance drop-off.
Rapid Charge & High-Power Discharge
The battery supports fast charging with a maximum current of 23.4A and can deliver high pulse currents up to 280A for milliseconds, making it suitable for applications requiring quick energy bursts or frequent recharge cycles without compromising lifespan.
Versatile & Rugged Design
Housed in an IP54-rated ABS enclosure with M5 terminals, the pack is protected against dust and water splashes, suitable for both indoor and outdoor installations. Its compact form factor (223x95x175mm) and moderate weight (3.5kg) allow flexible integration into various equipment layouts.
