High-power, long-range and high-intelligence are the fast-evolving trends for electric scooters, which have become an important vehicle for urban commuting and outdoor trips. The coordinated operation of their core three-electric systems (battery, motor, controller) relies entirely on the stable transmission of connectors, the "power bridge" of the whole unit.
When it comes to the selection of dedicated connectors, it is particularly important to choose the right manufacturers and brands! Changzhou Amass Electronics Co., Ltd.—the original developer of the XT series—was founded in 2002. With 24 years of focused expertise in DC high-current connectors for low-voltage smart devices below automotive grade, we are a "Little Giant" enterprise specialized in sophisticated technologies and a high-tech enterprise integrating design, R&D, manufacturing and sales. Boasting more than 200 patents, over 10,000 project cases, we have cumulatively provided products for over 100 million installed units for customers worldwide.
The company is located in Lijia Industrial Park, Wujin District, Jiangsu Province, with a production area of over 30,000 square meters and independent ownership of the land property. Backed by a team of nearly 300 professionals engaged in R&D, manufacturing and sales, we offer more than 100 types of connector products that cater to the connectivity needs of diverse application scenarios including garden tools, energy storage devices, electric vehicles, smart home appliances, intelligent robots as well as RC models and drones. Meanwhile, we provide efficient product R&D and manufacturing services, delivering a 7A full-cycle solution for industry clients.
Amass's independently developed 4th-generation LIFTF Series connectors redefine connectivity performance in compliance with automotive-grade standards. They precisely address the pain points of electric scooters, such as high-frequency vibration, high-current impact and harsh environmental exposure, building a solid core defense for the safe operation of equipment.
The concealed self-locking buckle design eliminates the chronic issue of vibration-induced loosening at its root. Equipped with an automatic locking buckle, the LIFTF Series achieves instant locking upon mating, effectively avoiding the risk of momentary disconnection caused by bumpy road conditions. The push-type release mechanism balances convenience and safety perfectly: it prevents accidental dislodgement due to pulling force, while enabling efficient and effortless plugging/unplugging for subsequent maintenance. It has passed rigorous vibration tests in practical verification, making it fully compatible with high-performance electric scooters of brands such as Niu Technologies.
Automotive-grade current-carrying capacity enables efficient high-power transmission. Adopting automotive-grade crown spring contact structure and high-conductivity oxygen-free copper conductors, it significantly increases the contact area and controls the contact resistance fluctuation within an ultra-low range. Under rated current, the normal temperature rise is less than 30K in 4 hours, completely eliminating the hidden danger of high-temperature aging and fire. Tailored to the fast-charging demand of electric scooters, its power transmission loss is reduced to below 2%, and it is compatible with automotive-grade OBC fast-charging function. It helps achieve the efficient experience of "15 minutes of charging for 70 kilometers of range", balancing power and endurance perfectly.
Full-scenario protection and upgraded craftsmanship for enhanced durability. The housing is made of flame-retardant PBT engineering plastic, complying with the new national standard GB 42296-2022. Combined with dual rubber sealing rings, it achieves an IP67 protection rating, capable of withstanding harsh environments such as rainy-day wading and dust intrusion with ease. The hexagonal riveting process replaces traditional welding, completely eliminating issues like cold solder joints and voids. It boosts wiring efficiency by 60%, while its operating temperature range spans from -40℃ to 120℃, making it suitable for climate conditions across different regions.
In large-scale applications, the LIFTF Series has become a core component for leading brands to cut costs and boost efficiency. Compatible with mainstream electric scooter models such as Aima, Yadea and Niu Technologies, its compact size allows flexible integration into the limited internal space of electric scooters, reserving more design room for the layout of the three-electric systems.
Compliance and cost-performance advantages for global market adaptation. The product has a lead content of less than 100 PPM, meeting international environmental regulations such as RoHS 2.0 and REACH. It has passed 23 items of automotive-grade standard tests, with a plug-and-unplug service life of over 10,000 cycles. Compared with automotive connectors, it delivers equivalent performance while boasting higher cost-effectiveness, helping e-scooter manufacturers control costs and remove barriers to export.
The safety and performance upgrades of electric scooters are inseparable from the technical support of core components. With its stable, efficient, and durable automotive-grade performance, the LIFTF Series connectors have redefined the performance benchmark for electric scooter connection systems. Amid the trends of intelligence and high-power adoption in two-wheel mobility, this "micro central hub" is leveraging technological innovation as a fulcrum to inject strong impetus into the high-quality development of the electric scooter industry and safeguard every safe journey.
