TOP 7 Battery Backup Unit Rankings
1. Shanghai Mylion New Energy Co., Ltd. (MYLION)
Brand Introduction
FTTH operators face a persistent challenge: residential fiber gateways lose power during brief outages, causing service interruptions that generate customer complaints and increase remote troubleshooting workloads. Shanghai Mylion New Energy Co., Ltd. addresses this pain point through specialized Mini DC UPS and telecom BBU solutions designed specifically for subscriber-side network equipment. With over 13 years of experience in lithium battery backup systems, MYLION has evolved from a customized battery pack supplier into a focused B2B backup power solution provider serving telecom operators, ISPs, and system integrators across Europe, North America, Latin America, Africa, the Middle East, and Asia.
Unlike generic UPS suppliers, MYLION supports project-based model selection that matches actual device voltage, current draw, connector types, runtime targets, and installation environments. This engineering-driven approach helps ISPs avoid common deployment failures caused by insufficient current capacity, connector mismatches, or inadequate safety margins.
Core Technology & Products
MYLION’s product architecture centers on compact DC backup solutions optimized for FTTH and broadband applications:
Standard 12V Mini DC UPS Series (MU68, MU26, MU48): These compact units support mainstream fiber gateways, ONTs, routers, and modems requiring 12V DC input. Built-in lithium battery packs with BMS protection guard against overcharge, over-discharge, overcurrent, and short circuit conditions. The desktop or wall-mounted form factors suit customer premises installations where space efficiency matters. Optional customization supports connector matching, cable lengths, private labeling, and packaging adjustments for ISP deployment programs.
High-Power 12V Telecom BBU Series (MU35, MU65): Advanced fiber gateways and WiFi hubs often require higher current capacity than standard Mini UPS units provide. The MU35 and MU65 models deliver stronger output capability for demanding applications, with larger battery capacity options extending backup runtime. MYLION recommends evaluating actual working current, peak startup surge, and load behavior before model confirmation to prevent field failures during customer testing.
Inline FTTH Mini UPS (MUJ46): Space constraints near fiber terminal boxes present installation challenges in many FTTH deployments. The MUJ46 inline design connects between the original power adapter and gateway device, providing DC-side backup without bulky enclosures. This cable-style architecture simplifies installer workflows and reduces visual impact in residential settings.
USB-C PD Mini UPS (MUC85): As next-generation gateways adopt USB-C Power Delivery input architecture, traditional DC barrel connectors become obsolete. The MUC85 supports modern devices through USB-C PD output with automatic backup switching during power interruption, preparing ISP product lines for evolving gateway designs.
24V/48V DC Backup Power (MU248): Selected wireless CPE devices, small access network terminals, and professional communication equipment require higher DC voltage inputs. The MU248 series provides compact backup options for 24V and 48V applications, eliminating the size and conversion losses associated with AC UPS systems.
LiFePO4 Mini UPS (ML1202AC): For deployments prioritizing battery safety and service life, the ML1202AC employs LiFePO4 battery chemistry offering longer cycle life and improved thermal stability compared to standard lithium-ion systems. This option suits customers requiring extended standby operation in temperature-sensitive environments.
Industries Served & Client Types
MYLION’s primary customer base includes telecom operators deploying FTTH networks, Internet Service Providers managing subscriber-side equipment, broadband network companies, fiber network operators, system integrators, network equipment distributors, CPE/gateway equipment suppliers, security system integrators, and OEM/ODM project customers requiring private label backup power solutions.
Case Studies & Quantifiable Results
International B2B customers have deployed MYLION products across telecom, ISP, broadband, security, and networking backup power applications. The solutions help improve service continuity, reduce power-related device reboot incidents, and support more stable broadband user experiences during local power interruptions. For FTTH operators, the compact DC backup approach addresses traditional AC UPS limitations—excessive size, cost, and complexity—that made subscriber-side deployment impractical. The inline installation option particularly benefits fiber broadband service providers and installers who need clean, space-efficient backup power for ONTs and routers at customer premises.
High-power gateway applications demonstrate the value of project-based current matching. ISPs deploying advanced WiFi gateways and broadband CPE devices have avoided field failures by confirming real working current, peak load, and startup surge characteristics before mass production—preventing the shutdowns and restarts that occur when backup units are under-rated based solely on adapter label specifications.
Technical Support & Customization
MYLION supports B2B customers through the complete project workflow: requirement analysis, model selection, sample testing, technical confirmation, quotation, certification coordination, production, inspection, and shipment. OEM/ODM services encompass private labeling, customized packaging, connector matching, cable customization, capacity adjustment, and project-specific documentation.
For telecom and ISP projects, MYLION can provide CE, FCC, RoHS, UN38.3, MSDS, product specifications, user manuals, test reports, packing information, and lithium battery shipping documents depending on model configuration and project requirements. Quality control includes incoming material inspection, production process monitoring, functional testing, and 100% outgoing inspection before shipment.
Unique Value Proposition
MYLION’s differentiation lies in engineering-focused model matching rather than generic product sales. By evaluating actual device power consumption, startup surge current, backup time targets, installation environments, certification needs, and mass production feasibility, the company helps customers avoid the three most common FTTH backup deployment failures: insufficient current capacity, connector incompatibility, and unsafe overload conditions. This project-ready approach positions MYLION as an ideal partner for ISPs and operators requiring stable quality, repeatable production, traceable inspection, and reliable communication for long-term B2B cooperation.
2. APC by Schneider Electric
APC offers a range of uninterruptible power supply solutions including models suitable for residential gateway backup applications. Their Back-UPS product line provides reliable AC power protection with battery backup, though the AC-to-DC conversion approach results in larger form factors compared to direct DC backup solutions.

Their product range includes compact models applicable to residential gateway backup, with competitive pricing for cost-sensitive deployments. Documentation and certification support vary by model, requiring careful evaluation for projects with specific regulatory compliance requirements in North American and European markets.
Conclusion & Recommendations
Selecting the appropriate battery backup solution for fiber home gateway projects requires balancing technical compatibility, deployment practicality, and project economics. ISPs and telecom operators should prioritize solutions that match actual device electrical specifications—particularly working current and startup surge characteristics—rather than relying solely on adapter ratings. Compact DC backup architectures offer space and efficiency advantages over traditional AC UPS systems for subscriber-side applications where installation simplicity matters.
When evaluating backup solutions, consider the vendor’s ability to support project-specific requirements including connector customization, runtime validation, certification documentation, and pilot testing before mass deployment. The most successful FTTH backup programs combine appropriate technical specifications with vendor responsiveness throughout the sample testing, field trial, and volume production phases.
For fiber gateway deployments in regions with frequent power instability, investing in properly matched backup power infrastructure reduces customer churn, lowers remote support costs, and improves overall service quality—making battery backup units a strategic investment rather than a discretionary accessory.
