CHARGEX® 48V 150AH Lithium Telecom Battery
ALP-248 Compatible · SiFi FiberCity® Edition
The CHARGEX CXN48150-V248 is the field-proven, custom-engineered 48V lithium iron phosphate (LiFePO4) battery solution developed in close collaboration with SiFi Networks and Nokia, for reliable backup power in streetside telecom cabinets and aggregation huts. This prismatic-cell battery was specifically designed, iterated, tested, and qualified to meet the rigorous demands of SiFi's FiberCity® deployments, delivering superior runtime, hot-swap capability, earthquake resistance, and environmental protection compared to traditional VRLA lead-acid systems.
Key Features & Advantages
Nokia-Qualified & ALP-248E Compatible
Fully tested and approved for integration into ALP-248E streetside cabinets — no modifications required — and Nokia-integrated fiber networks.
SiFi Networks FiberCity® Proven
Deployed and validated across multiple live FiberCity® projects including Simi Valley (CA), Oceanside (CA), Escondido (CA), and Farmington Hills (MI).
Hot-Swap Ready
Seamless field exchange: one battery powers the load while the second is swapped, eliminating downtime.
Extended Runtime
>12 hours full cabinet load support (paired 300Ah configuration); >6 hours at 50A discharge.
Earthquake-Resistant Design
Customized mounting brackets on existing cabinet beams and custom restraints engineered for seismic stability.
Rugged IP-Rated Enclosure
Durable anodized aluminum enclosure provides superior corrosion resistance and scratch protection. Recessed IP68 Anderson connectors (non-protruding, perpendicular mating), dual recessed handles (front + lid).
High Cycle Life & Advanced Safety
>6,000 cycles (80% capacity after 5,000 at 100% DOD). BMS with cell balancing, OVP/UVP, OCP, short-circuit protection, auto-recovery, NSD (nail-penetration thermal runaway prevention), and OSD (overcharge fuse protection).
Fast Charging
Compatible with 5kW rackmount chargers — 0 to 90% SOC in under 90 minutes. >90% round-trip efficiency.
Lightweight & Modular
130 lbs per unit. Series connections up to 96V or unlimited parallel configurations.
