stio 54.6V 2A eBike Charger for 48V Lithium Batteries — 5.5×2.1mm Plug, ETL‑Certified Fast Charge

Fast, ETL‑certified 54.6V 2A charger from stio designed to safely recharge 48V lithium eBike batteries (Lectric XP series and similar) with a 5.5×2.1mm DC plug.

If you ride a 48V eBike such as the Lectric XP 1.0/2.0/3.0, Lectric XPremium, or compatible models from SAMEBIKE and KUGOO, this stio charger offers quicker charging, multiple safety protections, and a durable housingspec built for daily use. It balances faster amperage with industry safety certifications so batteries charge more quickly without sacrificing protection.

How much faster will this charger refill my 48V battery?

The stio unit delivers up to 2.0A (54.6V), increasing charge power compared with lower‑amp chargers to reduce downtime. Actual charging speed depends on your battery capacity and its built‑in battery management system (BMS).

• Maximum output: 54.6V at 2.0A (≈109.2W peak power).
• Faster options cascade: 2.0A > 1.7A > 1.5A > 1.2A etc., adapting as needed.
• Works best with compatible 48V lithium packs like Lectric XP series.

What safety features protect my bike and home?

This charger is ETL listed and includes a suite of protections to reduce electrical and thermal risks. It’s designed with materials and cooling systems to lower the chance of overheating or short circuits during normal use.

• Certified by ETL for electrical safety compliance.
• Built‑in protections: short‑circuit, over‑voltage, over‑temperature, overload.
• IP65‑rated resistance to dust and low‑pressure water jets for added durability.

How durable is the charger for everyday riding and storage?

stio combined a one‑piece flame‑retardant ABS shell with heavy‑gauge copper wiring and dual cooling to improve longevity. The casing and materials prioritize safety and heat dispersion so the charger remains stable during repeated cycles.

• Dual cooling: silicone thermal interface plus aluminum heat dissipation.
• 18AWG pure copper cable for reliable current delivery and low loss.
• Solid ABS housing resists impacts and reduces fire risk.

Which eBike models and connector types are supported?

The charger uses a standard DC 5.5×2.1mm plug and supports many 48V eBike models with that barrel connector. Verify your bike’s required voltage and connector size before purchase to ensure compatibility.

• Compatible: Lectric XP (1.0, 2.0, 3.0), XP Step‑Thru variants, XP Lite, Lectric XPremium.
• Also compatible with SAMEBIKE 20LVXD30/LO26, KUGOO C1, KUGOO G2 PRO and similar 48V systems.
• Connector: DC 5.5mm outer × 2.1mm inner barrel plug.

Who is this for: Riders who want a faster, reliable replacement or spare charger for 48V lithium eBike batteries, especially owners of Lectric XP series and comparable bikes. It’s suited for commuters, weekend riders, and anyone needing an ETL‑listed charger with robust safety features and IP65 environmental protection. If you require a different connector or voltage, double‑check your bike’s specifications before ordering.
