SPBC4802A Li-ion Battery Charger, 54.6V 2.0A 100–240VAC Rosenberger RoPD Magnetic DC Connector

SPBC4802A Li-ion Battery Charger, 54.6V 2.0A CC/CV Output, Universal 100–240VAC Input, Fanless Design with Rosenberger RoPD Magnetic DC Connector, Multi-Protection & Global Safety Marks for 13-Series (48V nominal) Packs

Condition: Appears used; minor cosmetic wear from prior handling. No original packaging. Power cord included

This SPBC4802A is a compact, fanless lithium-ion charger engineered for 13-series (48V nominal) Li-ion/Li-poly battery packs. It delivers a constant-current/constant-voltage (CC/CV) charge profile at 54.6V DC / 2.0A, the correct full-charge voltage for 13S cells (13 × 4.2V). Universal 100–240VAC, 50/60Hz input supports worldwide use, while built-in protections—OVP, OCP, SCP, reverse-polarity—help safeguard both charger and pack. A Rosenberger RoPD magnetic connector on the DC lead provides a quick, self-aligning, breakaway interface commonly seen on e-mobility, robotics, and medical carts. Compliance badges include UL, GS/CE, CB, KC, PSE, RoHS, and REACH (markings present on unit).

Features

• 54.6V / 2.0A CC/CV output: Optimized for 13S Li-ion battery packs (48V nominal).
• Universal AC input: 100–240VAC, 50/60Hz for global mains.
• Fanless aluminum enclosure: Quiet operation; fewer moving parts to fail.
• Rosenberger RoPD magnetic DC connector: Self-aligning, quick-release, polarity-keyed; reduces wear on jacks.
• Protection suite: Over-voltage, over-current, short-circuit, and reverse-polarity protection.
• Safety & environmental markings: UL, GS/CE, CB, KC, PSE, RoHS, REACH (as labeled).
• Status indication: Typical LED (charge/ready) behavior; exact indications may vary by revision.

Specifications

Applications / Spheres of Use

• E-bikes / E-scooters / 48V mobility packs (13S).
• AGV/AMR robots, warehouse carts, service robots using 48V Li-ion.
• Medical/industrial carts (where a magnetic breakaway DC plug is preferred).
• Portable power stations, LED towers, test benches utilizing 13S packs.

Cross-Referenced / Interchange (by function & output)

• Other 54.6V 2A Li-ion chargers for 13S packs with different DC connectors (XT60, GX16, 3-pin, DC barrel).
• Chargers using Rosenberger RoPD magnetic leads with the same 54.6V CC/CV profile (verify pinout and polarity).
  (Always confirm connector type/pinout and battery manufacturer’s charge limits before substituting.)

Comparable Products

• 54.6V 2–3A Li-ion desktop chargers from industrial vendors with universal AC input and multi-protection features.
• Higher-power options (54.6V 4–8A) for faster charge—use only if your pack/BMS allows the higher current.
• Smart chargers with CAN/SMBus when packs require communication (this model is standalone CC/CV).

Use in Larger Systems / Integration Notes

• BMS compatibility: Ensure your battery’s BMS supports 54.6V termination and ≥2A charge current.
• Connector check: Match RoPD gender/orientation and polarity to the pack inlet; mis-match can trigger reverse-polarity protection.
• Thermal placement: Fanless chassis benefits from free airflow; avoid covering or mounting in sealed hot compartments.
• Charge protocol: For longevity, many OEMs recommend charging to ≤54.0V or limiting current at high SOC—follow your pack spec.
