Smart 42V 2A Lithium-Ion Battery Charger Power Adapter Set 

 AC 100–240V Universal Input, Auto-Cutoff LED Indicator & 5-in-1 Multi-Plug Connector Suite for 36V E-Bikes & Scooters

Keep your 36V electric bike, scooter, or hoverboard powered up safely with this Universal 42V 2A Smart Lithium-Ion Battery Charger. Engineered with an AC 100–240V wide-voltage input for global compatibility, this intelligent power adapter delivers a stable, CC/CV regulated 42V output specifically calibrated for charging 36V (10S nominal) lithium battery packs.

Equipped with automatic overcharge protection, short-circuit prevention, and reverse-polarity safeguards, this smart charger features a color-changing LED status indicator (Red = Charging, Green = Fully Charged / Disconnected) to preserve cell health. Choose the 5-in-1 Multi-Plug Option to instantly adapt your charger to virtually any standard e-mobility charging port on the market.

⚠️ Battery Compatibility & Safety Warning

STRICT BATTERY TYPE NOTICE:

  • Lithium-Ion Only: This charger is engineered EXCLUSIVELY for 36V Lithium-Ion (Li-Ion) battery packs (42V max charge cutoff).

  • DO NOT USE FOR LEAD-ACID: Never connect this charger to Lead-Acid, AGM, SLA, or Gel battery packs, as doing so may cause severe component damage.

  • Voltage Compatibility: Designed for 36V nominal lithium packs (also compatible with specified 24V–25.9V series lithium builds requiring a 42V charge profile).

🚀 Key High-Performance Features

  • Smart Auto-Cutoff Maintenance: Intelligently monitors battery voltage and stops charging automatically once full capacity is reached, preventing overcharging.

  • 5-in-1 Universal Multi-Plug Connector Suite (Optional): Converts the main 5.5mm DC plug into 8mm 3-Prong, 12mm 3-Prong, 8mm RCA, and 3-Pin XLR connectors.

  • Dual-Color LED Charging Status Display: Bright visual indicator turns red during active charging and transitions to green when full or idle.

  • Multi-Stage Electronic Safety Protections: Built-in safeguards defend against over-current, over-voltage, short circuits, and thermal spikes.

  • Worldwide AC Input Voltage: Operates seamlessly on AC 100–240V (50/60Hz) wall outlets with optional US or EU power cords.

⚙️ Operating Instructions & Connector Matching

  1. Verify Battery Voltage: Confirm your electric bike or scooter battery is rated at 36V nominal (42V max charge cutoff).

  2. Select Adapter Plug: If your device does not use a standard 5.5mm DC barrel port, snap the appropriate adapter plug (XLR, RCA, or 3-Prong) onto the main DC lead.

  3. Plug-In Sequence: Connect the DC output plug to your battery charging port first, then plug the AC power cord into the wall socket. Verify the LED turns RED. Disconnect when the LED turns GREEN.
