Efficient, reliable charging for 72V Li‑ion packs

The TANGSPOWER TP-672W-840080 is a smart 84V charger designed to support 20S 72V Li‑ion battery packs connected in series. It blends broad input compatibility, robust protection, and a clear status display to help you manage charging sessions with confidence in homes, garages, or workshops.

Smart performance you can rely on

  • AC input range of 100–240Vac at 50–60Hz with PF > 0.99, enabling versatile use across regions.
  • DC output 84V at 8A, tailored for 72V packs to deliver balanced charging.
  • High‑efficiency LLC with synchronous rectification, achieving up to 94.5% efficiency to reduce heat and energy loss.
  • Comprehensive protection including undervoltage, overvoltage, over‑current, short‑circuit, battery reverse activation, backflow prevention, and over‑temperature safeguards.
  • LCD display shows charging status and can reveal current voltage, current, power, and capacity; the charging current can be adjusted to fit your needs.

Real‑time monitoring and automatic safety

The integrated LCD panel provides a live readout of the charging process. You’ll see how fast the pack is charging, the voltage being applied, the current, and the accumulated capacity. The charger also automatically stops charging when the battery reaches full capacity, helping you manage sessions with minimal attention.

Safe usage and practical placement

  • Place the charger on a flat, dry surface in a well‑ventilated area; keep it away from moisture and direct heat.
  • Maintain ambient temperatures between -10°C and 45°C; avoid flammable materials and direct sunlight.
