Product Description

The DALY 20S 72V 30A BMS is a high-performance Battery Management System designed specifically for 20 series 72V Lithium-ion battery packs. Built with high-quality MOSFETs and imported ICs, this BMS ensures maximum safety, reliability, and extended battery life. It offers essential protection features such as overcharge, over-discharge, overcurrent, short circuit, and temperature protection, making it ideal for high-demand applications.

Configuration

Designed for 20S Lithium-ion battery packs (72V). This is a fixed configuration and is not compatible with LiFePO4, Li-Metal, or LTO batteries. Supports popular lithium cells such as 18650, 21700, 36500 cylindrical cells, and prismatic cells. Purpose-built for Lithium-ion chemistry only.

Protection Features

  • Overcharge & Over-discharge Protection: Automatically stops charging at 4.25V/cell and discharging at 3V/cell.
  • Temperature Protection: Safeguards batteries from extreme temperatures (discharge cut-off around 70℃ and low-temp protection down to -20℃).
  • Short Circuit Protection: Instantly shuts down the battery in case of circuit failure or damage.
  • Overcurrent Protection: Prevents damage caused by high load or excessive current flow.

Certifications Approved

ISO / FCC / RoHS / PSE / CE certified.

Applications

  • Solar energy storage systems
  • Electric bikes (E-bikes) & scooters
  • Electric skateboards & hoverboards
  • Camping boats & RVs
  • Power tools
  • Lawn mowers & household energy storage

What's Included in Package?

  • DALY 20S 72V 30A Li-ion BMS.
  • Balanced wire sense cable (17-wire with connector).
  • User manual & installation guide.

Advantages

  • Uses Seiko IC (Japan) with power balancing for high reliability and a simplified, robust circuit.
  • Strong load capacity – constant discharge current up to 30A with high-voltage, low-resistance MOSFETs and a heat sink for cooling.
  • Ultra-low power consumption (<50μA) to maximize standby battery life.
  • PCB with anti-corrosion, water-resistant, and ESD-resistant conformal coating.
