DALY BMS Li-ion 7S 24V 20A BMS Battery Management System for 18650 Battery Pack Balanced Charging Board

The DALY 24V 7S 20A BMS is a high-quality battery management system designed specifically for 7-series (7S) 24V Lithium-ion battery packs. Equipped with a balance wire and temperature sensor, it ensures safe, stable, and long-lasting performance for your lithium battery setups. Protect your investment with reliable overcharge, over-discharge, overcurrent, short-circuit, and temperature protection. This BMS is specifically designed for 7S 24V lithium-ion battery packs and cannot be used with LiFePO4, Li-Metal, or LTO batteries. Its primary function is to protect your battery pack while ensuring a longer cycle life. The built-in balance feature keeps all cells at equal voltage, preventing early cell degradation.

Key Features

• Overcharge protection – stops charging when cell voltage reaches 4.25V
• Over-discharge protection – prevents battery discharge below 3V per cell
• Overcurrent protection – safeguards against excessive current flow
• Short-circuit protection – shuts down the battery instantly during a fault
• Temperature protection – prevents battery operation above 70℃ and below -20℃
• Balance function – maintains all cells at equal voltage for longer battery life
• High-quality MOSFETs and imported ICs for reliable performance

Protection Features

Overcharge and Over-Discharge Protection

The BMS stops charging once any cell reaches 4.25V and prevents discharge when voltage drops to 3V, ensuring safe operation and extending battery life.

Temperature Protection

The BMS provides protection at extreme temperatures: it prevents discharge above 70℃ and safeguards the battery from cold temperatures down to -20℃.

Short-Circuit Protection

In the event of a short circuit or circuit damage, the BMS will immediately shut down the battery pack to prevent damage and ensure safety.
