7S 50A 24V Lithium-Ion Battery BMS Protection Board – Balance Protection Circuit Module for E-Bike & Power Tool Packs in Pakistan

Overview

When building or restoring high-drain 7-series (7S) lithium-ion battery packs—such as 24V e-bike batteries, cordless lawn mowers, DIY power tool replacements, or large portable energy reserves—cells can easily become unbalanced or suffer catastrophic damage from overcharging, deep discharge, or short circuits. Operating without intelligent oversight puts your expensive battery investment at risk. The 7S 50A BMS Protection Board provides a robust, high-current battery management solution, engineered to balance cell voltages and shield your pack from electrical hazards under demanding loads.

Key Features

• Tailored for 7S Lithium-Ion Packs: Configured specifically for 7-string 24V nominal (29.4V fully charged) lithium-ion battery configurations.

• Heavy-Duty 50A Continuous Current: Designed to handle high-drain motors and heavy inverters without triggering thermal shutdowns or failing prematurely.

• Integrated Cell Balancing: Built-in equalization circuitry ensures all 7 individual cell groups charge evenly, maximizing overall pack lifespan and capacity.

• Comprehensive Multi-Protection Circuitry: Actively guards against over-charge, over-discharge, short-circuit, and excessive current discharge events.

• Low Resistance MOS Switches: Utilizes quality power MOSFETs to ensure minimal voltage drop and efficient heat dissipation during high-output operations.

Technical Specifications

Common Applications

• 24V E-Bike & Scooter Packs: Essential safety core for rebuilding or building custom high-drain mobility battery packs.

• Cordless Power Tool Rigs: Protects heavy-duty drill and garden tool battery packs against sudden overloads and cell degradation.

Note to customers: Always connect the balance wires in exact numerical order (from B- to B1, B2, up to B7+) before plugging into the BMS to prevent board damage!
