The 7S 24V 10A Battery Protection Board (BMS) is a critical component for managing 7-series lithium-ion battery packs, providing essential safety features like overcharge, over-discharge, and short-circuit protection. These boards typically support a continuous discharge current of 10A, making them suitable for moderate-power applications like electric bikes, scooters, and small solar storage systems. Key Specifications and Features:Voltage Management: Supports a nominal voltage of 24V–25.9V and a maximum charge voltage of 29.4V.Protection Thresholds:Overcharge Protection: Kicks in at approximately 4.25V ± 0.025V per cell.Over-discharge Protection: Activates at roughly 2.7V to 2.8V per cell.Balancing Function: Includes an integrated equalizer that distributes charge evenly across all 7 cells, typically with a balancing current of 40mA to 80mA.Temperature Protection: Many models feature NTC thermal monitoring, often cutting off at 50°C for charging and 70°C for discharging.Physical Design: Often features an aluminum heat sink for better thermal dissipation and a compact footprint (approx. 108 x 34 x 2.8mm).Common Applications:Electric Mobility: Ideal for e-bikes, electric scooters, and wheelchairs.Renewable Energy: Used in solar street lamps and small-scale energy storage systems.Power Tools: Suitable for cordless tools that operate on a 24V system.
