4S 100A LiFePO4 Lithium Battery Protection Balance Charging BMS Protection PCB Board
[Lithium Battery Protection Board] ⚡ 4S 100A LiFePO₄ BMS Protection Board with Cell Balancing (White PCB) 4S LiFePO₄ Battery Management System • 100A Protection • Active Cell Balancing • Temperature Protection The 4S 100A LiFePO₄ Battery Management System (BMS) Protection Board is a high-performance protection circuit designed specifically for 4-cell (4S) 12.8V LiFePO₄ battery packs. It provides comprehensive protection against overcharging, over-discharging, over-current, short circuits, and temperature abnormalities, ensuring safe and reliable battery operation. Equipped with 15 ultra-low resistance MOSFETs and an integrated cell balancing function, the BMS helps maintain equal voltage across all four battery cells, improving battery efficiency, performance, and service life. The onboard balancing circuit automatically equalizes cell voltages during charging, reducing cell imbalance and maximizing battery capacity. This BMS supports both common port (same port) and separate charge/discharge (different port) configurations. In common-port mode, it supports up to 60A continuous charge and discharge, while in separate-port mode it supports 80A continuous discharge and 60A charging. The board also includes a temperature sensor interface for additional safety. Designed exclusively for 4S LiFePO₄ (3.2V) battery packs, this protection board is not compatible with 3.7V Li-ion, Lithium Polymer (Li-Po), or ternary lithium batteries. ⭐ Features Designed specifically for 4S LiFePO₄ battery packs High-current 100A protection design Built-in automatic cell balancing Over-charge protection Over-discharge protection Over-current protection Short-circuit protection Temperature protection interface Ultra-low resistance MOSFET design Supports common-port and separate-port wiring Low power consumption Easy installation and wiring Improves battery safety and lifespan 📋 Technical Specifications Product Type: LiFePO₄ Battery Management System (BMS) Battery Configuration: 4S (4 Cells) Battery Chemistry: LiFePO₄ (3.2V Cells Only) Maximum Protection Current: 100A Continuous Discharge Current (Separate Port): 80A Continuous Discharge Current (Common Port): 60A Maximum Charging Current: 60A Balancing Function: Yes Balance Current: 50mA Balance Voltage Accuracy: 3.355V–3.455V Overcharge Protection Voltage (Per Cell): 3.61V–3.69V Overcharge Recovery Voltage: 3.50V–3.60V Overcharge Detection Delay: 1.5–2.5 Seconds Over-discharge Protection Voltage (Per Cell): 2.27V–2.43V Over-discharge Recovery Voltage: 2.45V–2.65V Over-discharge Detection Delay: 0.5–1.5 Seconds Short-Circuit Protection: Yes Short-Circuit Detection Delay: 100–600µs Short-Circuit Recovery: Disconnect Load Temperature Protection: Yes (Temperature Sensor Interface) MOSFET Configuration: 15 Ultra-Low Resistance MOSFETs 🔧 Applications Suitable for: 12.8V LiFePO₄ Battery Packs Solar Energy Storage Systems Portable Power Stations Electric Scooters Electric Bicycles Backup Power Systems UPS Battery Packs Marine Battery Systems Caravan & RV Power Systems DIY LiFePO₄ Battery Packs Robotics Projects Industrial Battery Systems Battery Repair & Maintenance 📦 Package Includes 1 × 4S 100A LiFePO₄ Battery Management System (BMS) Protection Board – White PCB ⚠️ Note Compatible only with 4S (12.8V) LiFePO₄ battery packs.

Out of stockDHT11 Temperature And Humidity Sensor Module – for Arduino Raspberry STM (DHT11 with PCB)
[Temperature Sensor] Description DHT11 is a Humidity and Temperature Sensor, which generates calibrated digital output. DHT11 can be interface with any microcontroller like Arduino, Raspberry Pi, etc., and get instantaneous results. DHT11 is a low-cost humidity and temperature sensor which provides high reliability and long-term stability. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air and outputs a digital signal on the data pin (no analog input pins needed). Its very simple to use, and libraries and sample codes are available for Arduino and Raspberry Pi. This module makes it easy to connect the DHT11 sensor to an Arduino or microcontroller as includes the pull-up resistor required to use the sensor. Only three connections are required to be made to use the sensor – Vcc, Gnd, and Output. It has high reliability and excellent long-term stability, thanks to the exclusive digital signal acquisition technique and temperature & humidity sensing technology. Specifications:- Power Supply： 3.3~5.5V DC Output： 4 pin single row Measurement Range： Humidity 20-90%RH， Temperature 0~50℃ Accuracy： Humidity +-5%RH， Temperature +-2℃ Resolution： Humidity 1%RH， Temperature 1℃ Interchangeability： Fully Interchangeable Long-Term Stability： <±1%RH/year Pin Description:- Pin 1: Power +Ve (3.3VDC to 5.5VDC Max wrt. GND) Pin 2: Serial Data Output Pin 3: Power Ground or Power –Ve * Product Images are shown for illustrative purposes only and may differ from actual product.
