Crocodile Alligator Clip 50 mm Black and Red
Description: An alligator clip, also called a spring clip, creates a temporary electrical connection using a simple mechanical design.It gets its name because the jaws resemble an alligator or crocodile’s mouth, opening and closing to grip objects securely.The clip works like a spring-loaded clothespin that uses tapered, serrated jaws to hold wires or metal parts tightly.A spring pushes the jaws together, allowing the clip to grip objects and maintain a reliable electrical connection.Manufacturers design these clips for electronics testing, enabling quick connections without soldering or permanent joints.One jaw usually connects to a wire by crimping or soldering for efficient current transfer.Some clips use a bent jaw forming the inner contact of a 15 mm to 4 mm female banana jack.This design allows a fast, non-permanent connection between test circuits and laboratory instruments.A plastic cover or boot surrounds the clip to prevent short circuits and protect users from accidental shocks.Engineers and students use these clips widely in testing, prototyping, and educational experiments. Applications: Technicians use small clips (15 mm–40 mm) in electrical laboratories, schools, and college labs for quick test connections.Large clips, called automotive clips or battery clamps, use solid copper for low resistance and strong current flow.Users connect these large clips with thick insulated copper cables between automobile batteries or heavy electrical systems.Hobbyists and professionals rely on these clips for safe, reusable, and efficient electrical connections. Product Example: Check the Crocodile Alligator Clip 50 mm – Red and Black, made from durable stainless steel with a protective plastic shroud.Its spring-loaded jaws open wide to grip different wire sizes securely during testing or circuit connection.The serrated teeth ensure a strong, slip-free grip that maintains stable electrical contact during operation.

[Sleeves] Description One of the best ways to seal your battery is by using heat shrink. It can protect your battery from short circuits, seal your battery against the weather and add a professional look to your DIY battery.PVC heat shrink is great for battery use, but it can sometimes become brittle over time and begin to crack at the edges or at sharp corners. One method around this is to use multiple layers. This strengthens the heat shrink and adds a second line of defence if one layer should begin to crack. It also allows you to use multiple pieces of heat shrink perpendicular to each other to cover all six sides of a battery instead of just four sides, thus completely sealing your battery. Adding a thin layer of foam around your battery can also help prevent the cracking of the heat shrink over time. 32mm PVC Heat Shrink Sleeve For Battery Pack Colour- Blue Radial Shrinkage- 9% – 21% Depending on the Size Material- Poly Vinyl Chloride Tensile Strength- Greater than or Equal to 4000 Pa/m2 Package Includes : 1 x 32mm PVC Heat Shrink Sleeve Blue for Lithium Cell Pack (1 Meter)

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.
