High-Current 18650 Lithium Battery Protection Board with Balancing for Power Tools
Premium 40A continuous discharge current ensures stable power delivery for high-demand applications like electric drills, DIY tools, and RC models. Advanced multi-layer PCB design with reinforced copper traces prevents overheating and voltage drops, extending battery lifespan. Built-in precision balancing circuit maintains uniform cell voltage (14.8V/16.8V), critical for maximizing pack efficiency and safety. Industrial-grade MOSFETs and anti-spark protection enable instant tool startup without voltage spikes, ideal for professional workshops. Compact anodized aluminum casing dissipates heat rapidly while resisting corrosion in humid environments. Seamless compatibility with 4S 18650 battery configurations—perfect for upgrading cordless equipment or custom power solutions. Universal screw terminals allow tool-free installation, saving time for bulk purchasers and resellers. Certified CE/RoHS compliant—meets strict EU safety standards for wholesale distribution.
