Description
A rectangular smart board for managing and protecting 7.4 to 8.4 volt, 5 amp lithium batteries in series.
The Lithium Battery Protection Board (2S 5A BMS Protection Board) is an integrated and essential electronic protection system, specifically designed to manage, charge, and discharge a series array of two lithium cells (such as the popular 18650 or 21700 cells) connected in series with a standard rectangular design that provides a stable power line with a nominal voltage of 7.4V and up to 8.4V when fully charged, with a continuous operating current of 5 amps and a maximum overcurrent cut-off limit of 7 amps.
This board is considered the standard and economical Benchmark in building medium-voltage smart devices and systems; it provides integrated quadruple protection on a small, lightweight board to protect cells from: overcharge protection, over-discharge protection that damages cell chemistry, overcurrent protection above the safe limit, and extremely fast and immediate protection against short-circuit current. It is the professional and sole choice for building portable power packs, operating RC wireless aircraft, emergency light batteries, small line-following robots, and STEM and digital control projects for devices operating in the 8V voltage range.
A premium, highly compact 2S 5A Li-ion lithium battery BMS protection board precision-engineered to manage and safeguard a 2-cell (7.4V - 8.4V) lithium-ion battery pack configuration in a standard rectangular form factor. Standing as the definitive hardware benchmark for dual-cell portable electronics and hobbyist power supplies, this subassembly utilizes high-fidelity voltage monitoring ICs to shield the 18650/21700 cell grid against critical runtime faults. It fields a continuous operating current of 5A with a strict hardware current limit cutoff at 7A, delivering optimal defense against cell overcharging, destructive deep over-discharging, output overcurrent spikes, and sudden short-circuits. It serves as an essential, space-saving power management utility for RC airplanes, small autonomous robotics chassis, portable DIY test instruments, and introductory academic STEM electronics.
