Product Description
The 2S 20A 18650 Lithium Battery Protection Board serves as the dedicated controller for your 7.4V battery assemblies. It utilizes a high-accuracy voltage detection circuit to monitor each cell individually. If a cell reaches its full capacity or drops to a dangerous voltage level, the module instantly cuts the power supply to prevent damage. This module is designed for a service life of over 30,000 hours, making it a reliable choice for long-term industrial or hobbyist installations.
Equipped with high-efficiency MOSFETs, the board manages a continuous discharge current of up to 13A, with a peak surge capability of 20A. This makes it suitable for inductive loads like high-torque DC motors that draw significant current during startup. The compact form factor allows it to be tucked neatly inside a 3D-printed battery case or shrink-wrapped directly onto an 18650 pair.
Key Features
High-Current Handling: Supports a continuous 13A discharge and up to 20A peak, ideal for power tools and robotics.
Integrated Protection IC: Hardware-level sensing for over-charge, over-discharge, and short-circuit protection.
Automatic Reset: Restores operation once safe voltage levels are reapplied or the fault condition is removed.
Compact PCB Footprint: Measuring approximately 45mm x 19mm, it is easy to integrate into slim battery enclosures.
Low Standby Drain: Consumes less than 10µA, preventing the battery from self-discharging during storage.
