Battery Charger (Double)

Double Battery Charger Module is a charging circuit designed to charge two rechargeable lithium-ion batteries, typically 3.7V cells, either individually or as a two-cell battery arrangement depending on the module design. It manages the charging process and helps provide controlled charging, overcharge protection, and charging-status indication. It is commonly used in robotics, portable electronics, IoT devices, power banks, and battery-powered STEAM projects where two lithium batteries are required.
