CD42 Lithium Battery Boost & Charge Module – 5V 2A (Based on IP5306)

CD42 5V 2A Lithium Battery Boost Module (3.7V / 4.2V) – With Charge & Discharge Protection

Power your portable projects with confidence using the CD42 5V 2A Boost Module  a compact yet powerful solution designed to safely manage both charging and discharging of lithium batteries (3.7V / 4.2V). This module isn’t just about boosting voltage – it’s built with smart protection: over-voltage, over-current, and short circuit protection ensure safe operation. Ideal for DIY electronics, battery packs, or embedded systems, it delivers stable 5V output from a lithium cell with ease.

Four onboard LED indicators give you a clear view of battery status, and ultra-low standby current ensures efficiency when idle.
