The Ultimate All-in-One Power Solution for Makers
Are you looking to upgrade your electronics projects with rechargeable power? The LX-LBC3 Type-C Charging & Discharging Module is engineered to replace bulky, outdated charging boards. Measuring just 16mm x 12mm, this component is smaller than the cross-section of an 18650 battery, yet it packs a punch with intelligent power management.
Why Choose the LX-LBC3?
Unlike standard linear chargers, this module handles both input (charging) and output (discharging) through the same port or solder pads. It effectively manages 3.7V Lithium-ion or Lithium-polymer batteries, boosting their voltage to a stable 5V output for your devices.
Superior Efficiency & Safety
Say goodbye to overheating. This module offers better thermal control than the traditional 4056/4057 chipsets. It comes equipped with built-in protection against over-charging and over-discharging, ensuring your DIY projects remain safe and your batteries last longer.
Versatile Applications:
- DIY Power Banks: Create emergency backup power for low-current devices.
- Retrofitting: Convert AA-battery powered toys or gadgets to rechargeable Lithium power.
- Repair: Fix broken charging ports on tablets or Bluetooth speakers.

FAQ Section
FAQ Section
Q: Can I use this module to charge my iPhone or flagship Android phone?
A: This module is designed for low-power DIY applications (approx. 450mA output). While it outputs 5V, it does not support fast-charging protocols (PD/QC) and may charge modern smartphones very slowly or not at all. It is best suited for fans, LEDs, Arduino projects, or Bluetooth accessories.
Q: Can I connect multiple batteries to this board?
A: You can connect multiple 3.7V batteries in parallel to increase capacity (mAh). However, you must NEVER connect batteries in series (e.g., to make 7.4V), as this will instantly damage the board.
Q: Does it support "Pass-through" charging (UPS mode)?
A: The module supports automatic switching. If external power is connected, it charges the battery. If power is removed, it switches to battery output. However, there may be a micro-second delay during switching, so sensitive microcontrollers might reset without a buffer capacitor.
