3S 4A Type-C Li-ion Battery Charger Module – DC 3-5V to 12.6V Boost Charging Board

Charge 12V Battery with Mobile Charger

• Are you tired of buying expensive 12.6V adapters for your 3S battery packs? This Type-C USB Boost Charging Board is the solution.
• This smart module allows you to charge a 3-Series (3S) Lithium-ion Battery Pack directly from a standard 5V Phone Charger or Power Bank. It has a built-in step-up (boost) circuit that converts 3-5V input into 12.6V output.

Why is this Module Special?

1. Type-C Input Convenience: No need for special cables. Just use your Android phone’s Type-C cable to charge your DIY projects.
2. Built-in Boost Feature: It automatically boosts low voltage (DC 3-6V) to the required 12.6V for charging 3S batteries.

3. Safety Protection (BMS): This is not just a charger; it is also a protection board. It protects your battery from:

• Over-Charging
• Over-Discharging
• Short Circuits

4. Compact Size: It is very small and fits easily inside portable speakers, DIY toys, and LED light projects.
