Type C BMS 2S 2A Step-Up Boost Li-Po Polymer Charger Module,
120.00৳ 150.00৳ (-20%)
The Type C BMS 2S 2A is a compact step-up (boost) charger module that converts a standard 5V USB-C input into an 8.4V output to charge two lithium batteries (18650/21700) connected in series.
Quick Specs
- Input: USB Type-C (DC 3V–6V; 5V recommended).
- Output: 8.4V (specifically for 2S battery packs).
- Charging Current: 2A.
- Status Lights: Onboard LEDs indicate “Charging” (CR) and “Full/Standby” (OK).
- Protection: Includes over-voltage, short-circuit, and battery-leakage protection.
This module is ideal for DIY power banks or upgrading older 7.4V electronics to modern USB-C charging.

Type C BMS 2S 2A Step-Up Boost Li-Po Polymer Charger Module,
This module is a compact Step-Up (Boost) Charging Board designed to charge two series lithium batteries (2S) using a standard USB Type-C input. It is commonly used in DIY power banks, portable electronics, and small robotics projects.
Core Specifications
- Charging Configuration: 2S (Two batteries in series, nominal 7.4V).
- Input Port: USB Type-C.
- Input Voltage: DC 3V to 6V (Works perfectly with a standard 5V phone charger).
- Output Voltage: Boosted to 8.4V (the full charge voltage for a 2S pack).
- Max Charging Current: 2A (fast charging for this size).
- Dimensions: Roughly 3.7cm x 1.7cm (very small footprint).
Functional Highlights
- Automatic Charging: It manages the constant-current/constant-voltage (CC/CV) charging cycle required for lithium batteries.
- Status Indicators: It features onboard LEDs (marked OK and CR) to indicate charging status (e.g., Red for charging, Green/Blue for fully charged).
- Built-in Protections:
- Over-voltage protection for the battery.
- Short-circuit protection at the battery terminals.
- Power adaptability, meaning it can adjust its draw if your input power source is weak.
Connection Guide
- VIN / GND (Left): These are alternative solder points for your 5V input if you don’t want to use the USB-C port.
- BAT / GND (Right): Connect your 2S battery pack here. Note: This board boosts voltage but does not always include individual cell balancing; ensure your battery pack has its own protection circuit (BMS) for safety.
