Lithium / LiFePO4 Battery Charger, Supports 1-3 Cells in Series
€6.50
Tax included
Complete CC/CV linear charger for Lithium-ion or LiFePO4 batteries, supporting 1 to 3 cells in series. Wide input 7.5-28V with solar MPPT tracking and 5A max current.
This module is a complete constant-current/constant-voltage linear charger for Lithium-ion or LiFePO4 batteries, supporting configurations from 1 to 3 cells in series. It features a wide input voltage range (7.5V to 28V) compatible with standard chargers or solar panels via MPPT tracking.
Specifications
- Input Voltage: 7.5V to 28V (must be +2V higher than battery voltage).
- Maximum Charge Current: 5A.
- Supported Chemistry: Lithium-ion (Li+) and LiFePO4.
- Charging Profile: 3-stage (trickle, constant-current, constant-voltage).
- Status LEDs: Charging in progress and charging complete.
- Adjustable cut-off voltage via feedback resistor divider (Rvfb).
