DFRobot DFR0667 Lipo Charger is designed for a single-cell 3.7V lithium battery. This charger adopts a TP4056X lithium battery charging IC that guarantees quick and safe charging. The Lipo Charger features an external indicator for checking the charging status when the module is integrated into any project. This charger offers three output current modes that can be easily switched by selecting different bonding pads on the backside. The thermal feedback inside the TP4056X can automatically adjust the charging current to limit the chip temperature under high power operation or high ambient temperature conditions.
