WATTNINE 11V 2A Lithium Battery Charger with CC/CV and Charge indication for 3S LFP Li-ion Battery pack

The WATTNINE 11.1V 2A Wall Mount 3S LFP Lithium Battery Charger with CC/CV is a reliable and efficient charger designed specifically for 3-cell (3S) LiFePO₄ (LFP) battery packs. It uses Constant Current / Constant Voltage charging, which initially supplies a fixed current and then maintains a stable voltage to safely complete the charging process. This ensures efficient charging, extended battery life, and protection against overcharge and overcurrent. Integrated charge status indication allows easy monitoring of the charging state.

Features:

1. High-quality construction for long-lasting reliability
2. Constant Current / Constant Voltage (CC/CV) charging
3. Charging status LED indication
4. Short Circuit, Over Voltage & Over Current Protection
5. No minimum load required
6. Compact and lightweight design for easy installation
7. Regulated stable voltage output
8. Low ripple and interference for sensitive electronics
