The 12.6V 2A Lithium Battery Charger is a precision CC/CV (Constant Current / Constant Voltage) smart charger from KSPOWER’s LiFePO4 & Lithium-ion Chargers series — purpose-built for 3S Li-ion / Li-Polymer battery packs (three 4.2V cells in series, 12.6V full charge voltage). It delivers a safe, complete charging cycle with automatic CC-to-CV transition, protecting cell health and maximizing cycle life.
Designed for global markets, the charger is certified to UL, CE, KC, PSE, SAA and UKCA safety standards — with universal AC input 100-240VAC covering every major market with a single SKU. The fully enclosed plastic case is available in three mounting styles — wall plug, desktop or open lead wire — so integrators can choose the exact form factor for their application.
CC/CV Smart Charging Profile
The charger implements a two-stage constant current / constant voltage (CC/CV) charging algorithm — the industry-standard safe charging profile for lithium batteries:
| Stage | What Happens | Battery State | LED |
| Stage 1 — CC (Constant Current) | Charger delivers constant 2.0A current; voltage rises gradually toward 12.6V | 0% – 80% charge (bulk charge) | Red LED ON |
| Stage 2 — CV (Constant Voltage) | Voltage holds at 12.6V; current tapers down automatically as battery approaches full | 80% – 100% charge (absorption) | Red LED ON |
| Stage 3 — Charge Complete | Current drops below termination threshold; charging stops automatically | 100% full | Green LED ON |
This precision profile prevents over-charging (lithium plating), over-voltage stress and electrolyte degradation — protecting your battery investment and extending pack cycle life. ±0.5% voltage accuracy ensures a true full charge without cell damage.
