25.2V 3A Li-ion Charger for 6S 22.2V Battery
Phonix® FX2523000 is an infrastructure-grade 25.2V 3A (75.6W) smart fast charger engineered for 6S 22.2V Li-ion/Li-Po industrial battery packs. Housed in a sealed, fanless 133X58X36mm enclosure, it blocks airborne shop floor contaminants while maintaining ≥85.0% efficiency via natural convection. Powered by a hardware MCU control loop with a multi-stage charging profile, a certified 50,000-hour MTBF, and our 5-year factory warranty, this silent module delivers stable, zero-maintenance terminal power matching for commercial drone fleets, field electronics, and automated testing rigs.
Description
Precision Ripple Mitigation and Dynamic Electrochemical Impedance Alignment
Supplying a continuous 75.6W output into 6S lithium cell architectures requires stringent mitigation of high-frequency switching noise to avoid localized cell degradation. The Phonix® FX2523000 solves this through an integrated multi-stage Pi-filter matrix that suppresses output ripple voltage to ≤168mV under absolute full load conditions. By lowering transient noise, the internal MCU closed-loop system accurately tracks the battery pack’s internal dynamic resistance without deceptive voltage false-triggers. Rejecting mechanical cooling fans, the 133X58X36mm chassis utilizes specialized solid-state thermal pads to dissipate energy through its rugged, non-ventilated polymer outer shell. This complete enclosure keeps the internal multi-layer PCB permanently clear of conductive dust, workshop soot, and atmospheric humidity sags, isolating sensitive control logic and keeping shell temperature rise under < 40°C across extended constant-current cycles.
