16.8V 20A Li-ion Battery Charger for 4S 14.8V Battery
To support high-capacity automated heavy machinery and intensive material handling grids, the Phonix® FX16820000 delivers an exceptional 336W output matrix as a heavy-duty 16.8V 20A Li-ion battery charger. Purpose-built to sustain rapid energy turnover for high-capacity 4S 14.8V battery networks, AGV robotics, and localized storage banks, this solid-state fanless system eliminates peak-charging thermal lag through strict localized constant-current management. The reinforced metal-hybrid chassis (233*108*64 mm, 1900g) integrates oversized internal conductive paths for passive ambient air cooling, completely sealing active logic architectures from severe factory grime, ferrous fragments, or airborne oil mists. Regulated by an enterprise-tier MCU safety core, it deploys autonomous latch lockouts against sudden infrastructure load shifts, covering over-voltage, short-circuits, and phase cross-connections. Engineered for zero-downtime mission-critical networks with a 100,000-hour MTBF and a 3-year factory warranty, this 20A charging platform easily complies with the most stringent institutional procurement specifications via full regulatory stamps (UL, CE, TUV, FCC, PSE, CCC).
Description
High-Amp Fleet Maximization via Solid-State Convection Thermal Design
Sustaining a continuous 336W electrical envelope without relying on failure-prone internal mechanical fans requires dedicated internal thermal topology. The Phonix® FX16820000 integrates an expanded, heavy-duty flame-retardant chassis (233X108X64 mm, weighing 1900g) built around solid-state passive air dissipation pathways. For high-drain mobile robotics and enterprise security backup infrastructures, eliminating fans means zero vulnerability to conductive soot, metallic dust, or moisture ingress that routinely shorts standard commercial chargers. The aluminum-alloy enhanced housing keeps case temperature rise restricted to < 40°C under maximum constant-current stress, ensuring long-term fleet uptime while preventing thermal throttling during repetitive bulk-charge sequences.
