Ultra PowerUltraPower - UP4000 - 14S - 4000W 40A AC Charger

The UP4000-14S is a professional-grade battery charger engineered for large LiPo and LiHV battery systems (6S–14S). Designed to meet the needs of UAV operators, agricultural drone users, and surveying professionals, it delivers high power, reliability, and dual-channel flexibility for maximum efficiency.

With simultaneous dual-channel operation, the UP4000-14S allows you to charge or store two large battery packs at once, minimizing downtime and optimizing workflow productivity. Its full-range AC input (100–240 V) ensures global compatibility, making it perfect for field and workshop use across different regions.

Built to deliver up to 4,000 W in optimal dual-channel operation, this charger can handle large-capacity battery packs with ease, providing rapid and balanced charging performance.

User convenience is a priority — the independent channels support multiple modes including Charge, Storage, and Charge-Hub, ensuring optimal battery conditioning and extending battery lifespan.

The UP4000-14S also emphasizes safety and reliability, integrating multiple protections such as over-voltage, over-current, reverse polarity, and over-temperature safeguards. Its efficient cooling system and heavy-duty construction make it ideal for demanding or semi-industrial applications.
