Ultra Power UP4000-24S 4000W 25A 16-24S LiPo/LiHV Charger

The Ultra Power UP4000-24S is a dual-channel 4000 W charger for 16–24S LiPo, LiHV and intelligent batteries, the high-voltage packs used on large agricultural spray drones and heavy-lift industrial UAVs. It runs from AC 100–240 V mains and charges through AS150U outputs.

Key features

• 4000 W total across two independent channels, so two high-voltage packs charge at the same time.

• Charge current selectable at 5, 10, 15, 20 or 25 A.

• LiHV charging up to 4.45 V per cell, alongside standard LiPo.

• Balance current up to 2 A per cell keeps long series strings even.

• Balance and storage modes with automatic stop; 400 W (2 × 200 W) discharge for storage.

• 3.2-inch colour screen, three ball-bearing cooling fans and over-voltage, reverse-polarity, short-circuit and over-heat protection.

Running both channels at full output draws more than 17 A from 230 V mains, beyond a standard 16 A socket, so use a dedicated circuit or a generator sized for the load. Packs with other main leads need an AS150U adaptor.
