Phantom 4 Multi-Battery Charging Hub

This Ultimaxx hub connects to the DJI Phantom 4 Battery Charger and manages up to three Intelligent Flight Batteries. It is built for Phantom 4 pilots who want to line up several packs for overnight charging without swapping cables. The unit only works with the Phantom 4 battery series and the original charger sold separately.

Sequential Charging With Storage Mode

The hub reads each battery’s level and feeds power to the fullest pack first, moving down the line automatically. A dedicated Storage Mode holds every connected battery at 50 charge, keeping cells above the minimum safe voltage during long breaks between flights. No manual reordering or monitoring is required once the session starts.

Plug-In Setup And Common Issues

Installation is a simple matter of seating the hub on the Phantom 4 charger and clicking each battery into its slot. The most frequent problem occurs when a deeply discharged pack fails to wake up, causing the sequence to stall on that slot. Users also report intermittent contact if the battery terminals are not fully latched, so a firm press on each pack is advised.

Questions about this item

How do I keep the Phantom 4 batteries healthy during long periods of non-use?

The hub offers a Storage Mode that maintains each Phantom 4 Intelligent Flight Battery at a 50% charge level, keeping voltage above the minimum safe threshold until the next flight.

Which battery will finish charging first when three are connected?

The hub sequences charging by current power level, so the battery holding the most charge reaches full capacity before the others begin.

Does the hub itself draw extra power or generate noticeable heat while charging three batteries in a row?

The hub passes power from the separate Phantom 4 Battery Charger to one battery at a time, so its own power draw and heat output remain minimal during extended charging sessions.
