Four batteries
Both charge managers support the insertion of four batteries at a time, and then charge in order of the remaining power from most to least, the purpose is to fill the first battery as quickly as possible.
The charging Butler allows you to plug in all the batteries at the end of the day and go to rest without having to replace them halfway through. There are two main differences between the premium and regular versions. One is that the premium version supports both the Phantom 4's 100W charger and car charger, while the regular version only supports the Mavic's built-in 50W charger and car charger.
Secondly, the advanced version can be pipelinized during the charging process, that is, when the previous battery enters the constant voltage charging of the rear section, the front section of the next battery can be opened for constant current charging, which makes full use of the power of the power adapter to provide faster charging speed.

In normal mode, the battery management station can charge up to eight TB50 batteries simultaneously. If the voltage difference between the two batteries in the vertical direction is large, the low-voltage battery will be charged first and charged at the same time when the voltage is close.
In fast mode, the battery management station can charge up to two groups of batteries at the same time, preferentially charging the battery to 90%, after charging to 90%, it is considered that the battery has carried enough power. If both sets of batteries placed in the vertical direction are 90% full, and the battery is not pulled out, it will continue to recharge to 100%
DJI battery manager is a DJI drone battery charger, which can continuously charge four batteries, and the battery manager will take turns to charge the battery, which needs to charge the four batteries separately.
