I like the charger construction and the project idea, however the product is still an ‘under development’ item.
there are some software glitches, in controlling apps (and probably inside the firmware).
I suggest to buy also the external controller to better use the charger.
The XT60 output connector have 3 pins, i.e. it have the connector used for BATTGO protocol.
However currently BATTGO batteries are not recognized.
I cannot find the way to connect via RS485
nor CANBUS, as documented in official ISDT product page.
The charger is not well documented.
