I own it for over a month:

1. it has manual mode (for pro users only) it can give live voltage on DC (CCS) terminals so its possible to use it like on board charger if you have direct access to battery terminals (200-750V range)
2. fans spinning speed seems to be depend only of what DC current is adjusted (not about temperature) bcoz if I adjust it from 25 to 50A its spinning faster instantly
3. you can adjust current only before charge starts (energica e-moto has current adjustable in bike menu so that why I can run test about fan speeds in point "2"
4. charger at full power (50A) its very loud, every seller tells noise is accepteable but its really dont, its impossible to stay in garage at 50A for longer period of time, or making converstations
5. its detect max voltage and current of vehicle BMS and show it on menu (for example - energica max is 75A and it shows 75A, tesla 3 shows 599A, about voltage it show a little higher than cells can do - in tesla its hows 423V (403V is 4,2V on cell)and on energica (80S so 336v max it show 363V)

for sure I want to modify it in future to make possibiluty of adjsust current in real time by dial (I think it will be possible to add potentiometer between PP terminal in CCS plug but will see

Very interesting.. now if I could find something to go the other way as my conversion will likely be AC only (sub 200 volt).

I'm curious which power supply module they use.

charger module range is 150-750V, maybe minimum is 150V but I dont know, if you really want to know I can check it for you

what voltage and capacity of battery you want to use? for about 250-300$ they offered me custom voltage (max 3kW charger which is IP65)

I'm curious which power supply module they use.

I don't know the cell voltage but I think we are looking at only 20-22KW total.
My concern is not speed but simply if I cake a trip not being able to find a Type 2 charger close to my route.
Almost are are CCS only...
