More specifically this thing: HCX-D170V1 from bestech.
Does it need a CC/CV charger?

battery specs:

22s24p
92.4v and 480amps
3000mah per cell
Type 18650 cells
Max discharge 20A per cell

What charger or PSU or converter you want to use is not usually dictated by the BMS, nor v/v

unless you want the BMS to do the primary charge control, which IMO is usually not a great idea.
