Fox ESS HV BMS-V2 battery management module
Fox ESS pairs its high-voltage batteries with a separate controller, and the HV BMS-V2 is the second revision of that module, aimed at installers putting new Fox HV storage on the quote. Where the battery series in a design calls for V2 control, this is the part number to spec from the start.
Delivery in 3–5 working days (estimate). The dispatch clock starts at cleared payment.
Description
Fox runs two revisions of its HV control module, and ordering the wrong one stalls a commissioning visit. Matching the V2 to the battery series that calls for it at the point of quoting removes that failure before the van leaves the yard. For firms fitting current Fox HV battery stock, standardising on the V2 keeps procurement simple: one controller part number across new jobs. Pricing is flat here, so a one-off controller for tomorrow's job costs the same per unit as a batch for the racking.

What it pairs with
Partner it with Fox ESS HV battery packs from the ECS and EP ranges listed on this site, with the Fox HV junction box where a design parallels multiple batteries, and with Fox H1 or KH1 hybrid inverters. BMS revision requirements vary by battery series and version, so check the current Fox ESS pairing and stacking list before ordering.
A controller only, with no storage capacity or output of its own; battery modules are bought separately. Fox lists the original BMS alongside this V2, so confirm which revision your battery series specifies. For anything this page can't settle, ask the trade desk before ordering or consult a competent installer.
