tsdz2b 250w with 48v

[old-tt-racer]

Hi all, first post and very new to this so please be gentle.

Would like to fit the latest tsdz2b with a 48v battery but limited to 250w to comply with uk regs, can only find enerprof doing one, so wondered why no one else did one ? Read some posts about locked firmware, but if enerprof do one why isn't anyone else ? Or am I missing something . Also anyone ordered from them before ?
Thanks for any advice given.

Enerprof sell the tdsz with the new B controller which can't be used with OSF.
