VOTOL EM25P is an entry-level 48V/60V sinewave controller with 25A rated DC current, suited for 1000-1200W PMSM/BLDC motors in small e-scooter / e-bike builds. 'P' variant is LIN-only with no CAN BUS support and no anti-theft system — the cheapest tier in VOTOL's EM-series. Features flux weakening, IP65 waterproofing, programmable via PC. Uses a simplified subset of VOTOL's 'Old Version' EM/SV-series connector architecture: 2 flush Mini-Fit Jr headers (function 2×8 + hall 2×3) + screw terminals for power/phase. No alarm/anti-theft port.

In brief: 48–72V controller. 25A continuous. 40A peak. Sinewave, sensored, regen, field weakening support.
