SIAECOSYS DKD LCD
SIAECOSYS DKD LCD segment-LCD speedometer designed for VOTOL controllers (per OEM product page). Dual-protocol support — CAN BUS or ONE-LIN (auto-detect on power-up), firmware-selectable. Also paired with Fardriver controllers sourced through SIAECOSYS in some kit bundles. Shows speed (KMH/MPH), battery voltage, gear/mode (DNR / 1-2-3-S), ×10A current, odometer, trip meter, and fault codes. Configurable 48V / 60V / 72V / 96V pack presets via password 856. Compatible across VOTOL's full EM and SV series. ⚠️ **Power-supply warning:** the black (+12V) wire is an auxiliary supply input — it must be fed from a 12V DC-DC converter or the 12V aux output of a smart BMS, NOT pack B+. Connecting the black wire directly to pack voltage (48V / 60V / 72V / 96V) will destroy the display instantly. The voltage presets set the pack voltage the display measures on its sense line — not the supply input. Designed for electric scooters, e-motorcycles, and e-mopeds.
In brief: E-bike display. Protocols: SiAECOSYS ONE-LIN, SiAECOSYS CAN BUS.
