Voltage Platform & Load Class — Where This BMS Fits
📊 20S (60V) — Heavy-Load EV Applications
The 20S platform at 60V covers electric motorcycles, forklifts, and heavy sightseeing vehicles in the heavy-load category (150–200A). The HC version adds inverter CAN communication and heating protection — for cold-climate deployments or applications requiring BMS-to-inverter integration.
🔌 CAN + UART — Inverter Integration & Display Support
CAN bus enables direct BMS-to-inverter communication. UART connects to LCD displays for local panel monitoring. For RS485/SCADA integration or hard parallel expansion, see the HCR version.
🔥 Heating Film Control — Cold-Climate Protection
Built-in heating film control port activates the heating film when cell temperature drops below the configured threshold — essential for vehicles and equipment operating in cold climates or unheated facilities.
📦 Soft Parallel via PLINK Module
Supports soft parallel expansion via the optional PLINK Module (sold separately). Hard parallel via Parallel Module is not supported on the HC version.
Who Is This BMS For?
- 🏍️ Electric motorcycles (48V–60V, heavy-load)
- 🚜 Forklifts & industrial vehicles in cold-climate environments
- 🛴 Heavy sightseeing vehicles with inverter integration
- 🚗 Light electric cars requiring CAN BMS communication
- 🏭 OEM manufacturers of 24V–60V 200A battery packs with heating
