Full-Featured ESS & Parallel-Ready — JKBMS JK-B2A8S20P-HCRPB 200A Smart BMS for 3S–8S
The JK-B2A8S20P-HCRPB is the full-featured version of the 200A / 2A active balance platform — adding RS485, Buzzer Alert, and hard parallel interface on top of the HC version’s Heating, CAN, and UART. Designed for small home ESS, inverter-integrated systems, and multi-pack parallel installations that require complete communication and expansion capability.
Compatible chemistries: LiFePO4 / Li-ion / LTO

What the HCRPB Version Adds Over HC
📶 RS485 — SCADA & Multi-Device Integration
RS485 enables integration with SCADA systems, energy management platforms, and multi-device monitoring networks — essential for professional ESS installations and industrial applications.
🔔 Buzzer Alert — Audible Fault Notification
Built-in buzzer provides immediate audible alerts for fault conditions — over-voltage, under-voltage, over-temperature, and other protection events — without requiring external monitoring.
🔗 Hard Parallel Interface — Multi-Pack Expansion
Enhanced hard parallel interface supports connection of the optional Parallel Module (sold separately) for hardware-level multi-pack parallel operation. Also supports soft parallel via the optional PLINK Module (sold separately).
🔥 Heating Film Control — Low-Temperature Protection
Built-in heating film control port activates the heating film when cell temperature drops below the configured threshold — preventing cold-charge damage in cold-climate installations.
🔌 CAN + UART — Inverter Integration & Display Support
CAN bus enables direct BMS-to-inverter communication. UART connects to LCD displays for local panel monitoring.
