System-Integrated Battery Management — JKBMS JK-B2A8S30P-HC 300A Smart BMS for 3S–8S

The JK-B2A8S30P-HC adds Heating film control, CAN bus, and UART to the 300A / 2A active balance platform — enabling direct inverter integration and small home ESS support. When your battery needs to communicate with an inverter or energy management system, this is the version that makes it possible.

Compatible chemistries: LiFePO4 / Li-ion / LTO

What the HC Version Adds

🔌 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 (HCRPB).

🔥 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 to LiFePO4 cells in cold-climate installations.

📦 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?

  • 🏠 Small home ESS (inverter-integrated)
  • 🔋 Heavy-duty backup power systems with CAN inverter communication
  • 🛥 RV & marine with high-current inverter integration
  • 🔦 Large off-grid power systems requiring BMS-inverter communication
