Winter-Ready Solar Storage — JKBMS JK-B2A24S20P-HC 200A Smart BMS with Heating, CAN & RS485 for 8S–24S
Solar PV systems and small home ESS installations in cold climates face a challenge that standard BMS boards can't solve: lithium cells lose capacity and risk permanent damage when charged below freezing. The JK-B2A24S20P-HC solves this with integrated heating film control, while adding CAN and RS485 for direct inverter communication — all on top of the 2A active balance platform that keeps your pack healthy for years.
Compatible chemistries: LiFePO4 / Li-ion / LTO

Three Upgrades That Make the HC Version Essential
🔥 Heating Film Control — Charge Safely Below 0°C
When ambient temperature drops below freezing, the BMS automatically activates an external heating film to warm the battery cells before charging begins. This prevents the lithium plating and permanent capacity loss that occurs when cold cells are charged — critical for outdoor ESS cabinets, rooftop solar installations, and any system exposed to winter temperatures.
🔌 CAN + RS485 — Speak Your Inverter's Language
CAN bus enables direct BMS-to-inverter communication for tight integration with hybrid and off-grid solar inverters. RS485 supports SCADA, energy management systems, and remote monitoring platforms. Together they transform this BMS from a protection board into a fully integrated system component.
⚡ 2A Active Balancing — Maximum Pack Longevity
Active balancing transfers energy between cells rather than burning it off as heat. At 2A, equalization happens fast enough to keep cells matched even during rapid solar charge cycles — protecting your investment through thousands of charge/discharge cycles.
