JK‑B124S15P Smart BMS for 8–24S Li‑Ion/LiFePO4 (25–100 V, 150 A, 1 A Active Balancing)
Reliable BMS module JK‑B124S15P with 1 A active balancing supporting 8 to 24 series cells. Provides protection against overcharge, overdischarge, overcurrent, short circuit and overtemperature. Features Bluetooth and RS485 connectivity, ideal for basic DIY systems.

The JK‑B124S15P is a smart BMS designed for Li‑Ion and LiFePO4 battery packs with 8 to 24 cells in series (25 to 100 V). It delivers a continuous current of 150 A, peak current up to 300 A, and offers 1 A active balancing to extend cell lifespan. This module protects against overcharge, under‑voltage, over‑current, short circuits, and high temperature. Bluetooth and RS485 interfaces allow real‑time monitoring of voltages, currents, temperatures, and individual cell status. Standby current is very low (~6–10 mA). Encased in a durable aluminum housing, it operates reliably within a wide temperature range of −20 °C to +70 °C. With dimensions 162×102×20 mm and weight ~210 g, this BMS is ideal for solar storage systems, battery enclosures, electric vehicles, and industrial applications.
