BMS JK PB2A16S-30P

Smart BMS JK-PB2A16S30P: Ultimate Power 300A & Active Balancer 2A (8S-16S)

Looking for the most reliable BMS for a high-performance solar station or industrial UPS? The JK-PB2A16S30P is a professional Power Bank series board designed for extreme loads. With a nominal current of 300A, it can power even the most powerful 8-12 kW inverters without any risk of overheating.

Why is the PB series from Jikong the quality standard?

The PB series is specifically designed for stationary energy storage systems. It features reinforced copper busbars, improved heat dissipation, and intelligent communication ports for integration with modern smart home ecosystems and inverters.

Key advantages of the JK-PB2A16S30P model:

1. Unprecedented current: 300A continuous

Most systems require a safety margin. This board provides:

• 300A continuous discharge current.

• 450A peak load (inrush currents). This is the ideal solution for 48V systems where the load can reach 15 kW.

2. Active balancer 2A — a lifesaver for large capacities

If you use cells with capacities of 280Ah, 304Ah, or 560Ah, conventional passive balancing is useless.

• Active balancing: The board transfers 2 Amps of current between cells, eliminating imbalance in real time.

• Resource preservation: No cell will be overcharged or overdischarged, extending battery life to 10-15 years.

3. Intelligent communication (RS485/CAN/Bluetooth)

The PB2A16S30P series is equipped with a full set of interfaces for professional monitoring:

• Bluetooth: Full control via smartphone (JK BMS app).

• CAN and RS485: Ability to connect to a PC or directly to inverters for data synchronization.

4. Versatile configuration 8S-16S

The board supports assemblies from 8 to 16 cells in series. This makes it ideal for both 24V and 48V systems based on LiFePO4, Li-ion, or LTO.

Technical specifications:

• Nominal discharge current: 300A

• Maximum peak current: 450A

• Active balancing current: 2A

• Assembly range: 8S, 10S, 12S, 13S, 14S, 15S, 16S

• Temperature sensors: 2 external NTC thermistors

• Protection: Full range (voltage, current, temperature, short circuit)

Where is this BMS used?

• Powerful home solar systems: Works with top inverters (Deye, Victron, Solark).

• Industrial UPS systems: Backup power for offices and server rooms.

• Electric vehicles: Powering high-power motors for boats and special equipment.

Package includes: BMS board, balancing wire harness, activation button with LED indicator, temperature sensors.
