The Heart of Your Powerwall: Professional-Grade Inverter Sync and Massive 300A Power Delivery.
JK BMS V19 PB2A16S30P | 300A Continuous Discharge | 2A Active Balance | 8S-16S Li-ion/LiFePO4/LTO Smart BMS
The V19 JK-PB2A16S30P is a high-performance Inverter-Ready Smart BMS designed for 8S to 16S battery banks. Specifically, it is optimized for 48V LiFePO4 systems, delivering a formidable 300A continuous discharge. It features a 2A active balancer that maintains cell health far more effectively than standard passive models. Furthermore, with built-in CAN and RS485 communication, it integrates directly with top-tier inverters like Victron, Growatt, and Pylontech. Consequently, it is the premier choice for high-end residential solar storage.

product description
Professional Solar Integration with the V19 JK-PB2A16S30P The V19 JK-PB2A16S30P is engineered to be more than just a protection board; it is a communication hub for your energy system. While standard BMS units act independently, this Inverter-Edition model “talks” to your solar inverter. This process allows the inverter to adjust charging rates based on the actual health of individual cells. Furthermore, the massive 300A capacity ensures that your home can run heavy appliances like air conditioners and pumps without stress. As a result, you gain a smarter, more efficient, and longer-lasting battery bank.
Why Choose the PB2A16S30P Inverter Edition?
Native Inverter Protocols: This model comes pre-loaded with RS485 and CAN protocols compatible with major inverter brands. This process enables “Closed-Loop” communication. Therefore, your inverter receives precise SOC and cell voltage data directly from the BMS.
Massive 2A Active Balancing: Large 48V banks often suffer from cell drift over time. Unlike passive balancers that only work at the end of a charge, this 2A active system moves energy between cells constantly. Consequently, it keeps your pack perfectly balanced and maximizes usable capacity.
Heavy-Duty 300A Performance: With a 300A continuous rating, this BMS supports loads up to 15,000W. Specifically, it features a robust thermal design with high-quality MOSFETs to handle extreme currents with minimal heat buildup.
Scalable Monitoring: Beyond its wired communication, the BMS includes integrated Bluetooth for the JK App. You can monitor cell voltages, adjust protection limits, and view historical data on your phone. Thus, you have total control over your power system at all times.

Smooth cooperation, seller answers all questions.
Ich habe diese hochbelastbare 300-A-Schutzplatine in meinen 16S-280-Ah-Heimspeicher eingebaut, und die CAN-Bus-Integration in das Victron-System ließ sich in nur zehn Minuten erfolgreich konfigurieren.
Sehr gute Qualität! This PB series board made building my DIY server rack battery so much easier. The form factor fits standard mounting configurations perfectly and having the dry contact relays allows me to automate an external exhaust fan for the battery room. Cell matching is perfect thanks to the 2A active balance. It is definitely worth the premium price if you want a reliable, smart ESS setup.
This protection board is the most expensive model in the PB series. Jikong is quite well-known online, so using their BMS gives me greater peace of mind. It is currently operating normally, and I will reach out via email should I encounter any issues.
We live entirely off-grid, so our batteries are our lifeline. We upgraded to the JK-PB series for the 300A capacity to handle our well pump and workshop tools simultaneously. The unit is rugged, the connections are secure, and the ‘Smart Sleep’ mode has been great for saving energy during low-production winter days.
