Apex Vertical V3 Key Specifications

JK V19 200A BMS, Touchscreen and Monitoring

The included JK PB2A16S20P V19 BMS is designed for a 16S LiFePO4 system. It provides 200A current management, 2A active balancing, battery protection and Bluetooth app monitoring. The 4.3-inch touchscreen gives local access to key battery information.

CAN and RS485 are available for communication with compatible inverter systems. Compatibility depends on the exact inverter model, protocol, firmware and BMS settings, so confirm the inverter model before assembly.

Which LiFePO4 Cells Fit the Vertical V3 Enclosure?

The enclosure is intended for 16 matched 3.2V prismatic LiFePO4 cells. Common capacity classes include 280Ah, 302Ah, 304Ah and 314Ah. The completed battery will have a nominal voltage of 51.2V, while its nominal energy depends on the selected cell capacity.

Before ordering, compare the cell width, height, depth, terminal spacing and terminal position with the enclosure and busbar layout. Do not select cells by capacity label alone.

Vertical Enclosure, M8 Terminals and DC Breaker

The Vertical V3 / L3 design keeps the completed battery in an upright enclosure for stationary home energy storage, off-grid and backup-power projects. The confirmed kit uses M8 external power terminals and includes a DC breaker.

With an IP20 rating, the enclosure is intended for indoor installation or a dry, protected equipment area. It is not a weatherproof outdoor cabinet.

Assembly and Safety Requirements

• Use 16 matched LiFePO4 cells from the same model and batch whenever possible.
• Follow the cell manufacturer's terminal torque specification.
• Verify polarity, insulation, busbar placement, BMS wiring and breaker installation before energizing the system.
• Match cable size, system protection and inverter current limits to the completed battery design.
• Assembly and commissioning should be completed or checked by a qualified person familiar with high-current DC battery systems.
