Select a JK-B1A model by pack requirements
Use the product specifications rather than the series name alone. Cell count, current rating, balancing, and interface support can vary by model.
Match the battery configuration
Select a model whose supported string range includes the planned LiFePO4 or lithium battery pack.
Check continuous discharge
Choose a current rating that fits the normal load, expected peaks, cooling conditions, and protection design.
Confirm the required interface
Check Bluetooth, display, UART, CAN, or RS485 availability on the individual product page.
