Frequently Asked Questions

Which battery chemistries and cell counts does this BMS support?

It covers 7–16S Li-ion, 8–16S LiFePO4 and 14–16S LTO packs, so the same board family fits lithium-ion, LiFePO4 and LTO battery banks within those ranges.

What current can the JK-PB2A16S-20P handle?

The product page rates it at 200A maximum continuous charge and discharge with up to 400A instantaneous. The family summary also lists a 100A–300A range, so confirm the figure for the model you select.

How many BMS units can be paralleled?

Up to 16 BMS units can be networked and monitored in parallel over RS485, which suits racked or stacked energy storage installations.

Which communication interfaces are available?

CAN plus dual RS485, with OEM/ODM communication protocol configuration available. Bluetooth app and PC commissioning cover monitoring and parameter management.

What is included with the BMS?

The standard package includes the main board, interface board, battery sampling and connection harness, communication cable and accessories, heating and activation accessories according to configuration, and mounting hardware. Cells, enclosure, inverter, power cables and busbars are not included unless quoted.
