BMS module JK Smart Li-Ion-LiFePO4 7S-20S 150A BAL 1A RS485 HEAT Programmable with Bluetooth and app support

BMS module to protec against short-circuit, overcharge, over-discharge, with the function of equalizing the voltage of individual cells.

HEAT version with heating control using a heating mat.

Important!: The mat isn’t a part of the set. The BMS allows you to control the heating of the pack until it reaches the positive temperature necessary to turn on the charging

The BMS output can control the mat directly (max. current 3A) or with a relay at higher currents.

The JK BMS is a fully configurable device. This means it can be used with Li-Ion, LiFePO4, and LTO cell packs. It is designed to work with varying numbers of cells (within the range specified for the particular BMS model).

BMS JK have a built-in high-current active balancer and a Bluetooth module for communication with a mobile app (Android, iOS).

To function correctly, the device must be configured via the mobile app. At a minimum, the number of cells and the battery type must be specified.

JK BMS units cannot be used immediately upon delivery without first configuring the parameters in the app to match the specific cell type. Therefore, installation requires appropriate knowledge and skills. Download: Detailed user and configuration manual.

We offer an optional, paid service to configure the BMS according to the specific pack parameters provided by the customer. If you choose this option, please include the number of cells, battery type, and capacity in the order notes.

• Common charge/discharge port – eliminates the need for a separate charging cable.
• Power switch for manual pack activation/deactivation and BMS wake-up upon initial startup.
• Supports charging at the same current rate as discharging.
• High-current active balancer (0.4–2.0A, depending on the model) ensures rapid cell balancing, even in high-capacity battery packs.
• Generates less heat under load compared to competing systems.
• Compatible with a mini LCD monitor displaying basic battery parameters, a large 4.3″ LCD screen with three display modes, and a 3.2″ LCD indicator.
• Intuitive app for monitoring and configuring BMS settings.

It comes complete with a cable for connecting individual cells and a switch. The BT module is built into the device.

JK BMS units allow charging at the same current rate as discharging. This enables the parallel connection of batteries equipped with them without the need for parallel modules, requiring only an overcurrent fuse for protection.

An app must be downloaded to program and monitor parameters.
