Overview
The JKBMS JK-BLMK-5A parallel module is designed for use with JIKONG BMS systems (compatible listing reference: JK-B2A8S30P-HC) that have built-in parallel interfaces. This module is used to connect battery packs in parallel via the BMS parallel interface.
Important compatibility note: This product is only for JKBMS with built-in parallel interfaces. If the JKBMS does not have a parallel interface, this device cannot be connected.
Key Features
- Parallel module model: JK-BLMK-5A

Protection & Mode Text Shown (general JKBMS/BMS reference images)
SIX SECURITY PROTECTION
- Over charge Protection: Prevent over-charging Affects battery life
- Short circuit protection: Automatic protection when short circuit protection
- Over discharge protection: Prevent the battery from running out
- over current protection: Prevent the current from exceeding the battery range
- ALL-IN protection: Prevent cable drop or poor contact
- Over temp protection: Prevent the battery from over heating
Smart energy working mode switching
- Storage Mode: “In transportation,storage,offline or wireless transmission off mode, the BMS is in storage mode, which does not consume battery pack current.”
- Normal Working Mode: “When the charger is inserted in the storage mode and off mode, the BMS will immediately return to the normal working mode, and all the protection functions, equalization function and communication functions will return to normal working.”
- Shutdown: “To prevent the BMS from wasting power for a long time and damaging the battery pack, the BMS has an automatic shutdown voltage, and the BMS automatically shuts down when a cell falls below the shutdown voltage.”
- Standby Mode: “When the battery pack is in the static state (no charge and discharge current and no equilibrium current), the BMS will automatically enter the standby state after the set time (1-30 days can be set) is exceeded.”
- Arrow labels shown: Charging activates, Long time unused, Below shutdown voltage
Applications
- Parallel connection of two battery packs using a compatible JKBMS/JIKONG BMS with a built-in parallel interface
