JK PBD6A16S20P 8S-16S 200A BMS|Wistek

Just arrived: the JK PBD6A16S20P BMS. It features 0.6A active balancing current, 200A continuous charge/discharge current, and wireless monitoring via a Bluetooth app—making it perfect for DIY energy storage batteries.

Compatible Battery Chemistry

• LiFePO4 (Lithium Iron Phosphate): Fully optimized for 3.2V cells.

• Li-ion / NMC (Ternary Lithium): Supports 3.6V / 3.7V chemistry.

• LTO (Lithium Titanate Oxide): Supports 2.3V / 2.4V chemistry.

Supported Cell Series (S-Count)

• LiFePO4 (LFP): 8S to 16S (24V - 48V Nominal Packs)

• Li-ion (NMC): 7S to 16S

• LTO: 14S to 16S

Key BMS Features & Highlights

• Active Energy Transfer Balancing: Delivers up to 0.6A continuous active balance current via energy-transfer technology, transferring power from higher-voltage cells to lower-voltage cells to ensure cell consistency and extend battery life.

• High-Current Continuous Output: Supports up to 200A (JK-PBD6A16S-20P) or 150A (JK-PBD6A16S-15P) continuous charge and discharge current, with multi-stage overcurrent protection.

• Integrated Smart Heating & Current Limiting:

  • Built-in Heating Control (10A max): Ideal for low-temperature environments to ensure low-temp charging safety.

  • Parallel Current Limiting (~10A): Safely limits inrush currents during battery pack paralleling.

• Comprehensive Multi-Port Communications:

  • CAN Bus & RS485-1: Pre-loaded with protocols compatible with major solar inverters.

  • Dual RS485-2 Ports: Enables multi-pack parallel connection (up to 32 packs) and PC software monitoring.

• Smart App & Wireless Connectivity: Built-in Bluetooth with iOS / Android app support for real-time monitoring, parameter tuning, and status switching.

• Hardware & Pre-charge Protection: Integrated pre-charge circuit (3s default) to handle capacitive inverter loads and dual programmable dry contacts for external alarms/fans.
