The Original JK 200A (300A Peak) Universal Smart BMS with 2.0A Active Balancer

The JK 200A (300A) is a high-performance Smart BMS designed for medium-to-large battery packs used in solar storage, electric vehicles, e-bikes, UPS systems, and industrial power solutions. It features 2A high-current active balancing, 200A continuous discharge, built-in heating chip, and integrated Bluetooth, making it one of the most advanced BMS solutions for LiFePO4, Li-ion, and LTO batteries.

This BMS supports 7S to 20S battery configurations and includes CANBUS and RS485 communication for direct connection to solar inverters and advanced monitoring systems.

Features:

• Supported battery types:
  • Lithium Iron Phosphate (LiFePO4/ LFP)
  • Lithium Titanate (LTO)
  • Lithium Ion (Li-ion)
  • Lithium Polymer (LiPO)
• Supported number of cells:
  • LiFePO4: 8S ~ 20S
  • LTO: 14S ~ 20S
    
  • Li-ion/ LiPO: 7S ~ 20S

• Bluetooth Supports: Android and iOS
• Single cell can charge range from 1V ~ 5V. (Configurable depending on cell type LFP/ LTO/ Li-ion/ LiPo etc.)
• This smart BMS works with any number of battery cells from 8S to 20S, supports charge and active balance.
• This BMS provides balancing accuracy ± 5mv.
• Supports Bluetooth, CAN and RS485 protocol to communicate with Solar Inverters for remote monitoring
• Configure the charge/ discharge/ balance voltage and current via Bluetooth.
• Active balancer technology using the non-energy consumption energy transfer technology
• When the voltage difference reach the threshold value (default > 4MV, can be set), it will be automatically start the balancing process
• BMS can support 8 - 20S battery cells and select the cell count automatically. So, a single BMS can suppports wide range of battery packs.
• It has various protection functions: Over-charge, Over-discharge, Coulomb meter, Temperature protection
• Multiple BMS can be balanced in Cascade Mode.
• The charge range of single battery is 1V ~ 5V, and the accuracy is ± 5mv
• Bluetooth communication is standard and supports Android and IOS to
  monitor the battery status in real time
• Configure the charge/discharge/balance paramter by Bluetooth
