The Original JK BMS 150A/ 300A (Max) with 1A Active Balancer Universal and Smart BMS

The Original JK 150A/ 300A Smart BMS is a universal, high-performance battery management system designed for LiFePO4, LTO, Li-ion and LiPo battery packs. It supports 8S to 20S battery configurations with an integrated 1A active balancer, Bluetooth monitoring, multiple protections, and communication protocols such as CAN and RS485. This smart BMS is engineered for high-capacity battery systems used in EVs, solar storage, power backup, e-scooters, energy storage systems, and industrial applications. It automatically identifies battery chemistry, provides real-time monitoring, and ensures long-term battery safety and performance.

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.
