150‑200A BMS

The 150-200A BMS category houses our most popular and versatile battery management systems. Designed for high-current lithium battery packs, these boards handle demanding loads while maintaining precise cell-level protection and active balancing.

What Is a 150-200A BMS?

A 150-200A Battery Management System is built for large-scale battery applications where continuous current draw reaches 150 to 200 amps. These advanced BMS boards support higher cell counts (up to 24S for 72V-87.6V LiFePO₄ systems) and include active balancing technology that equalizes cell voltages during every charge cycle, maximizing battery capacity and lifespan.

Common Applications

  • Solar Energy Storage Systems: Residential and commercial ESS with 48V-72V battery banks
  • Electric Vehicle Conversions: Car, truck, and bus EV retrofit projects
  • Industrial UPS: Large-scale uninterruptible power supplies for factories and telecom
  • Marine & Off-Grid Power: Electric propulsion and remote area power systems
  • Golf Cart & Utility Vehicle: High-performance electric utility vehicles

Why This Category Is Our Best Seller

The 150-200A range covers the majority of real-world BMS demands. Whether you're building a 16S 51.2V LiFePO₄ battery for home solar storage or a 24S 76.8V pack for an EV conversion, this category has the right board. All models feature active balancing (2A), Bluetooth for real-time cell monitoring, RS485 and CAN communication for inverter integration, and a rugged PCB design built to handle sustained high-current loads without overheating.

Every 150-200A BMS ships with a complete accessory kit: main unit, communication board, communication cables, balance wires, activation switch wire, heating wire, B+ cable, and terminal hardware. Backed by a 3-year manufacturer warranty and worldwide shipping from JKVOLT.
