JKBMS JK-B2A24S15P | 150A Smart BMS for Backup Power Supply & Small ESS | 8S-24S LiFePO4 Li-ion | 2A Active Balance

Maximum Balance at 150A — JKBMS JK-B2A24S15P Smart BMS with 2A Active Balancing for 8S–24S

The JK-B2A24S15P brings the 2A active balance platform to the full 8S–24S voltage range (24V–72V) at 150A continuous current — the ideal choice for UPS backup power systems, electric sightseeing vehicles, and electric tricycles that demand both wide voltage coverage and the highest available balance current in its class. When cell consistency matters over the long term, 2A active balancing delivers.

2A Active Balancing — The Highest Balance Current in Its Class

⚡ Why 2A Active Balance Outperforms at 150A

Most 150A BMS boards offer 0.4A–1A of balancing. The JK-B2A24S15P delivers 2A — equalizing cells up to 5x faster than entry-level active balance models. In a 150A pack running daily charge/discharge cycles across the full 8S–24S range, cells are equalized during the cycle, not just at the end of charge. The result: consistently tighter voltage spread, more usable capacity, and dramatically slower capacity fade over the pack’s lifetime.

🛴 Electric Sightseeing Vehicles — Wide Voltage, Full-Day Performance

The 8S–24S range covers 24V to 72V — from small golf carts to larger tourist vehicles. The 2A active balancer ensures cells stay matched even under sustained 150A loads, protecting range consistency and pack longevity across every operating voltage.

🔋 UPS & Backup Power — 24V to 72V

For backup power systems across the full 24V–72V range, 150A capacity with 2A active balancing means your pack delivers full capacity when it matters most — and stays healthy through years of standby cycling. Bluetooth + LCD monitoring gives you instant visibility into pack health.
