Voltage Platform & Load Class — Where This BMS Fits
📊 8S–20S (24V–60V) — Light to Mid-Load Applications
The 8S–20S platform covers the voltage range used by commuter e-bikes and electric scooters (24V–36V), through to light electric vehicles and backup power systems running at 48V–60V. At 100A, this BMS is sized for light-to-mid load applications — commuter and recreational use, small UPS systems, and telecom backup packs where sustained high-current draw is not the primary requirement.
⚡ 0.6A Active Balancing — Energy Transferred, Not Wasted
Passive balancing burns off excess cell energy as heat. The JK-BD6A20S10P actively redistributes charge between cells, keeping your pack balanced and efficient through every cycle — more usable capacity and longer pack life compared to passive alternatives.
💻 Bluetooth + UART — Two Ways to Monitor
Monitor via Bluetooth app on your phone, or connect an optional LCD display via the built-in UART port for a dedicated panel display — no additional adapter required.
