JBD ESS 16S - 100AMP SMART BMS

A hardware-only Battery Management System (BMS) designed for 16S LiFePO₄ (LFP) battery packs (nominal ~51.2 V), rated for 100 A continuous current.

This board provides essential protection & cell balancing for high-voltage 16-cell battery systems without any smart connectivity or app integration — purely hardware protection logic based on voltages, currents, and temperature.

Key Features

Here are the main functional features of a JBD 16S-100A Hardware BMS:

Current & Voltage Specs

Rated Continuous Current: 100 A discharge

Charge Current Capability: ~60–80 A (varies by exact board & cooling)

Nominal Pack Voltage: ~51.2 V (16 cells × ~3.2 V for LiFePO₄)

Max Charge Voltage: ~57.6 V (16 × ~3.6 V LiFePO₄)

Protection Functions

Over-charge Protection

Prevents individual cells from exceeding safe high voltage.

Over-discharge Protection

Stops discharge before cell voltages fall too low.

Over-current Protection

Cuts off current draw if the pack draws too much.

Short-circuit Protection

Rapidly disconnects if a severe short occurs.
