Description
The JBD BMS LFP 20S 100A (Model ZP20S006 – b4a7) is a high-current Battery Management System (BMS) built for 20-cell LiFePO₄ (LFP) battery packs with a nominal voltage of 64 V (3.2 V × 20). With a continuous discharge current rating of 100 A, this model delivers reliable power for demanding energy applications while ensuring complete protection and efficient cell management.
It features advanced protection circuits against over-charge, over-discharge, over-current, short-circuit, and temperature faults, providing maximum safety for your battery system. The integrated passive cell-balancing system maintains voltage consistency across all 20 cells, improving overall battery performance and cycle life.
The ZP20S006 design includes a common-port configuration for simplified wiring (shared charge/discharge terminals) and uses premium MOSFET components for high efficiency and low heat generation.
