Description
BMS LFP 20S 50A JBD (ZP20S007) (963s)
JBD 20S 50A BMS (ZP20S007) is a reliable battery management system designed for 20-series LiFePO4 battery packs (~64V nominal). It supports 50A continuous charge/discharge current and provides advanced protections such as over-charge, over-discharge, over-current, short circuit, and temperature protection. With passive cell balancing and common-port design, it ensures safe operation and longer battery life for electric vehicles, solar energy storage, and lithium battery systems.
The JBD BMS LFP 20S 50A (ZP20S007) is a high-quality Battery Management System (BMS) designed specifically for 20-series LiFePO4 lithium battery packs. It supports a 50A continuous discharge current, making it suitable for medium-power applications such as electric scooters, energy storage systems, and backup battery packs.
This BMS monitors cell voltage, pack current, and temperature in real time to ensure safe battery operation. It integrates multiple protection mechanisms including over-charge protection, over-discharge protection, over-current protection, short-circuit protection, and thermal protection, which help prevent battery damage and improve system reliability.
The system uses passive cell balancing technology to maintain equal voltage across all cells, improving battery efficiency and extending battery lifespan. The common port design simplifies wiring by using the same port for charging and discharging.
Its compact PCB design with efficient heat dissipation makes it suitable for integration into EV battery packs, solar storage batteries, UPS systems, and DIY lithium battery projects.
