南非采购需求：磷酸铁锂电池BMS、BMS管理系统、BMS自动化系统、锂电池BMS、18650电池BMS、主动式电池均衡器

I'm currently working on a project that involves a 300A 48V BMS, and I'm looking to connect multiple battery packs in parallel. To ensure efficient communication between the parallel setups, I need specialized communication boards designed for this purpose. Could you provide me with options or recommendations for parallel communication boards that would be compatible with my system? I'm particularly interested in specifications, pricing, and lead times for these components. Thank you!
