菲律宾采购需求：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 looking to source a battery management system that can handle a current rating of around 20A. It's crucial that the BMS features include built-in overcharge and over-discharge protection, as well as balancing capabilities. These functions are essential to ensure the longevity and safety of the batteries we'll be working with. Additionally, I would appreciate details on the size and weight of the unit, along with information about its efficiency and operating temperature range. It would be great if you could provide any relevant certifications or compliance information, as that can influence my decision-making process. Please send over your pricing and lead times so I can evaluate how this fits into our project timeline.
