Today, we’re building a powerful, real-time State of Charge (SOC) monitor for your batteries. Whether you're using LiFePO4, Lead Acid, AGM, or Gel battery chemistries, this setup will give you accurate insights into your battery’s charge level in real-time. But that’s not all — this monitor also includes safety features like current and temperature monitoring, with alerts to notify you of any potential issues. From preventing overheating to catching excessive current draw before it causes damage, this system will help you keep your battery safe and running efficiently. Plus, with the ability to remotely monitor your battery's status, you can easily check your SOC from ashore or at home, ensuring you're always in control of your battery’s performance.
