• What role does a Battery Management System (BMS) play in maintaining battery health?
  A BMS monitors voltage, current, and temperature to protect against overcharging, deep discharging, and overheating. It balances cell charging and discharging, ensuring optimal performance while extending the overall lifespan of the battery.

Others

• Is it better to have 2 100Ah or 1 200Ah battery?
  The decision between having 2 100Ah batteries or 1 200Ah battery depends on your power requirements and preferences. If you have high power demands or need to run multiple devices simultaneously, opting for two 100Ah batteries can provide more power and flexibility. However, if your power needs are moderate and you prioritize simplicity and space-saving, a single 200Ah battery may be a better choice. Consider your specific needs to determine the most suitable option for you.
• What voltage is a fully charged 12V Li-ion battery?
  A fully charged 12V Li-ion battery, such as a LiFePO4 battery, will typically have a voltage range between 13.3V and 13.4V.
