What breaker size do i need to protect 200ah battery

To determine the correct breaker size for a 200Ah battery, we need to consider a few factors:

  1. The battery's voltage: Is it 12V, 24V, or 48V?
  2. The maximum current draw: This depends on the type of load you're connecting to the battery, such as a motor, lights, or a DC-DC converter.
  3. The recommended discharge rate: This is usually specified by the battery manufacturer and is typically expressed as a percentage of the battery's capacity (e.g., 10C, 20C, etc.).

Here's a general guideline to follow:

However, it's always best to consult the battery manufacturer's specifications and recommendations for the recommended discharge rate and breaker size.

Additionally, you should also consider the following:

Remember, it's always better to err on the side of caution and oversize the breaker slightly to ensure safe and reliable operation.
