FAQ

What causes the discrepancy between displayed and actual SOC?

The Seplos BMS V3 may stop measuring capacity accurately, leading to inaccurate SOC calculations.

How can overcharging be prevented in the BMS?

There is no way to program float voltage in the BMS, so the only option is to terminate charging to prevent overcharging.

Why does the default charging termination set at 94% pose a challenge?

The default setting may lead to incomplete charging cycles, affecting battery performance.

What impact does the Seplos BMS V3 have on battery charging cycles?

The BMS does not reset to 100% in production environments, causing batteries to stay at high voltage levels unnecessarily.

How does the Seplos BMS V3 affect battery pack performance?

The BMS may display inaccurate SOC levels, leading to confusion and potential performance issues.

Is the Seplos BMS V3 suitable for accurate SOC calculations?

The BMS may have limitations in accurately measuring capacity and SOC, impacting overall battery performance.

Can the Seplos BMS V3 be adjusted for different charging thresholds?

The BMS may not allow for customization of charging termination levels, potentially affecting battery charging cycles.

How does the Seplos BMS V3 impact solar system performance?

The BMS may not accurately track consumption and generation levels, affecting overall system efficiency.

What are the key differences between the GoPro Hero 8 and GoPro Hero 12 cameras?

The cameras differ in design, functionality, and image quality, catering to different user preferences.

How does the Seplos BMS V3 affect standby consumption?

Standby consumption levels remain consistent before and after switching to the BMS, indicating minimal impact on overall energy usage.
