When selecting a battery for an e-assist system on a recumbent bicycle, what are the implications of choosing a battery with a higher voltage rating versus a higher amp-hour rating, and how do these two factors interact with the overall power output and efficiency of the system?
In particular, how does the relationship between voltage and current affect the performance of the motor, and are there any potential drawbacks to using a higher voltage battery, such as increased heat generation or reduced lifespan?
Additionally, how do the characteristics of the battery management system and the motor controller influence the optimal balance between voltage and current, and are there any industry standards or guidelines that can help inform this decision?
Furthermore, what are the trade-offs between using a higher voltage battery with a lower amp-hour rating versus a lower voltage battery with a higher amp-hour rating, and how do these choices impact the overall range and performance of the e-assist system?
Are there any specific scenarios or applications where one approach is clearly preferable to the other, or are there cases where a combination of both higher voltage and higher amp-hour ratings is necessary to achieve optimal performance?
How do the answers to these questions change when considering the specific requirements of a long-distance touring setup, such as those used with bob trailers, where the added weight and aerodynamic drag may impact the performance of the e-assist system?
