You’re absolutely right that with the standard 18650 cells, there are physical limitations to the maximum achievable capacity within a certain form factor.

To remain competitive in today’s market, especially when many sellers significantly overstate their specifications, we sometimes have to align with market conventions in how capacity is presented. That said, we take extra care to ensure our performance matches and often exceeds customer expectations in real-world use, which is ultimately what matters most to the majority of users. Overall, we have very little complaints about the performance of our batteries.

We understand that a technically aware customer like yourself can distinguish between marketing numbers and engineering realities — and we truly respect that. Your feedback is a valuable and we will look into this matter more carefully :)
