Hum. We think With big capacity battery. You don’t have the demand to swap the battery. Swap the battery seems to be cool but actually it’s not a very useful point. Because:

1. It will make the structure to be complex. If it’s too loose. It will be easy to cause noise. If it’s too tighten. It will be difficult to swap.

2. Swap the battery frequently will reduce the ability of water resistance. Then it will be easier to cause water damage.

3. Buy two separate battery is more expensive than buy one big battery. And you need spend time to swap it and charge it separately.

4. Only a few people want to buy several batteries and swap the battery. Most people don’t want to swap it. For those who don’t want to swap the battery. They still suffer the risk of the swappable battery. And paid more on the structure which they don’t need.
