The Mighty Mini pack that I have is made with 30Q cells, 14 series and two in parallel. These are considered 15A capable cells, so the pack would be considered a 30A capable pack since it also has a 30A BMS.
Running this with my BBSHD, I have certainly drawn 30A from it without significant heating.
Running any pack at max current from full charge to dead would not produce the longest pack life. Ebike loads are peaky, and the pack needs to be able to handle that, but we don't generally run max current all the time.
The "range" and "max speed" ratings of an ebike don't occur at the same time, just like the range and top speed of a car don't happen concurrently. Modest speeds increase range significantly.
A folding ebike with a small battery is designed for "the last mile", rather than as a long range vehicle. The goal is to make it small and light but adequate. It can be carried in the trunk, in the RV, or on the bus/train, and then deployed for the last few miles of the trip. It is a brilliant way to augment the transportation system. It can also be more safely stored at the endpoints by taking it inside and keeping it secure rather than trusting locks out in the parking lot.
If considering longer trips with a folding bike such as this, either a second small battery or a second larger battery would be a useful addition to the kit. Then flexibility is increased and the battery complement can be chosen for the day's needs.
