I wonder if anybody is aware of the problem that Will Prowse has with
Battleborn batteries.
Here is a link to his latest video responding to Battleborns explanation

It sounds like they really cheaped out on their disconnect. It is not a
proper fuse. No safety agency would accept a fuse built like this.
The type of disconnect they are using is also dangerous if you use their
batteries in series. The first disconnect to open sees the full pack
voltage across its connection. If it's more than about 36v, it can
strike an arc that *will not stop* until a considerable gap is burned.
The proper way to do this is with some kind of current-carrying metal
link that melts when the current is high enough for a long enough period
of time (I^2T exceeds X). Or, there are a variety of circuit breaker
techniques that use something like a bimetal disk that "pops" to the
opposite state to open a contact.
