I'm sure you can look around for an application for that motor. If not, it won't be an extreme loss. That voltage cut off and you understanding something is wrong saved all 3 parts of your power system from no longer working and becoming dangerous.

Besides from selecting a motor that has too high of a kv value, you have also selected a battery that does not quite have an adequate discharge rate. Be certain you match the correct battery to your system so that it can supply no more than 80% of it's maximum discharge rating.

It would be worth reading and learning a more effective way to pick a power system.
