Overvoltage Error during setup

OK. I've perhaps been abit of a tit.

I have purchased a flipsky Mini FSESC4.20. While I was waiting a week for it to arrive I noticed the maximum voltage of this VESC is 60v... so I calculated that at maximum charge I can build a 14s battery which gives 58v.

I received the vesc today and plugged everything together and tried an auto detection or whatever its called... and I get a detection failed error on the screen after 5-10 seconds of nothing happening. So I went online and found that if I type 'fault' in the vesc tool terminal I can get a fault code to show... and its showing "FAULT_CODE_OVER_VOLTAGE". 

Is there any way of getting this to work without having to dissect the neatly wrapped battery... ripping the 14s bms out and forking out on a 13s battery to lower the voltage? 

Now like a dumbass I ignored the quite clearly labelled flipsky mini FSESC4.20 labelling which says "3s - 13s LIPO' as I calculated that a 14s battery will never exceed 60v.

Any thoughts and suggestions? 

You live. You learn. Ooops.

Thanks,

Arran.
