Well for some reason, I thought I read a while ago that the bionx controll used 48v FETs. Not sure why I thought that but thought that is what i read some where and had not had time to double check. But reading around sounds like the newer ones (mine is a can based system that I got in 2011) it should have the 75 v parts. Which got me thinking, I have a second 2590 battery sitting here which would give me another 14-16 volts. Which wold put the max voltage maybe around 60 when fully charged ( my 26v bionx battery measures 28 when charged and the others can gt to around 16). I am sure the voltage when in use drops some so would have a good safety margin. Wondering if that would be to much. I work with fets all the time at work, so i know they can be easily damaged, but also ive swaped plenty of them, assuming when they nuke they dont damage the boards, or take the gate driver chip out should be fixiable.
Anyway thinking about giving it a try, if nothing else to see what another 15v might give for a top speed. Guessing it probably is a moot point as I would suspect the extra voltage would cause my range to drop making even more making running that way impractical. Course also the issue that there would not be enough time to charge 2 2590 batteries during y work day seeing I only have a single battery charger.
