I'm still wrangling with the seller. Just yesterday they told me they are the factory store for these chargers. They have been steadfast that they can't be adjusted and yet it is a fact that the output voltage is set according to what the buyer specifies (plus what they decide you need). AKA...obviously settable! I sent them that picture of the PIC controller. They know that I know that the charger can be changed. I have purchased a PICKit3 PIC programmer and they know this too. I have demanded 2 things from them. The first is the uncompiled code they put in the micro controller. The second is fixed compiled firmware set to 82v.If you can't find a spot to fit it on your bike and you can figure out how to adjust the voltage I may buy it from you for another project I have.
