Hacking a Plus controller
-
A promising start to make a Plus controller run on a 15s battery and no bms. I consulted with Lia and figured out theoretically how to trick the Plus controller run on a Xr/Pint battery with no FM bms. The hack is working on the bench with no error codes, I have to do some tweaking as the app shows a lower battery voltage than actual. If this works, I may try 16s and have a Plus controller run on 15s-16s and no Fm bms, just a generic charge only cheap bms. The app shows a Plus hardware 3206 but with a Xr Gemini 4134 that I flashed in for fun.

@lemur Congrats on getting that working ^-^

Get a feeling modding Plus controllers might become more popular than 4209 XR controllers if this gains speed. Shame the fets only go to 75v else you could possibly go for 18s and have some headroom without U3 and the filter caps going pop D:

@lia I just changed out the two large caps that were rated for 63 v for 80v ones
