How confident are you in your diagnostic skills? ie → What makes you think this is a controller issue? > same stuttering problems called out in this thread Ah- You are referring to a thread that originated back in Jun 2019 ??? > [@2002 Loss of Power after Lithium Conversion](https://community.electricforum.com/t/2002-loss-of-power-after-lithium-conversion/16328): > > Seeing a strange loss of power at intermediate speeds, almost as if a gas motor was missfiring. Ramps up to speed very fast, at about 20mph or so, if I take my foot off to coast then put it back down to regain speed it starts sputtering. It will catch up but, it sputters all the way. Lithium cells settle to 92.8v Programmed T2 (Controlled Acceleration is now set to 16) Blue Motor [gem2] [gem3] What have you tried on your car? How much of that thread does your story actually parallel? Was this car working well before the upgrade? What lithium did you install? What motor is in this car? When was the last time this motor was serviced? Have you ruled out the other possibilities called out in that topic? Did you rule out too high of voltage? It seems the T2’s have a 50/50 chance of working well above 90v. For whatever reason some just don’t like going up that high and produce unpredictable and confusing results. Chasing gremlins is enough to drive some people cray-cray. Some even decide to let out the glorious smoke much to the delight of JarJarJava here. What part of the country would you be located? --- _[View the full topic](https://community.electricforum.com/t/re-2002-loss-of-power-after-lithium-conversion/26699)._
