So you're saying that you used to see higher currents and better acceleration at low speeds? Yes? No?
Bill had some good thoughts. Also, have you checked all the cells under load, to make sure that each one is doing its part? I know nothing about the Kelly controllers except what I read, which is that they're not exactly top shelf products. This may not apply, but I remember the old PMC DCC range of controllers which, if I'm not mistaken, used the E/C junctions of the bipolar power transistors as shunt resistors for the current limit. As the transistors aged, their E/C resistance rose, causing the controller to limit at lower currents (and causing acceleration to weaken). A few owners tried cranking up the limit control in response. Not too surprisingly, they fried the power transistors.
