Adaptto do not recommend voltages higher than 22s, just because something does work (24s) does not mean it's a good idea. As well as the fact that you're running very close to the voltage limits, there's not really any advantage in volting up using this controller. Using OVS you're able to put down full power to 50% higher of the standard KV - my Cromotor would max out at 60Km/h on infineon crystalyte controller, on Max-e I have had it up to 90km/h and still pulling using exactly the same battery pack. If you still desire speed more than 50% higher than its winding, you're using the wrong motor in the first place! My cromotor no load with OVS in a 24" wheel is beyond 99km/h on 20s (as high as the display goes). How fast do you really want to go on a bike?
18s-20s I believe is the sweet spot for battery packs intended for use with the Adaptto controllers. There's no real justification for higher than that. It adds complexity (more cells, more cell level monitoring wires), it adds risk that comes from higher voltages and building a 22s pack is a lot more difficult from hobby lipo than simply paralleling off the shelf 4s packs and plugging them straight into the BMS. The old school mentality prevalent on this board (which is absolutely correct in context of older controllers) is to volt up for more power - this just simply isn't required with Adaptto. Just increase current! The disposable nature of the basic trap controllers meant that blowing up some fets wasn't such a big deal, blowing up a max-e is no fun.
