We know the maximum possible speed is that of light in a vacuum. But is there a maximum possible acceleration too?

In general relativity and in quantum mechanics there is no limit to acceleration. But if it turns out that there is a fundamentally shortest length of time, then there would be. In particle physics, decays are usually (if not always) considered to be instantaneous. In any case, if a nucleus emits a beta particle, it ends up going at almost the speed of light, and the decay takes very little time.
