For applications such as optimised charging, repurposing triaging and cell insurance calculations, it is important that a model of battery life trajectory can forecast not only the immediate next cycle discharge capacity, but also capacity several cycles into the future. With this in mind, we next investigate how the predictive accuracy of the model changes as we push the model to predict capacity further into the future. In each case, the input comprises the concatenation of the state representation at the start of the nth cycle, s n , with the 'action' vector a n...n+j comprising all charging and discharging currents that will be applied between cycle n and cycle n + j. next protocols that will be applied to the cell, the discharge capacity is predicted with a test error of less than 10% up to 32 cycles in advance.
