Original Bosch spare parts are the only way to guarantee your safety. The Bosch eBike system components are perfectly adapted to one another and provide maximum efficiency and safety. It might seem simple but there are many safety measures not present in aftermarket batteries so we highly recommend against this. It should also be noted that there are many new regulations coming online requiring UL for batteries and chargers so we recommend checking with those requirements.
