We have a Mini from ~2019 with the stock 48v/14ah battery. It is my wife's bike, and I'm hoping to bring it up to parity with my Joulvert in regards to it's range. Joulvert made me a 48v/26AH battery, so it goes almost twice the distance.

What are my options for getting something closer to 26ah for the Mini?

Thanks in advance.
