Hello, I hope I'm posting this in the right forum. I recently bought a used Armada Preditor 72v ebike. The battery pack that came with it is a 72v 32ah SLA battery, and it is either at the end of its life cycle or was not taken care of, because it dies within 30 mins of driving it. I'm in the process of purchasing a new 72v 40ah lifepo4 battery pack. It costs alot of money so I wanted to double check a few things. The controller is rated at 40A with a peak of 80A. My question is regarding the amp hours between the battery and controller...Should the battery match what my controller is rated for. Or should it be higher than the controller. I will post a link to my bikes specs. As well as the battery im purchasing. And I really don't know alot so im just learning as I go so I appreciate everyone's help.
