We are starting back up for this years upcoming robotics season. The last time we competed was at worlds back in the last part of April. Since then, our batteries have sat unplugged in our basement. Now, when we go to use them, they only last for 2 minutes at best. We have reset them, done all updates, let them fully charge/de-charge, etc. and nothing seems to help. Before we reach out to VEX customer service, I just wanted to touch base here on the forum. Any help would be appreciated.
We have about 8 batteries total that all have this same issue.
