This morning I headed out fishing and everything was fine, after a while my battery seemed to be drained but felt awfully quick for it to drain that quick. I took it in and charged it. Battery gauge said 100 so I went back out. As soon as I put my trolling motor in for 5 seconds it was back to 0. Went home put a new battery in and was fully charged went out and once again after using it for 5 seconds it was shot. Not sure what the problem is but battery 2 always seems to be 100 charged but the other battery seems to always get shot no matter even if you have a new battery in. Any ideas?

Sounds like there's a short somewhere in the system.
