So I have an Ultrex - 36 V system. I've had the boat for a year now with no issues. Recently I noticed my trolling motor doesn't have the power it use to have. Right from the get go. All three batteries are reading a full charge. I'm getting a full reading on the circuit from all 3 batteries but it's acting like when in the past I've had one bad battery in the group and it's only running on 24 V.
Any ideas? Is there a way for me to see how much power is running into the Ultrex itself. I've checked at batteries and the plug and it's getting the 36 V so it says.
100% it's not the same it was. I know it's not running right. Just looking for some ideas.
