You'll notice the BlueTops Scott is using have light-gray cases. The light-gray cases indicate these batteries are designed for both starting and deep-cycle use. If you are using batteries for trolling motors, be sure they are designed for deep-cycle use. The only BlueTops not designed for deep-cycle use are our 34M BlueTops, which are easy to spot, because they have dark-gray cases.
It is also important to make sure any batteries you use in a 24-volt or 36-volt system are identical in age, size and type. Have fun on the water this year and be sure to catch some big ones for us!
