I just got my new boat and it came with a one 24 series cranking battery. I have a 36 V trolling motor and bought a 31 platinum series Diehard for the new cranking battery and was thinking of using the 24 series that was the cranking battery and use it for one of the trolling batteries. I have two new Diehard 29 series batteries that I bought today and the 24 series for the trolling motor, is this a problem to mix these two? I also have a three bank charger that will charge the trolling motor batteries. So for the breakdown I replaced the smaller cranking battery that originally came with the boat with the big 31 Series Diehard, then I want to put the 24 cranking series and use it with the the two 29 series deep cycles to run the trolling motor.
