yeah, forgetting to charge it once. The there is no unbalanced load on the batteries because the only draw is from the battery the motor is hooked up to. Once the motor starts it begins putting the power back to the battery.
You'll have to prove to me how it's detrimental other than just saying it's not. I won't go into the physics of batteries here, but a quick Google search will show you that it is not recommended. http://www.allaboutcircuits.com/vol_1/chpt_11/5.htmlAny time you remove energy from a battery or even recharge a battery the physical properties of said battery are altered slightly, changing the AH rating and max voltage of the battery.

I used to keep and extra battery with just my motor attached. No need to charge it and the accessories worked off another battery. One thing I found out was that my Tach quit working. I found that you need to connect the acc. batteries neg - post to the cranking battery neg - post. That solved the Tach problem. If I ever ran down the acc battery it only took 1 cable to jump over to the cranking for some more power.

Has anyone wired their starting cables for the big motor off the last battery in line of the 36 volt trolling motor batteries.
I have had to jump start the big motor before by moving the starting cables over to the last battery in line for the trolling motor batteries. (the battery where the main trolling motor wiring goes up front to the trolling motor) By putting the positive cable on the + and the negative on the - you still are only getting power from that one 12 volt battery.
I've had it configured this way for over a month and through several tournaments. I use the starting battery to run electronics and livewell pumps only.
Has anyone else set-up their batteries this way? I haven't run out of trolling motor battery power yet with it wired this way.
A better solution would be to get a 36 to 12v down converter and run your electronics off of it. Leave the starting battery for starting the motor. I recently did this on mine, I have a 24v TM so I used a 24v to 12v converter. Since the 12v side of the converter is regulated and filtered the power going to the electronics if very clean. The load on the TM batteries is minimal since the load is spread over both of them.
