I have a 15hp 4stroke Yamaha outboard that I want to charge two deep cycle batteries with. I plan to use the dual batteries hooked up in series to power a 24 volt electric outboard that I will use as my *****ing motor. Do these batteries need to be hooked up in sequence while charging 12volt or can I leave them in parallel while charging? It would be no problem to mount a switch if I need to but thought I would ask

It is ok to charge tho batteris in parrallel, but it can create issues. The most relevent of which is the fact that the batteries will level out to the lowest battery. In other words-- if you have a good battery and one one its way out, the poor battery will draw down the good one until they level out. Not Good. The way to do it is with a switch that separate the two batteries and allow charging of each one individually or both if you so wish. As far as the 24volt *****ing motor is concerned your batteries need to be in series of course. I would use an isolation switch before the plug in for the motor.

Do you see what I was getting at

I have done this before with a *****ing motor sharing a starting battery, you will have to use an isolation switch hook the batts in parallel for the *****er and tap off separate leads for the motor, u will have to charge them one at a time. I would charge number one on the away out and number two on the way back in.
Check ur voltages before u start ur motor, You're gonna have a lot of wires, Eventually I gave my *****er its own deep cell batteries, because the starting batts wud not hold much runtime.
