Trolling battery?

[brettw]

Just go to Sam's and get two Duracell group 31 deep cycles...and wire in paralell lfor 12 volts... connect to a on board charger that has 15 amps per bank and connect a bank to each battery. You will be able to pull cranks at 1.8 mph all day and they will recharge over night. Then if you decide to get a 24 volt trolling motor later on with more thrust you will already have the batterys for it and you can rewire then in series. Those batterys are 90 bucks ea. at Sam's Club.

I’m sure that would be fine but altering my carefully crafted plan is unlikely

This thread got me thinking a little (trouble, I know).

I have a MK C2 30lb TM on the transom that I use for trolling.

To my knowledge, this just has a variable resistor for speed regulation, which wastes a lot of current at lower settings.

The Maximizer units are drying up and are quite expensive. There are some DIY PWM controllers, but I don't have the resources to build them.

I figure that surely the Chinese are making a simple 12v DC PWM controller, and sure enough, I found a 40a unit on Ebay for 10 bucks and bought one.

I just wish that I had a DC clamp meter to see how much of a difference it makes. I will post a thread once I try it out.
