[QUOTE="kofkorn, post: 308349, member: 7076"] Logic here is sound, but the practice is a little more complicated. 1st off, a voltage regulator to handle the power needed by a trolling motor would be very large and need to dissipate a huge amount of heat. On top of that, the cost would be pretty high. See this: [url]https://www.current-logic.com/shop/index.php?main_page=product_info&cPath=5&products_id=32[/url] 2nd, while it may make your motor run more consistently, you would actually get less use out of the batteries than if you had just wired them in parallel (Assuming 2-12v's) due to the 80-85% conversion factor. About 15-20% of your power would be lost to heat. 3rd, when you do this, you would have to keep a very close eye on your battery level, even to the point of having a logically controlled voltage cut-off. If not, you could easily run your batteries down to 30% and quickly kill the batteries without knowing it. You'd be better off getting two good gel batteries, and a good trolling motor with a PWM control or Maximizer. This way you'll be using the batteries the most efficient way possible. Or you could put it together for the giggles. Your choice :) [/QUOTE]
