Hey folks, thanks ahead of time for any advice, it's very much appreciated!
I'm looking to build a serial battery pack out of LiPo RC batteries. There are a lot on hobbyking to choose from, but I don't know exactly which to choose. I am thinking I should use LiPO because this will be used in a canoe and my understanding is these, should something bad occur, will ultimately be safer in the environment. Powered by a 12v Minn Kota trolling motor (Endura C2 30 12v). Eventually I will get 2 of these motors and have them operate together by remote; but one thing at a time as Id have to learn how to set up a controller, etc. So, battery first and that will probably be fine for season 1! Then later 2 motors for security, etc.
Im disabled and can't paddle well (I can operate like a normal healthy person if needed in case of emergency but muscle exertion causes damage so I have to have next to no muscle activity wherever possible), and with 2 kids in the canoe, I want to be sure I have plenty of battery power - but I also need to be able to carry the battery (plus motor and gear) from the house down to the water, and even if I wheel it down I have to lift it into the canoe, and the exertion here concerns me. This is why I am trying to find a solution around the traditional marine batteries which are too heavy for me. Even 2 batteries that can be swapped would work.
For instance, this battery at 185grams would give me roughly 2.5 batteries per pound (http://hobbyking.com/hobbyking/store...Lipo_Pack.html
), so assuming 2 batteries per pound, 40 of them would weight 20 lbs plus whatever watertight container I make, so 25lbs for 88000 mAh. This is just based on the upper weight I need the battery to be.
I dont know how to convert mAh to show how long this will last against the draw of the motor. Not likely to be use much as we just like to explore along the rivers, but would be nice to know.
Can anyone point me in the right direction and explain how much battery I need, or point me to a place where I can learn how to stripe them? Im assuming to just get some decent wire and solder the lines from the batteries together into a line, unless there is a more efficient safer way that treats the batteries better.
Anyways, this is not my area of expertise but Im certainly willing to learn. I REALLY want to be able to get my children outside in a way that I can physically manage, as this is not their fault, so we can learn and have fun outside together and do a few of the things that would be fun, like fishing or exploring eddys and inlets. So if you could explain what to do here I'd be very grateful indeed. Thank you much!
