A 41v nominal pack voltage denotes your really honing in on the 36v aspect of your motors still I assume to be the same as my footprint being an old etek. Mine actually say 36v on the motors themselves. So I was a little shocked to say the least when I opened them up but apparently they do well way beyond 36v.
Besides I guess a mont709 is the direct replacement more or less so affordable electrical is where it is at. If I'm reading your configuration right you simply flick a switch to go from 48v to 36v which is a very effective controller. Do you have reverse?
Our boats are of a very similar displacement and construction mine being plywood epoxy as well. I estimate that I'm 3500lbs bone dry as in 12 years on the dry.
That is exactly the scenario that is playing out for me as well regarding obtaining and upgrading lithium. It was suggested by the vendor to simply buy a lesser pack and see how the weighting works out with the boat and then if need be double the pack size later on if needed or wanted.
I'm weighing in at around 530lbs for my 400ah 48v pack. Truth be told though with all the other gear I'm probably adding more like 1200lbs on to the final dry weight when it gets picked up in the slings. I'm hoping the travel lift has a guage on it to weigh me.
Are you concerned with the added weight in relation to expected returns or has your experience absolved you of all the range anxiety you may have?
I know roughly that every 1800lbs or so I drop an inch at the waterline.
