Hi Allan, I'd be curious to know what you see as the advantages of implementing packs assembled from 18650 or 21700 cylindrical cells.? I considered that option myself before ultimately settling on

Larry, since you have been experimenting with Li battery cells, what are your thoughts of using packs of the 18650 cells, as found packaged in some of the EV cars, such as the Tesla? There seems to be

I have been experimenting with battery assembly projects for a couple years. My first opportunity was an electric forklift upgrade from lead acid to lithium iron phosphate ?The project really opened

Graeme,By the way, if you're planning to burn about 1000A for a long time, a Honda 2200 generator would do fine to provide that (it defeats the purpose of the "green" effort, but at least you still

I will send pictures. I found some great plastic heavy duty battery boxes at a marine supply store. Try west marine. Very sturdy boxes designed for batteries. I also found a husky storage box at Home

Larry, Really interesting information. I'm very curious about your sources of materiel (batteries, boxes, BMS, etc) and about your overall design & approach. In particular it's interesting to me that

John Thank you very much for the info. I think that this will work out perfectly. I will get a small generator to extend range for emergencies. [email protected]> wrote:

Graeme, I ran some experiments on a a Catalina 22 with a Torqeedo 4R - which is probably the closest recorded data you may find with that motor... At 4 to 4.5mph, I was burning 800-1000W.? ?At 48V,

Hi I bought a Torqeedo 4.0 with 4 12v 30 amp batteries. The boat is a 23ft Bayfield sailboat weighing 3500 lbs . I am wondering the approx. range I can get at 4 knots. The hull speed is 6 knots. Thank

After I assembled lithium iron phosphate?3.2v 90 ah cells in series and parallel to achieve 4 12v 360 ah cells. I put them in 4 heavy duty plastic boxes. Then installed the bms. Before inserting in

Yes, I mounted a Master Airscrew 15x7 3 bladed pusher propeller.? I think it will need a fairing between the motor and prop to keep undisturbed water on the blades, as well as, a trailing fairing on

Larry, what size and displacement is your vessel? Also, where are you (Keeping temp down in Tampa Bay would be more challenging than Victoria CA) and what are you using for ventilation? I would love

I got my motor and controller from Thunderstruck-ev.com. I just added the batteries and in my case generators for my idea of how I wanted to use the system. They have been extremely helpful along the

Collected some static test data today on a Newport Vessels NV86 - 24 volt, 48 amp rated trolling motor.? I mounted it to a dock and used the stock propeller to document typical current usage

Your “What if”. Is a little smaller then my cabin cruiser style boat. If the hull is Semi-displacement it is technically a Cabin Cruiser, not a Trawler which would be full displacement. Marketing
