Thats the thing I'm reading all the info and it doesn't really explain the real life implementation of ground. On my electrical panel I have a common negative bar for 12v house battery and all the DC breakers/circuits . On the other side of the panel there is AC panel with separate bus bar for...

Ok it makes sense that they connected at the engine between ac and DC, didn't think about it. So theoretically I can just connect those together to get common ground for both ax and DC. Per electric motor vendor, it is isolated from prop shaft so it's not connected to water so I'm guessing there...

And here why I'm getting confusing answers. Here is the link to west marine and point 4 talking about connecting ac ground to DC negative https://www.westmarine.com/WestAdvisor/Ten-Deadly-Conditions

Hopefully I posted in the right forums, I'm hoping some of the users did the same conversion and had to deal with the same setup and questions like this one. Little background story: converting sailboat from diesel to electric motor. Ended up like everyone else buying 20 cells from Amy, with 16...

Well I'm finally now in the process of swapping my acid house bank 12v to LifePo4 bank I'm building out of 4 EVE 285ah cells. Was going to finish my engine to electric swap first with 48v battery bank before changing the separate house bank but as of last night one of the Walmart "deep cycle"...

Egg, do t have enough to double them. Anybody knows where maybe I can get heavy duty busbars copper tin plated on American side? Dont want to wait again for boat shipment. Or should I just make my own out of copper pipe? Any recommendations on how , what size, for 200a max current on 48v system?

Received these cells and ready to put them together in simple 16s config. I'm starting to doubt the bus bars that Amy sent me. Should I just make copper ones? This is for electric motor that will pull max 200a. What would you recommend as far as bars? Picture below on bars that I received with...

Thank you to everyone posting. Well.. finally pulled the trigger for 20 EVE grade A cells from Alibaba 280ah each. Now waiting game and use that time to remove existing fuel tank and fuel lines. Thank you for suggesting to message Amy, price was way lower in comparison to just ordering it...

This is the breakdown of speed and amps usage for my particular boat. Speed and Power: Speed & Power QuietTorque 10.0 48v air cooled PMAC Motor System Kts Amps Watts (In Quiet Seas) 2.6 10 480 3.3 20...

Can you share a link for those cells? How about BMS?

Yes definitely will use BMS, not sure which one yet. As far as motor is 10kw at 48v so max draw is 200a, that is why I would like to build 300ah bank. Its a 32' freedom sailboat with 10k displacement. I should have enough space on center line where the fuel tank is to do 100ahx3 then in series...

Just joined this forum and see lots of good info and links to battery cells. I just purchased a motor from electric yacht and in a process deciding on battery bank. I don't have 12k laying around for 300ah for battleborn setup so I'm leaning towards building my own 48v battery. I found some...
