Hello, I am collecting info and stuff to start on an E-Boat proyect, she is a 7mtrs boat with a 1.5ton displacement. My plan is to get the following performance:
Max speed: 5 to 6 knots
Range at optimal speed: 10 to 12 miles
To get that I plan to use a 10Kw/h 48V battery pack, motor will be an small 8Kw AC motor with a curtis controler.
I have two option on batteries, either going to a EpZS (traction) battery bank with 24 2V cells, or going to 4 big AGM 270Ah battery set. Either case the weigth is around 300Kg.
What is the preferred tecnology AGM or Traction battery?
In case of AGM I have seen that many people use BMS to get an equal charge when using several AGM's in series. Does 4 batteries in series still need BMS under your experience?
In forklift application with big 2V cells I have never seen a BMS, just raw charger voltage applied to the pack, why do you think they don't use BMS?
Thanks for your help.
