I just joined the forum here. I LOVE this product idea and want one for myself!
I will be meeting with our battery engineer and going over cell options for a 12S system, and if someone can confirm the BEC, ESC, and motors can handle 14S (motors based on manufacture show they are 12S only but I hope I am wrong), if we can do 14S I think that would make for a great solution without the need to change motor KV in my opinion. Maybe the creator of this product has tested 14S already?
14S is a nominal 1300 RPM different, something you would learn and adjust your throttle finger to easily within 1-2 flights. I would be slightly more responsive nothing significant though and in fact, it may feel and be better. It should also lower the AMPS as when volts rise, amps/heat will decrease.
My focus is 100% on my Electric Hydrofoil Surfboard - EFOIL but I want to make a battery and switch solution for this cool OpenPPG product before I buy one for myself later this year. I have dealt with enough Lipo cells that I just simply will not fly with one strapped onto my back that I cannot get off me if flares up.
Has anyone thought of installing thin stainless or aluminum plate behind the battery packs as a firewall of some sort?
So, if I can get detailed stats/specs or the ESC, Motor, and Full throttle AMPS and Average Cruise amps, along with a diagram of how the power switch is wired into one battery pack I will see what our engineers come up with for the battery and high current switch.
What AH size packs are people thinking? 35, 40, 45, 50Ah?
Also, what switches have been used here that have been failing so we can review what does not work as that is half the learning curve, knowing what does not work well.
