    electric diving scooter

    I'm way too much of a noob to be developing a whole new thing lol. And all these comments about Lithium and buoyancy, i'm going to use way more packs than the one pack of lead acid which is like 12V10ah or something so the 9 packs of 4s8ah lithium will even the effect out my boys

    Thanks for the reply! What do you mean 5 amps past the max with the controller? Probably because of my original post? It was just a calculation 44Vx35A=1540W. I don't have a controller atm and if i'm going to buy one i'll make sure it's 40A+. Would buying 8ah 4s turnigy packs make up less...

    electric diving scooter

    Thanks for the reply! I don't really plan on using the scooter with diving gear nor do i even have gear. It's just for recreational purposes at a nice beach with clear waters. The only thing i will have on is a boardshort and swimming glasses.

    I know 400A is a ridiculous number. But it's nice to know that i can buy 12 packs of 4s and pick the 20C ones which would easily give me a nice max discharge. I'll only use 50A max so that's great. I'll put up some pictures tomorrow!

    The '400A rating' you said, does that mean i could run 400 Amps through it? I see in the details: max discharge 30C. So that would be 30x12=360A at a max discharge. I didn't even know you could add those things all up, it probably has to do with the fact that the current is being distributed...

    Thanks for the calculation you made there as a noob i had no idea! Again a very helpful reply! So you say it needs 8 times the power, but that can change when i use a more efficient propeller i suppose? Any sites where i can buy light-weight propellers with a similar diameter to the one they...

    electric diving scooter

    Thanks for the reply! So the only thing you changed was the battery, correct? You took it out of the seadoo scooter and replaced it by a 4s lipo pack. How do you know the motor would be capable of putting out 533W in the first place? It probably couldn't hence the reason it all melted down...

    Yeah i'd say you're hijacking the thread. Just make a new thread.

    electric diving scooter

    Thanks! And i am of course aware of the fact that a 200% increase in prop speed does not automatically mean the speed is going to double. That's not what i claimed i don't get where you get that from.

    How are my boys doing? :D I'm looking for a 1.5kW electric motor that can be ran at 44V and 35A. I would like the kv to be around 450. Recommendations of an ESC would be welcome as well. Thanks boys

    electric diving scooter

    I'm building a diving scooter. Motor is going to be aroun 1.5kW, ran at 44V and 35A. So i'm looking for a 12s4p setup which would allow 44v20ah if all packs are 5ah. I am limited in the space i can use so i would like to know which option would take in the least amount of space. I was thinking...

    electric diving scooter

    Yes i am a noob. http://www.hobbyking.com/hobbyking/store/__24567__HobbyKing_30A_Boat_ESC_3A_UBEC.html I'm going for about 1.5kW motor at 44V so 35A, so this ESC should do the trick right? I suspect it's already programmed and ready-to-use? In the description it says: Low Voltage...

    electric diving scooter

    What do you mean? When i look online for electric motors i always see the voltage it should be ran with so i don't want to run any risks and have the motor blow up. Also do i need a new controller? I suppose i can still work with the one they have? I was thinking of buying this type of motor...

    As for battery pack: http://www.hobbyking.com/hobbyking/store/__26789__Turnigy_nano_tech_A_SPEC_5000mah_12S_65_130C_Lipo_Pack_.html This is a 12s 5ah. If i buy 4 and put them in parallel of these that would make 44V and 20ah, correct? Any better suggestions? Maybe buy these...

    electric diving scooter

    I can't find it anywhere but a Bladefish seascooter does 500RPM but it has a larger propeller. I'd say the seadoo would be 1000RPM range I was looking at a motor with 2100kv so maybe that's the issue since it would get up to 100k RPM at 48V. Does somebody know a formula or sth or how much more...

    electric diving scooter

    I'm looking to double performance on a diving scooter. It's a seadoo scooter It's 5kph basic and i want 10kph. The setup on standard is 300W at 12V i believe with a basic propeller. Not looking to change a lot, i don't know what the whole deal is with the ESC and everything and gearboxes etc and...

    electric diving scooter

    Thanks for your response. I had no idea that it would take 16 packs of 6s to get to 88v at 20ah. I'm not going to be able to fit 16 packs of 6s in a DPV in a million years. Good night sweet prince.

    electric diving scooter

    Actually what i was trying to do is get the voltage to 88v from getting the 4 6s packs in series (all packs 5ah so the 24s pack 5ah) and add 20ah to that by putting 4 1s packs (with each 5ah) in parallel. Does that work?
