ESC alternative


#62

Hello,

My setup is 12s 100A, I already have an appropriate motor. I am planning to buy this esc. I also plan to fabricate custom cooling for this one so cooling wont be much issue ( I hope). Does anyone have experience with this esc? Would this be an overkill (400A) or is it best to be on the safe side. Any opinions and suggestions are greatly appreciated. Thanks in advance.

ahh. thats the one i bought, aquastar esc 240a, still haven’t ran it yet, had to pause things for winter, (work commitments) i might take off the shrink wrap take a look at possible extra cooling ideas,keep me posted,… any ideas on a amp meter, looked at a few, would be nice to get a live display in real time,

You are going to want WATERCOOLED that will overheat and shut down on you likely ihsan

If you just want a display connected to your battery box, i recommed the “TF02”(search for Tf02 battery gauge), i think i use the 50V 50A type, it can also measure up to 100A with the delivered shunt. It can be used as a gauge, counting up and down the used Ah. The shunt is calibrated well and i used it right out of the box.
It holds the last measured capacity even when switched off completely.
I glued the screen into the top of my battery box:


Do not use the TF01N, it is too small to read it and the buttons for programming are on the front side where you cannot reach them while it is mounted.

To avoid the shunt, you can look into an hall sensor version… I bought one, 100V 100A (better stay close to max value for avvuracy) works just fine. Or, the wattmeter by Hobbyking… That’s cool to… China-shunt, if you read well, are rated 200 but continuous 60A, so…

Its the best i found for money so far. No networking.
72A max. you can easily attach cooling. I use forced air so far.
Isabellenhütte has some very good products.
If you have good personal experience with a product, please post it.

hi,* thanks, i took a look at the tf02, im thinking maybe to go with the 350A model just for safety, but id say the shunt is a good bit larger, it looks perfect, the guys over in esk8 seem to be using them, heres the link, http://www.electric-skateboard.builders/t/installed-and-tested-a-coulometer-fuel-gauge/1753/4
