Title: Using a capacitor to limit current from LIPO batt
Post by: alfio on March 12, 2009, 06:19:00 PM

Hi ALL
I purchase the lipo batt 10ah 36v from Golden and I´m sad whith the cutoff imposed by the BMS when the current goes to 30 A (in brisk acellerations or hills). This force me to stop, turnoff the key, turn on again and restart the ride. My motor is 750W36V
You think that a capacitor solves it?? How it works? How to do it?
Thank you

Thank´s for response
I´m worried about weight
What size and chemistry you think?

I think you're missing something important here.

750W / 36V = 20A

If you're running 30A, you're pulling more than
1000 Watts in your 750W motor.

That means you're overheating the motor, and
that's probably not a good thing.

You probably want to think about the 1000W motor
if you're planning on regularly pulling 30A.

Thanks for response

After a couple weeks I´m learning to avoid the cutoffs.
I intend to put another pack (booster pack).
If I use a diode to separate the packs may I use a 36V,  2000maH NimH (30 AA)???
