60v batt, 50a ykk controller and 72v 3200w motor

[cedierick7]

Hi! I have an ebike (Fiido)

60v battery 17.5ah, 50a ykk controller and 72v 3200w motor (not open voltage)

Is this safe to use? I won't have any problems with it? I'm anxious because I might damage the battery.

And other recommendations?

Thank you so much!

If it's brand new and came from the manufacturer in that configuration, and is built and setup correctly, it's probably safe to use.

If it's something you built yourself, or bought used, we can't know if it's safe or not, based on the information provided so far. We would need complete details on the original bike itself including it's history and maintenance, and then the same on all the parts that are non-original (whatever you've changed, or whatever the previous owner changed).


We might be able to make guesses with less info, but will still need more than you've provided so far. So as much complete detail as you can give.

A cursory search for the bike name turns up 16 inch wheel super cheap Walmart junk e-bikes. Looking at the pictures, I don’t know where you’d even carry a 72V battery that could sustain 50A.

If your battery and motor can really lay down 3kW or more, you’re talking about putting four horsepower into a kid’s toy. Of course it’s not safe. You know that.
