Looking for a 60V controller

Post by Pegazus » Dec 04 2019 2:16am

Hi,

I already have a 48V 1kw Kunteng controller.

I'd like to upgrade my 13s battery to a 14s battery. The voltage will go up to 58.8V at full charge and I'm not sure that my controller will handle it, can you confirme that ?

On the other hand, I'm looking for a 60V controller compatible with Eggrider V2, I'd be very interested if you had any reference or model in mind for such controller.

Thanks for your enlightened opinion :)

You should go up to 72+, less stress on the components, or why not 90V? so you have room for expansion

My 1000w KT is labeled 36/48v. I've only run it at 52v.

You should be good to go:

63V is a common rating for the capacitors used in controllers. Generally you find passive components in the E-series of numbers, 10, 22, 47, 63, etc.

If it's a "48V" controller it's likely also using IRFB3077 or similar FETs which are rated for 75V maximum.

Open it up a have look see. Does it have 63v or 75 v Caps or ? If 63v it should work. Just like a motor or battery you can melt down long hiills ect.

Hi Pegazus
dont know if it helps, but there is a realy nice guy Paul from "revelpropulsion" who has an eggrider compatible to an ASI BAC 500.
Im not an expert, but if it works with an BAC 800 you would be fine. Maybe you can ask.
Please let us know...
With kind regard from germany

Get a controller rated at higher voltage than what you will regularly use

you will have more margin against failure.

Pushing up against component limits will reduce reliability and lifespan.

Yeah, could shorten life to five years or so. Seriously, open er up, and see if you see 63v on the little cans inside. If you do, its fine to run it on 14s.

I have one controller like that, a 36v 48v, that I still run today. Got it in 2010, and ran it on 14s the entire time. That one is a bit exceptional, other very good controllers I had lasted at least 6 years.

Think about it a bit,,, you will have 58v in that battery for what, a block or two? Then it will drop to 56 or so, and run there for miles. So that's 7v under the 63v limit on the caps.

Thanks for your support !

Will check the cap value and all other references.
