Start reading and find out why everyone is not using them
neptronix said:What if you decide to use it on a different motor? or change the LVC? or that the 3 speed switch is set incorrectly? do you buy another?
The construction looks awfully poor. If that is a problem, we will find out in time.
If you are particular about having a system that runs perfectly, and want to tune your controller until it does, non-programmability is going to be a problem.
I for one, would be willing to look past the construction issues if these were programmable, being that they are at such a low cost.
That sounds really good. I just looked at the link but could not find the following supports: sensor and sensorless, 100V. Where do you find that info?ian.mich said:http://www.aliexpress.com/fm-store/313864/210769756-492963725/2012-Sales-Promotion-High-quality-48V-1000W-45Amax-BLDC-motor-speed-controller-15FET-4410-s-EV.html
Why aren't people emptying Greentime's inventory, they offer completely custom controllers at any voltage or current, choice of 4410s, 4110s, 4115s, regen, EABS, cruise, and best of all: sensor and sensorless support. They do all this for rock bottom prices. Why aren't these on every ebike? This "48V 1000W" controller does 100V 45A, and all the features I outlined for $45 with shipping. The crystalyte controllers that cost an arm and a leg don't have the same features as this.

DAND214 said:Price for the controller is fair but the shipping is insane.
No break on quanity controllers as the shipping is the same for each item. It's not the cost of the controller they are making money on it's the shipping!
Buy one and shipping is $30 buy 10 and it's $300.00 I never buy 1 from China as you never know if the first one is any good so always order extra. Not here shipping breaks don't apply. $43.00 buy 1 or 10.
Yeah the price is fair but the wait is too long if you need another.
No Thanks.

XLR8 said:Has anyone enabled regen or EABS on one of Leo's controllers? I have the cruise and 3 speed features working but I haven't had any luck with EABS. These controllers are good value for money. I purchased a 60 volt 1500 watt controller for $42 delivered to the door, Australia. The motor runs just noticeably warm and the controller has no obvious heating at all on a normal ride around the streets with small hills.
How long did it take to arrive?ian.mich said:but they are real. i have next to me a 100v 45a controller that has regen, cruise, EABS, sensor and sensorless, and an X8M06 microprocessor. $43US including shipping (got it during a sale a few weeks ago)

I'm after a 48v controller, and what are the benefits of these 4110 FETs in a 48v setup?
Thanks
ian.mich said:not sure, probably around 3 weeks, they're 4410 not 4110. 4110 are the mexican fets that everyones is looking for and they will use them for these controllers if you ask, but they use 4410 from stock and it's all you really need for almost any ebike (4410 are the chinese ripoff of the 4110). unless you are doing some serious biking (crystalyte 5400 series or hubzilla) you don't need 4110s, 4410s take 100v and with 15 of them 45A is nothing. I highly recomend contact leo on skype (leo840522) and not through aliexpress. he can set you up with a custom controller with any LVC and ask for all the features customized to your specs

The IRFB4410 is a different FET from the IRFB4110 and is not "a chinese ripoff of the 4110". Both are IR parts (see : http://www.irf.com/product-info/datasheets/data/irfs4410.pdf and http://www.irf.com/product-info/datasheets/data/irfb4110pbf.pdf and compare the specs), both are widely counterfeited in China. More often than not the counterfeit parts are way off spec. Note the IR rated Rdson for the IRFB4410, 10 mohms!!! You can bet that the Chinese copies will be higher than that. Even if they aren't, then good IR manufactured IRFB4410s will have around 2.2 times the losses that an IRFB4110 would have, meaning they'll run around 2.2 times hotter and reach the thermal conductivity limit to the case much quicker, meaning a higher risk of failure.
ian.mich said:Fair enough, but these have been certified genuine 4410s by a local EE and other sources, and it's cranking 45A through 15 of them, i doubt there would be any problems
liveforphysics said:I would rather have a 6-fet made with 3077's for that voltage range of controller than a 15-fet made from 4410's, which you need twice as many of to equal a 4110.
