Lately the hobby has taken a back seat to other hobbies.very cool, been an avid fresh/saltwater angler for almost 30yrs... havent given it up either but this hobby has most of my free time now lol

The long walk back to the car from the end of the pier in Milwaukee with 20-100lbs of salmon + gear at 3am was always killer. I contemplated using the dune buggy one of these times LOL. And I aways wanted to move to FL and take up saltwater fishing, but never made it happen.

robnewyork wrote:none of those will work with a yk43b ..only sla , rc lipo, and headway packrob pretty much laid it out... there are different lithium chemistries, some better suited to lower draw applications like an ebike with a brushless hub motor. your link is for li-ion which i would use with a lower draw setup, not industrial paired with yk43b. RC lipos on the other hand esp those with a higher C rating, maybe 30c and higher depending on the pack mAh.
Iworktofish wrote:3. Do lithium batteries have mounting/position ("this side up") requirements?i dont think so but it may vary from one chemistry to another... li-ion vs lipo vs lifep04 etc. they do have fairly strict requirements for long-term storage. and i wouldnt place them in a location where they're exposed to puncture, etc.
robnewyork wrote:AWESOME MAN , SOO HAPPY FOR U AND THE KID!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!I'm so glad you talked me into that cheap $65 industrial...best decision so far and works well with the cheap YK43B.
motor looks very well mounted and tore up that grass pretty nicely , yes go to 48v!!!
you just cant beat an industrial for the money , or even 3 times the money in this case..Whats the status on the other kart? did you try any other tooth count on this kart?
Iworktofish wrote:This 2nd YK43B has a different label than 1st one I have on my daughter's kart. I didn't know they were different.are the controllers the same size? i had assumed the one in the vid was not the YK43B but a smaller lookalike.
zen_racer wrote:are the controllers the same size? i had assumed the one in the vid was not the YK43B but a smaller lookalike.Thanks for the link. I just measured and the 2nd controller is smaller by 0.15" height, 0.2" width, and same length. I'm curious if the 2 are not the same, as the one that outputs more current should be running on my cart instead of my 9yr old's.
lookin' good @ 48v, love that takeoff sound! did you note the temps on the motor or controller after that run?
2nd attempt to link that leeson:

robnewyork wrote:i looked for aa good deal on a 12 v motor so you could run less batteries and have good top speed on the other kart but 199 new was the best i saw.Thank you for looking. That Leeson looks nice and the price is right. But the RPM's are less and there's no fan. I will look to eventually pick up an identical Ohio Motor...that internal fan I suspect will go a long way in keeping the motor from burning up at 1.5 and 2x the voltage. It will also be easy for my friend to make the same brackets and weld them to the frame. I'll pick this up if I don't find something cheaper in a couple weeks http://www.ebay.com/itm/Orion-V-Bus-Hea ... 0403240618

robnewyork wrote:heres a brand new motor that blows that motor out of the water for 25 more, 5400rpm at 36vThe Ohio motor is sized perfect that it just fits with minimal work. I'll have to size this one though to see.
