Can you provide web address for these parts, and what was the cost of just motor, battery, controller, and sprocket/belt. I'm doing this same thing but for my kids a ride to the bus stop, thanks for your time and hard work your buggy is rad
That's a lottta data.. lol.. If I were to do it again, I would not recommend doing it like this.. I'd recommend a Motenergy ME1306 and Kelly 500A brushless controller. The belt drive components came from Comet Kart Sales , the belt drive sprocket adapter plate came from AZUSA (custom). I built the battery myself out of LG 64aH pouch cells. When all was said and done, soup to nuts, that's $3500-$3700 sitting in the driveway and that was me buying a non running HH 150 for $750.
Where’d you get your windshield from? And also the led headlights?
This is great! Where did you get the seats? I've halfway finished a very similar conversion (non road legal yet) but haven't found seats and am still currently using the original gear box.
Thx Jeremy, I bought the rolling chassis w/ a non working gas engine and it already had the new seats. However, they are available from the factory here: hammerheadperformance.com/replacement-parts/body-and-frame/oem-seating
Thx! I just got some plexiglass and cut & drilled it. The headlights are stock ATV headlights that came w/ the hammerhead but I just replaced the bulbs w/ direct fit LED's.
That is an awesome build! Wondering if you could provide more details on the battery pack. I didn't see the 20s batteries in your ebay store. I am planning my first conversion ( 84 Honda 200trx quad) and could really use the help. I really appreciated your info on the belt drive in the comment response to Ron. How did you know/decide that you needed a 5:1 GR?
Thanks! The big reveal is coming soon of the most insane build I've ever done. I do have the 60 ah lipos on my site, I have 35 left, 15 are spoken for so I have ONE CASE LEFT of 20... www.ebay.com/itm/274872885106 The GR of 5:1 was learned from the Carter Superwheels conversion videos I first posted whereas I learned that 4:1 was too heavy, 6:1 was great, but left meat on the bones and 5:1 was "just right"..
The battery pack is 4.2v Lipo genuine LG 60ah cells in series. I don't have any at the moment but the ones for this build I got at Batteryhookup. They don't have any either. Regarding the gear ratio, the original series on my son's go kart details the research on 4:1, 5:1 and 6:1. The same situation applied here. 6:1 left too much top end on the table and 4:1 was overloading..
Awesome build! Why didn't u go with the Alltrax AXE7234 Controller?
Thanx! I just wasn't familiar w/ that one. I used the Kelly KDS-200 on a pre assembled board w/ the reversing contators / relays, etc. See link: www.kellycontroller.com/shop/kds-assembly/#controller. Works great!
@@TexasNEV yes, I see. That controller's got it all.
@@rona5945 Yeah it was a cool project.. This conversion is currently for sale on TexasNEV.com as well. I will be unveiling my next project in the next two weeks.. Will be my most aggressive radical project yet! A 100% complete scratch build!
@@TexasNEV Definitely looking forward to that!
This is really amazing - I definitely wanna try out a belt drive!
Would u be able to list the links to some of the items you used?
Specifically,
- the particular belt drive/sprockets on the Comet Kart website,
- the 200A Battery Management System via Android with Bluetooth,
- and the 5kW, 72V Lithium Ion Battery (20s, LG Chem Lipo cells, 60aH)
thanks in advance!
Thanx! Yes it was my most aggressive build yet. I think the big thing was all the red tape at the DMV where the real value is. Now that it has VIN and it comes up in the DMV as an electric vehicle, this is a steal for someone at $3795, far cheaper than a golf cart can go faster and does not have the restrictions, plus it is a lot more fun. (It is for sale).
However, to answer your questions, the driven sprocket and drive sprocket are not on Comet Kart Sales website, I had to call them and they came up w/ the solution for me.
It is a 17 tooth drive sprocket, 8mm pitch, 87 tooth driven sprocket, aluminum, 2 part clamshell. (5:1 gear ratio). I had to give them the distance from the motor shaft and the axle and they provided the belt to match! :)
The sprocket adapter plate was custom made for me by AZUSA. They have an enormous amount of sprockets on their site and can pretty much make anything you want.
The batteries, I sell on ebay (traderrje), and the BMS I got from www.lithiumbatterypcb.com
@@TexasNEV wow - that's really a steal, had no idea that you'd actually be selling it. If I weren't so deep into my investment here, I'd seriously consider it. At this point, I'm so far in, it'd be best to finish what I've started. I've got 2 kids, so everything I do has to be multiplied by 2! Thanks for the links. So why were the belt and sprockets directly off the shelf from Comet Karts not work for u? Why did u have to go custom with your belt and sprockets?
@@rona5945 Thanx! I think so too! I just wanted to get some capital back to finance my next project, a brushless 4 seater or Tao Tao Arrow high performance electric conversion...
As far as the custom nature of the sprockets, I don't think it is so much so "custom", I think it is just because Komet cart sales doesn't list everything they sell on their website, that's all. :) I think the 8mm pitch 84 tooth 1.5" wide two piece aluminum sprocket is on their site.. This might be it: cometkartsales.com/8mm-Belt-Driven-Sprockets/
@@TexasNEV Very cool - Never heard of Tao Tao Arrow, had to look it up. I saw 2 seater versions, but they look huge! Definitely looking forward to that build. Will that also be street legal?
@@rona5945 It is pretty big, but moreso long and wide, seems lighter than the Hammerhead even though the weight specifications are opposite.. We sold the first go kart in my video series, that was my son's, so the TaoTao Arrow is his.. if I make it street legal, then he can't drive it.. So I'll just have to pre stage it all to BE street legal but not actually do any of the paperwork until we decide to put this one on the webstore too. So, short version, while it is his, "no", but when it goes up for sale later, "yes". :)
what was your cost for this project? I would like to PM you and pick your head about a golf cart EV project. I'm in Dallas too
Sure no problem. :) You can contact me directly via e-mail from my texasnev.com website. Cost analysis varies based on what part you're wanting to know about. I had a bunch of repair and improvement costs to meet NEV guidelines that were over and above just the pure cost for the EV part.
I have a 2021 Hammer head GTS 150. Looking to make it street legal kart too. Living in Texas. This made me want to get to it ASAP. Any advice?
Gotta make it electric first.. Once that is done, I can assist w/ guiding you through the paperwork and the other equipment requirements necessary to get plates, etc.. Do you have the title?
i wanna do this with the massimo 200cc go kart is it possible i can just use parts from elect and co?
I don't see why not. Mange expectations on speed and torque if you are going to go with something with less power and torque than this one though. :)
How much would you charge to build me one?
Reach out to me offline. info at texas nev dot com
Can you pm me for a parts list?
That would be A LOT of stuff to document but the core components are a Motenergy ME0709 and the Kelly KDZ72550 controller assembly board w/ throttle. The motor sprocket is a 10 tooth 7/8 keyed shaft for #50 chain and the axle sprocket is a custom made 50 tooth #50 chain sprocket from AZUSA cut to spec to fit on any Hammerhead 150 or variant. However if I were to do it all again, I would do it differently. I would go w/ a brushless motor and controller and would have gone with a 40 cell configuration in a 20s2p for 120 aH.
Just saw this, sorry for the delay and I appreciate the information so much. I’d like to pick your brain one day and Venmo you for an hour or so of your time either by email or phone?
@@jefftolson796 No worries, I have a contact page w/ an e-mail link @ texasnev.com. I look forward to talking to you.
@@TexasNEV The link you provided will not work.
@@jefftolson796 info@texasnev.com is my e-mail address :)
The whole electric thing is dumb. But congrats making it street legal. I'll be attempting to do this after I R6 swap mine. I have the same cart
Gas golf carts in subdivisions are ok but gas hammerhead 150's arent? Doesn't make any sense to me but once it is an NEV (vs an LSV) it has far more automotive "rights" than a golf cart. :)
Really doesn't matter what you think about electric. The fact that this guy managed to convert it to electric and so such a clean job of it AND manage to make it street legal (probably just as difficult as converting it to an EV honestly) is respectable.
@@BunkerBlog Thx for the support. :) All good!
