I have taken the cells out of the Stark battery. As mentioned before THIS COULD BE DANGEROUS, OPENING A BATTERY LIKE THIS CAN BE DEADLY, IF YOU ARE NOT TRAINED, OR IF YOU MAKE A MISTAKE...WORK ON THIS AT YOUR OWN RISK I worked for 50 Years in the XRAY / NUCLEAR and MRI Medical industry, on the...

I have tried a few spot welders, and was never really happy with the welds, or I couldn't get penetration for the thick bus bars. I also saw that Alta, Stark, Chi Battery Systems and others, all had fusible links on every cell. Here is an early video of how we made fusible links. Since then...

If you look at the complete open battery above in pic 5931, you can see the bottom tray. The bottom tray wasn't complete in pic 4352, and those batteries were from a KTM Freeride (There was another row of cells on top of the flat group already there.). I could only make it 20AH 72V for the...

Yes if you build one of these, you will be building 5 or more. I have a lot of friends, that I helped them build one, or built one for them, that have built a bunch more. So go get the welder, and start learning. Get an inexpensive MIG welder, 100-120A, one that accepts gas. Start with that...

Hello Mr. D_Daly, welcome to the Forum. Yes your bike works perfectly for this type of build. Go to post #11 in the article, (Your post is post #26), the first picture in that post is a "90's model that I build. A bit different in the motor mounts and a simpler shape for the battery. The...

This all bids more questions??? I have run the QS138 70H V3 motor almost exclusively. With the EM150SP/2 for smaller bikes and lots of EM260SP/2 and EM260S controllers on the full size bikes. I am dabbling with the FarDrivers now, but no real experience yet. I have never overheated the motor...

Mike Burkeen, of the AMA, spoke with Steve Agular today with some great news. They are going to have an Official Electric Class race included in the Washougal, WA, AMA Pro Motocross weekend during the Amateur days of the event. There is also going to be a Open Electric Class at the Mammoth...

Costco has a sale on the ANKOR SOLIX F3800 with second battery and 400W of solar panels for $4599.99 In the online catalog it is item no. 1884308

Yes it is. We live in western Arizona and ride mostly So Cal tracks, and it is hot in the summer months. If the controller doesn't get airflow, (a lot of airflow), they will overheat. running between 300-400A with the Votol controller EM260S Stock right radiator and Amazon pump...

Did you lay down those near perfect welds on you Battery box structure. If those are your work you are one fine welder. I always have to preface my welds, with "they may not look pretty but they are solid"... Glad to be of help in your builds. You are now your own professional at building...

Thanks B.Frank. I enjoy building these things. There is a friend of mine in Florida, who has a great quick change system, XEMX1.com But they are primarily for 2014 and newer YZ250 and 450F bikes. I haven't quite got my quick change system done yet, but I will have it on my KTM soon. Thanks...

Oh yea, you will need a box of these connectors. https://www.aliexpress.us/item/3256805179431061.html?spm=a2g0o.order_list.order_list_main.56.240a1802BoX8pH&gatewayAdapt=glo2usa

Here is the Wiring Harness, 72 to 12V converter, Power Relay, key switch, blinker. https://www.aliexpress.us/item/3256802561424753.html You will then need to get the left and right side handlebar swtiches, and throttle. You can remove the right side switches from the throttle to put a more...

You are certainly welcome. I’ll get with you and we’ll get the street legal stuff working, and the water cooling system on it. Is the controller in the picture your new controller? My controller has a flat machined bottom. They are so fun to ride.

I did install this same size battery from Amorge with the EVE40P cells ( less expensive, only 4000mah but 35-40AH) A couple of differences in this battery is Open Discharge, to reduce the heat inside the battery Box, Dual Charger ( 2 ports for 2 chargers, faster charging at 120VAC) and the...
