A-iPower GXS7100iRD 7100W Dual Fuel Inverter Generator Costco has this on sale for $999 as sale price. I think even at $1299 is a good price. The sale isn't going to last very long.

I just saw this thread, and don't remember ever seeing it, but I'd like to put in my 2 cents. I have been using and working with Austin and the crew at Electroandcompany.com for quite a few years. All my experiences with them have been, good, honest and responsive. I have heard from others...

Alessandro, Glad to help you. What year and model Honda's are you going to modify to electric. I have done this 2023 CRF and I am right now starting a 2005 CRF450R. As Bayodome mentioned Electro and Company is a great way to go. On this forum a guy just finished a Honda build of a 2006...

50AH at 72V is about 3.6KW of stored power. On the smaller bikes (KX80,85, 100, YZ85, etc) it takes about 100W per mile on trail riding, so the 20S8P battery we put in the smaller bikes is 2.4KW and 100W per mile gives you about 25 miles. We have gotten that quite often. More hills , harder...

I have 20S12P for 50AH. I actually have it split into 2 x 20S6P packs, so I can charge them faster at the track with 2 x 120V 15Amp chargers. It is pretty tight in the YZ frame. Here are some internal pictures of the battery. 10 x 6 times 4. Chi battery Systems sells a battery for Surrons...

Yes they are they are about a 80-90A fuse. It is the same area as a 1mm diameter copper wire. It has been empirically tested for that rating. The main bus bars are .4mm x 8mm copper strips which carry about 400A, also tested empirically, equivalent to a 2mm diameter copper wire. We have...

Did you buy one of these? They run good. We are running the tune that Austin is putting in this model. It runs real well with the EM260S controller, I anticipate it running better with the Tru Zapper at 35KW. We are at 28KW now and that is good, almost too much for my skill level.

Yes, doubling the battery might burn it up. The motor can usually handle more wattage for a while. I take the 100W Razor , leave the motor that is in it, and put in a 250w controller, and up the battery from 24V 5AH to 29V lithium 10AH. I don't see the controller in your video. Is it in the...

Here is his first race with the bike .

Thanks for the updates.

Hey F451, what are you riding right now? There are a few of us out there that are modifying existing great bikes ( YZ250F, 450F, CRF's KTM full size, old and new, frames) into some really fun track bikes and trail bikes. I have built quite a few, and I they are so fun. I built a 2017 KTM...

Here is the Aliexpress link. I use this size since we only use it for charging. I use the 20S version, 80A https://www.aliexpress.us/item/3256805881158602.html

Have you looked at the Molicel P42A cells. I get right at 40A out of each cell. I can test them by watching my max current on one side of my battery or the other side. I have 2 20S6P batteries in my 2014 YZ250F. I can select one or the other, and or both, and I can see about 240A out of...

We run most of our batteries with the BMS used only for Charge control. The discharge low voltage control is done with the Controller. I use the Votol controllers, and the have a Soft Undervoltage setting (which I set on my 20S12P battery at 65V), it slows the motor way down but still runs...

If you are an AMA member, and plan on racing ANY AMA race , I'm sorry, but we are explicitly excluded for any AMA competition. A friend with a Yamaha conversion wanted to try to qualify for Lorreta Lynns, and was told he couldn't. He called AMA and got Mike Burkeens on the phone. Simple...

Subsonic, I have to agree with Bayodome, no way are those mounts going to last. Beside not lasting, the motor is too high, the chain will wear out the rubber chain guides on the swingarm, while being very noisy. These motors are tearing out well designed mounts. The torque is huge. You are...
