Thank you for the LHRB info.

Thank you @DonCox for all your great tips. I agree with you opinions on the noisy generators. I have a big 6kw 110v/220v MQ generator and a smaller 3500 watt 110v generator. In both cases I place a styrofoam igloo over the to reduce the ruckus! I went ahead and ordered a charger from China...

Very nice build! Are you using the LHRB Honda cable OX- Brake? We are on a similar path. I too am waiting for my Amorge 20s14p battery to arrive.

Thank you for all the recommendations. What do you guys recommend for as a great charger? There seems to be a sea full of options. I'd love to be able to quick charge at the track. Best to all, Dave

Hey Guys, I'm looking to add a 72v to 12v buck converter. The 12v circuit would be used for running less than 50w of accessories such as a water pump, and a GPS. Any buck converter recommendations?

I may buy one and give it a test.

Has anyone tested any of these VESC based controllers? h ttps://flipsky.net/products/flipsky-fsesc-75450-84v-high-current-350a-esc-base-on-vesc-with-aluminum-case-water-cooling-enclosure-for-e-foil-fighting-robot-surfboard-agv-robot

Here is a photo showing the motor mounts pinched between the three tubes. There is no movement once the swing arm is tightened. Hope this helps.

When I first started installing the motor mounts I was super concerned with the Lithium-King motor mounts sliding around on the 17mm ID x 20mm OD tube. I wanted more support. I ended up fabricating three tubes that would slip over the 20mm OD and sandwich the the motor mount plates. I had to...

I agree wholeheartedly. The Lithium-King universal stainless steel mounts seam fairly solid. Custom fitted and welded mounts will undoubtedly provide greater strength. And, they will look trick. Everyone's input is so appreciated. I am certain there will be several improvements to make after...

Nice schematic. So, you are running the on/off switch in parallel on the B+ power cable. You are recommending a 400A fuse on B+ upstream from the switch. Questions: 1. Just a simple break in the connection, with little to no load, is enough to cause concern? 2. The EM260 control has a 300A...

Hi Guys, My E&C motor and controller kit arrived today. Thanks to everyone's tips I've been able to make some major progress. Now I have to wait patiently for the battery. Here is a video showing the status of my CRFE build:

I just now emailed Allen at Amorge and asked to change from 45A to 45B cells. Thanks guys.

Hello guys, I found a few extra millimeters for more storage. I've changed the size of the battery to give me 20s13p for 72v 58.5Ah. I'm totally stoked! Here is the final battery box size:

After following the advice from several members of the group, I'm making great progress with my 2011 Honda CRF 250R conversion. I'm waiting for my E&C kit. During the wait, I 3D printed a mock-up motor. This allowed me to fit check the Lithium King motor mount and to design an irregular shaped...

Thank you for the great post! Please keep us updated once you receive the pricing and final configuration for the battery. We are all fighting this same battle trying to get the most battery in the available space. -- Best, Dave

My motor and controller are on order. I'm desperate to get started with the build. Thus, I'm 3d printing a mock-up motor.

Here is a mockup of version 2 battery with the cells positioned vertically. This layout allow 280 cells for 20s 14p. The 2010 true 2013 CRF 250R frame is just too tight.
